Touch Switch Purchasing Guide

Concept

Touch switch is an emerging product developed with the development of science and technology. It refers to a wall switch designed using the principle of touch sensing chip. It is a replacement product of the traditional mechanical button wall switch.  that can be more intelligent and easier to operate have incomparable advantages over traditional switches. They are currently a very popular decorative switch in home and office products.

Principle

The human body is charged at the same frequency as the mains. When the human body touches or touches the switch, it becomes a standard MOS level after clipping, amplification, and shaping at the input buffer level.

Run logic

When the touch duration is greater than 32 milliseconds and less than 332 milliseconds, the control circuit of the control logic part is in a switching state. When the touch duration is greater than 332 milliseconds, the control logic part of the control circuit is in a dimming state, and the output trigger pulse phase angle changes continuously and periodically between 41° and 159°, and is divided into fast and slow according to the sensitivity of the human eye. and pause three processes.

When the touch ends, the brightness memory remembers the phase angle at that time. If another touch is applied for more than 32 milliseconds and less than 332 milliseconds, when the circuit is in the off state, the phase angle is still memorized by this part to ensure that the circuit is in the open state next time. , maintain the original selected phase angle, and the light source maintains the original brightness. The trigger pulse is synchronized with the mains power, and the phase-locked loop ensures that the circuit's working clock is also generated by it. At the same time, the circuit also has remote control (i.e. remote triggering) function and sleep (i.e. from