Key Factors of Push Button Switch

Push button switch is a common type of component in our daily life, whether it is industrial instrumentation, medical equipment, anti-theft machines, electronic amusement equipment, household appliances, office automation machines and automobiles, airplanes, ships, computer keyboards, digital converters, children’s toys and industrial automation Systems, even the operating systems of cutting-edge aerospace technology and military installations, have buttons in all electronic products. Today, the editor will talk to you about the specific content of many common sense issues related to buttons. 

The structure, function and symbol of push button switch

The function of the push button switches are mainly used in electronic equipment to turn on or off the power source and change the power circuit to change the working condition of the machine. For example, the frequency band and frequency of the communication machine are changed, the channel of the TV receiver is changed, the function of the tape recorder is changed, the range of the measuring instrument is changed, and the control of various power circuits, etc.

Structural characteristics of the switch. A large part of the button is composed of the outer shell, insulating sheet, handle, contact, lead device, reset key spring (self-locking device), and fasteners. Among them, the shell and insulating sheet are made of ABS engineering plastic and insulating bake-lite; the handle, reset key spring, and fastener are made of metal; the material of the lead device is mostly copper alloy; the contact for the button Generally, silver-copper alloy or sterling silver is used.

3 The graphic symbol (circuit symbol and symbol picture) of the button in the power circuit is shown in Figure 1. Among them, the symbol picture was expressed by “K” in the past (the button switch also used “AN”), and the new regulations use or “ XS” expression.

How does the push button switch work, and what are the main applications?

Push button swtiches are different from linear power supplies. Most of the switching transistors used in push button swtich switch between fully open mode (full zone) and fully closed mode (cut-off zone). Both methods have low dissipation characteristics. Switch between The conversion will have higher dissipation, but the time is very short, so it saves energy and generates less waste heat. Ideally, the push button swtich itself does not consume power. Voltage regulation is achieved by adjusting the time when the transistor is turned on and off. On the contrary, when the linear power supply generates output voltage, the transistor operates in the amplifying area and consumes power. The high conversion power of the push button swtich is its big advantage, and because the push button swtich has a high operating frequency, a small standard and light-weight press can be used, so the push button swtich will be smaller than the linear power supply standard, and the quantity will be relatively light.

If the high power, volume and weight of the power supply are the main considerations, the push button swtich is better than the linear power supply. However, the push button swtich is more complicated, and the internal transistor will switch frequently. If the switching current is processed, noise and electromagnetic interference may occur to affect other devices, and if the push button swtich is not specially planned, its power factor may not be high.

 push button swtich products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating air purifiers, electronic refrigerators, liquid crystal displays, LED lamps , Communication equipment, audio-visual products, security monitoring, LED light strips, computer cases,

Digital products and instruments and other fields.

 Noise comes from three aspects: PCB planning, circuit vibration and magnetic components:

 1. Circuit vibration

The power output has a great low-frequency wave stabilization. Most of the circuit stability margin cannot be caused. In theory, the frequency domain method/time domain method or the Routh criterion in the system control theory can be used for theoretical analysis. Now, computer simulation methods can be used to conveniently verify the stability of the circuit and avoid self-excited vibration. There are a variety of software available. Regarding the completed circuit, it can be improved by adding output filter capacitors or inductances, changing the signal response orientation, increasing the integrating capacitor of PI conditioning, and reducing the open-loop amplification factor.

 2. PCB planning

Mainly caused by EMI noise. RF noise adjusts the PI conditioner to make the output error signal contain disturbance. Mainly check whether the high-frequency capacitor is too far away from the component, whether there is a large C-shaped coiled wiring, etc.

There are at least two points on the PCB line of the control circuit shared with the power circuit. PCB copper clad wire is not an ideal conductor, it can always be equivalent to an inductor or a resistor. When the power current flows through the PCB wire shared with the control circuit, a voltage drop occurs on the PCB. The nodes of the control circuit are loose in different directions. At this time, the voltage drop caused by the power current adds disturbance to the control network, causing the circuit to emit noise. This flash occurs mostly on the power ground, pay attention to single-point grounding to improve.

 3. Magnetic components

Magnetic materials have the characteristics of magnetic to strain, and the enameled wire will also be affected by electromotive force in the leakage magnetic field. Under the action of these elements, overtone or 1/N frequency resonance will occur locally. It can be improved by changing the switching frequency and the dipping of the magnetic components.

Seventy-two changes of micro switch

In fact, the micro switch is a seventy-two changeable component. It will appear in our lives in different forms and act as a convenient gadget. Putting a mouse shell on it changed its name to mouse. Enter the body of the microwave oven and it becomes the button of the microwave oven. After looking for it carefully, I found that it is right by our side, and it is everywhere in our lives. It plays an irreplaceable role in our daily life. It realizes automatic control and safety protection in equipment that requires frequent circuit switching. .

At present, it has been widely used in electronic equipment, instrumentation, mines, power systems, household appliances, and military fields such as aerospace, aviation, missiles, and tanks. In addition, they can also be used in computer mice, car mice, automotive electronics, communication equipment, military products, as well as testing instruments, gas water heaters, gas stoves, small household appliances, microwave ovens, rice cookers, floating ball equipment, medical equipment, Building automation, power tools and general electrical and radio equipment, 24-hour timer.

The quality difference of the micro switch will obviously reflect the difference in hand feeling when we use it. Now, whether we live, work, study, or entertain, micro switches have become indispensable. Take the mouse as an example. Many times a wonderful click will make us fall in love with that feeling.

The mouse is an important peripheral of the computer, and the mouse is absolutely indispensable in the multimedia computer. Although the operation of the mouse is very simple, there are only two actions, "move" and "click", but these two actions play a vital role in our use of computers. Now standard computer operating software uses a graphical interface to specify with a cursor Then click the mouse to complete the operation instruction, which greatly facilitates computer users.

What I love to say is the needs and desires of hands. Everyone will love the light and accurate switch feel. Our fingertips have forgotten that we are working hard, as if we are dancing lightly. Micro switches are also called sensitive switches and snap switches, which are switches that use very small forces. In addition, it is also a switch in which external mechanical force acts on the moving reed through a transmission element to quickly connect or disconnect the fixed contact and the moving contact at the end. Every time we click, the micro switch will repeat the movement, and a qualified mouse requires at least 30,000 to 100,000 continuous clicks, and even a high-quality micro switch will reach millions of switching times. After such a long time of overloading and repetitive work, the entire part is not overheated or deformed, and will not affect the use experience. The selection of manufacturing materials must be strict.

The micro switch, which is closely related to the "click" performance, can be said to be the soul of the mouse. Most of the reasons for the damage of the mouse are the failure of the buttons, and the probability of failure of other components in the mouse is actually very small.

It is the micro switch under the button that determines whether the mouse button is sensitive. There are reasons for the most frequent use of the button. The quality of the micro switch is directly related to the feel of the mouse button and the service life.

How to choose high-quality power sockets in daily life

Sockets cannot be bought casually. Sockets are the bridge between power supply and electrical appliances. It is related to the daily "big safety" of the family, and the smaller the things are, the easier it is to be overlooked. In fact, there is a lot of information on the switch, so how to choose the switch power socket during the decoration process?

The main difference in socket prices lies in the materials used, internal structure and appearance design. Inexpensive products are often compromised in material, touch and durability.

1. Material

Good power socket will use PC materials. When selecting, it’s best to do a combustion test on its core components. PC material has the characteristics of moisture resistance, heat resistance, flame retardancy, and high impact resistance, and has very good resistance to ultraviolet rays, and it will not be used for a long time. Will change color.

2. Appearance

The surface of a good quality socket should be flat, smooth and round, with fine material and good color, with ceramic white, no black spots, shrinkage, gas lines, burrs and other problems.

Three, feel

You can pick it up to see how much it weighs. Usually, good shell insulation materials, high-quality contacts, and current-carrying copper sheets are heavier. A good socket spring has moderate hardness, excellent elasticity, and has a strong opening and closing transition. The touch feel is light and not tight. Good switches generally have harder springs and have a strong sense of force when switching, while poor switches are very soft. If they are too soft, they may be made of ABS material, and the switch handle often stops. The phenomenon of the middle position.

Fourth, the internal structure

For the socket, the first thing to consider is its safety. The safety protection door of the socket is indispensable, you should try to choose the product with the protection door when choosing the socket. Secondly, check the tightness of the socket clip. Smooth insertion force is a key factor. The plug should require a certain amount of force and cannot be inserted with one foot. This effectively reduces the occurrence of power outages caused by non-human factors. At the same time, the socket clip is made of high-quality tin-phosphorus bronze, which has good electrical conductivity and strong fatigue resistance, and guarantees the socket plug-in cycle up to 10,000 times (the national standard is 5,000 times).

Five, safety certification

Qualified switches and power socket are compulsory certification products stipulated by China Quality Certification Center. Please confirm the 3C mark and the implementation of the national standard number on the product when purchasing. Each switch socket base is engraved with a trademark, a certificate of conformity, and a 3C certification Sign.

In addition, we recommend that you pay attention to the logo on the base of the switch and socket and the rated current and voltage when purchasing.

What Is a Guitar Pedal? How to choose yours Guitar Pedal?

A Guitar Pedal, sometimes known as an effects pedal, a stompbox, or an effects unit, is an electronic device that alters the sound of the instrument connected to it in some way. Pedals are closely associated with guitar players and the electric guitar. Vocalists and other instrumentalists can also use guitar pedals to produce unique and interesting effects.

Types of Effects Pedals

Effects can generally be grouped into four different categories: gain-, time-, modulation-, and filter-based. A fifth category — multi-effect pedals — is a fairly recent development, due to advances in DSP (digital signal processing) technology.

Gain-based pedals

This category, in order of increasing gain and available distortion, includes compressor, boost, overdrive, distortion and fuzz pedals.

Compressors, like the MXR Dyna-Comp and BOSS Compressor/Sustainer, are intended to even out playing dynamics and can be used to either push or tame your levels. Clean boosts, which are exactly what the name implies, include the MXR Micro Amp and MC-401 Boost, BBE Boosta Grande, Rockett Archer and Friedman Buxom Boost.

Overdrives are intended to push an amp that already slightly broken up into a more saturated distortion. They include classics like the Ibanez Tube Screamer, Fulltone OCD, Wampler Euphoria and many others. Distortion pedals up the ante even further, providing a fatter, more clipped sound.

Fuzz boxes provide that completely over the top, totally square-wave clipped sound of an amp on the edge of total breakdown. These include classics like the Electro-Harmonix Big Muff ∏, Fuzz Face from Dunlop and Way Huge Swollen Pickle. There are also fuzzes that provide an octave up or down like the MXR SubMachine, Catalinbread Perseus and Fulltone Octafuzz.

Time-based pedals

Shifting your instrument in time, whether it’s to match the natural reflections of an acoustic space or create a complex layer of repeats, is easy with reverbs and delays.

For classic room, chamber, hall and plate delays, choose pedals like the MXR Reverb, Electro-Harmonix Oceans 11 or TC Electronics Hall of Fame.

For multiple repeat delays there are a wide range of both analog and digital delays. If you prefer the analog world, the MXR Carbon Copy, EH Deluxe Memory Man and Way Huge Aqua Puss provide that unique sound. On the digital front, the range starts with simple digital delays like the BOSS DD-3 and Mooer Repeater,

More sophisticated pedals, like the Line 6 DL-4 or TC Electronics Flashback, offer a number of delay types. Some can even provide multiple delays at the same time.

Modulation-based pedals

Hear that pulsing, swooshing, jet-plane sound? That’s modulation pedals at work. Tremolo and vibrato, phase shifters, flangers and rotary speaker emulations all use use shifting time bases, volume or swept filters to work their magic.

Tremolo is a variation in volume, and vibrato a variation in pitch, though the terms are often used interchangeably. There are lots of options for tremolo pedals, from the Danelectro Tuna Melt to the tap-tempo-equipped Walrus Audio Monument.

Phase Shifters add a sweeping multi-stage filter for that classic “swoosh,” and include the MXR Phase 90, Electro-Harmonix Bad Stone and the many variants on the classic Uni-Vibe sound.

Flangers, which use a very short time delay sweep, have a distinctively different type of sweep that keeps a harmonic relationship to your music. Classics include the EH Electric Mistress and MXR Flanger. New takes on the effect include the TC Electronic Vortex and Thunderstorm, and the Keeley BubbleTron, which combines a flanger and phaser in one Guitar Pedal.

Filter-based pedals

From EQs to wah pedals and envelope filters, pedals that utilize frequency filtes can shape your sound in many ways.

EQ uses a series of filters to raise and lower different frequency ranges. While it’s not common to think of it as an effect, it can certainly be used as one, making your instrument sound like it’s coming over a telephone line, or through a cardboard tube. From graphic EQs like the classic MXR 6-Band to parametric EQs like the Empress ParaEq pedal, there are many to choose from.

The first wah pedal quickly moved beyond being a novelty to something every guitarist had to have. Classics like the Dunlop Cry Baby or Vox pedals have been joined by new models from those companies and others like Fulltone, Morley, Boss and Voodoo Lab that allow adjustment of the filter depth, width or center frequency for an individually fine-tuned result.

Envelope filters, often called auto-wahs, trigger a filter to sweep up or down when the input hits a specific threshold. This can give each picked note or strummed chord its own sweep while saving a lot of wear and tear on your foot. Electro-Harmonix, MXR, BOSS, Fender and boutique pedal companies like EarthQuaker, Aquilar and Keeley provide a wide range of Guitar Pedal in this category.

Multi-Effects

Advances in digital technology have given us many things. Not the least of these are the DSP-based multi-effects pedals that put a huge library of new and classic effects right at your feet. Korg, BOSS, Line 6, Headrush, Kemper and others have a range of choices that can take you from a basic selection of popular effects to a unit that packed hundreds of digitally modeled effects, amps, cabinets and studio wizardry into a performance-ready package that’s ideal for any gig from a coffee house to a stadium.

What is a DIP Switch?

DIP is short for Dual In-Line Package. They are designed to be mounted on printed circuit boards and are commonly used to customize the behavior of an electronic device for specific situations.

The way Dip Switches work?

DIP switches refers to a set of electrical switches packaged in a small box or housing, which are arranged in a line or circle (rotary DIP). The function is to provide a range of electrical inputs to an electronic device based on the position of the individual switches within the line or circle.

Pros & Cons:

DIP switches are an alternative to jumper blocks. Their main advantages are the ability to quickly change positions and the fact there are no parts to lose. In recent times DIP switches have lessened in popularity due to the rise of easily customizable software configurations.

However, they are still used for a variety of functions, especially within industrial equipment. They provide an inexpensive solution for circuit design, with the convenience of checking their configurations without the system being turned on.

Push buttons and their widely used applications across industries

Push buttons can be explained as simple power controlling switches of a machine or appliance. These are generally metal or thermoplastic switches that are intended to grant easy access to the user. The idea of electric circuits is that the electricity should be able to flow uninterrupted through multiple wires and components. However, circuits that are always complete aren’t as useful as the ones that work only when required.

The design of the push button is such that it can accommodate a human finger to control the system easily. For machinery with complicated operations and various buttons, there are donations for separate colours of the push button. This enables users to identify what function the switch is bound to perform. For our daily applications, there are scarce guidelines for the colour of the button, since only a few of them are common across multiple industries. For example, the red button frequently functions as the power button, while yellow indicates a pause. For industrial applications like machinery, the colour meanings are more firmly defined in international standards. Contact Bituo for Push buttons now!

Basic knowledge of Auto switches

Whether they’re toggles or rockers, push-button or disconnect, switches are found in every 12V electrical system, doing everything from turning on lights to moderating critical systems. To understand the basics of electrical switches, you should first understand the internal circuitry. Then you can discern the difference between the different types of Auto switches.

SPST and DPDT

These acronyms represent the poles of the switch, and the number of poles (“S” for single, “D” for double). This is one of its most basic features. Poles are the number of circuits the switch can control, and throws represent the number of positions in which a switch can close a circuit. A single pole (SP) switch controls only one circuit. Similarly, Similarly, DP switch controls two circuit to connect two identical mechanical switches.

2 of the most common configurations are single pole single throw (SPST) and double pole double throw (DPDT). SPST is best known as the humble ‘on/off’ switch we use every day. The other one DPDT allows for the use of tandem circuits.

DC & Audio Connector Basics

While many connectors carry power in addition to data, some connectors are used specifically to provide power connections to devices. These vary widely by application and size, but we will only focus on some of the most common ones here.

Barrel Connectors

Barrel connectors are typically found on low-cost consumer electronics which can be plugged into wall power via bulky AC wall adaptors. Wall adaptors are widely available, in a variety of power ratings and voltages, making barrel connectors a common means for connecting power to small projects.

The female barrel connector, or “jack”, can be purchased in several varieties: PCB mounted (surface mount or through hole), cable mount, or panel mount. Some of these connectors will have an additional contact that allows the application to detect whether a power supply is plugged into the barrel jack or not, thus allowing the device to bypass batteries and save battery life when running on external power.

Female barrel connector. When no plug is inserted, the “insertion detection” pin will be shorted to the “sleeve” pin.

The male barrel connector, or “plug”, is usually only found in a wire termination variety, although there are multiple methods of attaching the plug to the end of the wire. It’s also possible to get plugs that come pre-attached to a cable.

Unattached male barrel plug, for attachment to any power supply. Note that the sleeve connection is designed to be crimped onto the wire for extra strain relief.

Barrel connectors provide only two connections, frequently referred to as “pin” or “tip” and “sleeve”. When ordering, there are three differentiating characteristics of a barrel connection- inner diameter (the diameter of the pin inside the jack), outer diameter (the diameter of the sleeve on the outside of the plug), and polarity (whether the sleeve voltage is higher or lower than the tip voltage).

Sleeve diameter is most commonly either 5.5mm or 3.5mm.

Pin diameter is contingent upon sleeve diameter; a 5.5mm sleeve will have either a 2.5mm or 2.1mm pin. Unfortunately, this means that a plug designed for a 2.5mm pin will fit in a 2.1mm jack, but that the connection will be, at best, intermittent. 3.5mm sleeve plugs usually mate to a jack with a 1.3mm pin.

Polarity is the final aspect to consider; most often, the sleeve will be considered 0V and the tip will be a positive voltage relative to the sleeve. Many devices will have a small diagram indicating the polarity expected by the device; care should be taken to adhere to this, as an improper power supply may damage the device.

Plugs of both sleeve sizes are usually 9.5mm long, but longer and shorter ones do exist. All BITUO products use a negative 5.5mm sleeve and a positive 2.1mm pin; we recommend sticking to that standard where possible, as it seems to be the most common flavor found in the wild.

How to Wire Rotary Switches？

A rotary switch connects several devices to an electric source. The electricity enters the rotary switch’s input terminal and the switch sends electricity to the output terminal selected. Some rotary switches contain more than one circuit. These contain two or more input terminals, called “poles,” and each input circuit connects to multiple output terminals, or “ways.” A 2P4W rotary switch contains two poles and each pole connects to four ways. The center terminals on a rotary switch connect to the electric source and the terminals around the outside of the housing connect to the devices.

Step 1

Find the rotary switch’s “1” output terminal for each input terminal. Some rotary switches have labels stamped into the housing next to the terminals. If not, turn the switch to the “1” position. Place one ohm meter probe on the input terminal and touch the output terminals with the ohm meter’s second probe until the meter reads continuity. Consider the terminal with continuity “1.”

Step 2

Prepare the wire ends for the rotary switch. If the wires solder to the rotary switch terminals, remove 1/4 inch of each wire’s insulation with wire strippers. In all other cases, install the proper terminal connector on each wire.

Step 3

Attach the power supply wire to the rotary switch’s input terminal. If the wires solder to the rotary switch, hold the power supply wire against the input terminal and apply solder with a soldering iron and solder. If the rotary switch uses terminal connectors, push the power supply terminal connector on to the input terminal. Repeat this for each rotary switch circuit.

Step 4

Secure the device wires to the rotary switch’s output terminals with either the terminal connectors or solder. Connect the first device to the “1” terminal, then connect the remaining devices in the order of operation with the second device connected to the terminal clockwise of the first terminal, the third clockwise of the second, and so on. Repeat this on each rotary switch circuit.

What is 3PDT Switch? How to wire 3PDT Switches?

Before going any further, you have to understand how functions a 3PDT switches 3PDT footswitch. The 3PDT stands for “3 poles, double throw”. Here is a diagram showing the different possibilities:

Here, we can see that a simple pole, simple throw (SPST) is equivalent to a simple on-off switch; simple pole dual throw (SPDT): equivalent to a toggle switch. So basically, double throw just means that you have two positions for the switch.

A dual pole, simple throw (DPST) is equivalent to 2 SPST, DPDT: equivalent to 2 SPDT.

From that we can easily conclude that a 3PDT is equivalent to 3 double throws at the same time. You have two position for 3 switches with 2 positions each:

That means to say that on one position, the middle pins are connected to the ones of the top (2 is connected to 1 for instance), and in another position to the ones on the bottom of the switch.

How to use it for true bypass?

When you want to do a true bypass, you want a simple thing:

in one position (position 1), input and output jacks are directly connected, the signal does not goes through the circuit (bypass)

Position 2: input jack goes to the input of the circuit, the output of the circuit is connected to the output jack, and a beautiful shiny LED is on.

For position 2, there are 3 conditions to be filled, that is why we need a 3PDT !

With this type of wiring, we have the two following positions:

That is to say on and off for the guitar pedal!

If you do not want to bother to solder directly on the 3PDT (you have to be precise and it is not very practical if you want to modify it afterwards, and most of the times it does not look so good), you can directly use a small PCB to make your true bypass like a boss. Contact us for more information now!

How to choose the best Car USB Charger to be fitted in your car?

It is convenient to charge phones and many other devices that can use cables linked to USB sockets for charging.

Sometimes cars or vehicles may not be fitted with USB connections, or it may be that a variety of devices need to be charged using a USB charger whilst on the move in a vehicle.

In many instances, a USB charger that takes power from the vehicle’s cigarette lighter power socket can be invaluable.

Knowing what to consider when buying a car USB charger is key to making sure you make the best buy.

What is a car USB charger?

A car USB charger is a small adaptor that plugs into the cigarette lighter/accessory port found on virtually all cars and provides one or more USB outputs.

As the cigarette lighter/accessory port provides a nominal 12 volts output, the car USB charger converts this voltage to the 5 volts required for the USB supply.

Also as the car 12 volt supply can vary considerably and also have spikes and surges on it as a result of the other car electrical systems. The car USB charger needs to protect against these so that anything connected to the USB port will not be damaged by this.

In its basic form the car USB charger can be used to charge a host of devices from smartphones and tablets to power banks and even certain models of camera. It is worth remembering, though, that the cigarette lighter/accessory port on the car is only active when the engine is running. This is done so that the car battery cannot be discharged accidentally by leaving a heavy current appliance in the socket.

Some car USB chargers can contain a lot more functionality, acting as a connectivity hub – some are able to connect to music players including mobile phones and radiating an FM signal to be picked up by the car radio. This can be very useful if no USB functionality exists in the car. They may also enable hands-free phone calls to be made.

These car USB chargers are very useful when smartphones are used as satnavs with applications like Waze as they tend to use a lot of battery as the screen is live all the time. They can also be useful for keeping batteries for the tablets etc. used to keep the children happy on long journeys.

What to consider when buying a car USB charger?

When buying a USB charger, there are a number of points to consider – buying the best USB charger will mean that it will fulfil its purposes.

Multiple sockets:   Consider what you might want to charge. How many devices are you likely to want to connect at any one time? Most car USB chargers have two outputs, and this is often enough, but if there is a possibility of more being required, then car USB chargers with four outputs are also available. As the cigarette lighter/accessory ports are often located near the gear lever or other controls for the car, be careful not to have too many leads in this area. In some cars, there are power ports behind the driver, in the back seats, etc. For keeping children occupied on long journeys, a four ports car USB charger may be more useful here.  Click here our BTC2013 series for more details.

Size:   It is worth considering the size of the car USB charger. This can be important if the 12 volt lighter / power point is located close to any of the driver controls. Check that any USB charger will not obstruct anything, and the leads can also be routed away from the vehicle controls. Some of the chargers with more outlets and more functionality have to be larger and often taller. Check that any device can be accommodated easily.

Power output:   Not all the outputs on the car USB charger may be the same. Check the current capability they provide. They provide around 2.1 or 2.4 amps dependent upon the device, but check what you need.

Car USB chargers providing 2.1 and 2.4amp are now common. It’s important to get one with a good output as a charger that is lower rated than the device requires means it will take longer to charge. Make sure that the output is available on all the USB sockets. Some chargers may only have a high output on a limited number of their outputs, so check the small print.

The newer smartphones and tablets can consume more power to charge them as the batteries are larger. It is best to check the details on the wall charger provided with the phone and then ensure the car USB charger that is bought has at least one socket with the required output.

Smartphones are ideal for use with apps like Waze, etc that provide driving instructions. The constant screen usage combined with at of the GPS that needs to be constantly updated drains the battery faster than usual. This means that it is particularly important to have a car USB charger that can provide sufficient power to power the smartphone. A typical 2.4 Amp capability should be sufficient in most cases, but it is always best to check.

Fast charging:   Most of the latest smartphones incorporate a form of fast charging. There is the Qualcomm Quick Charge Samsung Adaptive fast Charge and Apple PD. These standards enable a much faster charge to be obtained, whilst not unduly degrading the long- term performance of the battery in the device. As the Qualcomm Quick Charge standard is used across a variety of smartphones, this one is found in some car USB chargers. Check what your phone supports if you want a fast charge capability. Click here our QC series for more details.

Quality:   The term quality can be a particularly vague term, and one which is very hard to assess. Often the popular brands or those with good review ratings will best. It is worth thinking about the cost. Although this is not a complete indicator, the exceedingly cheap ones are unlikely to have all the testing and safeguards in place. After all, the better brands have a name to protect, so that are likely to make sure their products are reliable and conform to the right standards. Would you trust you really expensive smartphone on a car USB charger that costs just a dollar / GB pound / Euro? It is worth spending a little more for peace of mind and the better quality you are likely to get.

Don’t buy cheap car USB chargers of dubious quality – these are likely to compromise on certain safeguards that other models provide for handling the fluctuations in voltage that occur around car electrics or for taking care of overheating problems. It’s just not worth it.

There is a huge variety of car USB chargers on the market. Fortunately, most of the reasonably priced chargers are reliable and provide excellent performance. Provided that you don’t go for the exceedingly cheap ones available and you select one that has broadly the right functionality and capability, then it is likely to give good performance. Bear in mind points like accessibility, likely reliability, built in leads, and output capability and all should be fine. If you need additional functionality, again, don’t go for those are too cheap, and check the functionality is exactly what you need.

Milestone in BITUO ELECTRIC starting from RFI/EMI Filter

The EMI filter is a filter circuit composed of a capacitor, an inductor and a resistor, also called RFI Filters or radio-frequency interference filters. Its filter circuit composed of capacitor, inductor and resistor. A passive two-way network: One end is the power supply and the other end is the load. The principle of the EMI filter is an impedance matching network: the greater the impedance adaptation between the input and output sides of the EMI filter and the power supply and load side, the more effective the attenuation of electromagnetic interference is. The filter can effectively filter out the frequency of a specific frequency in the power line or the outside frequency to obtain a power signal of a specific frequency or eliminate the power signal after a specific frequency point.

For Medical Applications, our entire IEC Inlet/Power Entry Modules, single phase and three phase EMI filters are available as Medical Grade EMI Filters to comply with both patient and nonpatient low-leakage current requirements for medical equipment. Our Telecom EMI Filters encompass all AC/DC power networks and are designed to meet all applicable standards such as NEBS, CE, etc.

BITUO provides solutions for Tempest for land, shipboard and airborne environments.

Additionally, our Inverter EMI Filters provide cost effective solutions for industrial machinery, VFDs, drives, solar and wind with the best lead times in the industry.

From May 2019, we set up strategic partner relationship with BYD. As one of the leading companies in China for new energy, BYD always has its own high standard to choose supplier.

For BITUO, this cooperation can better promote the development of the company and make more contributions to the society.
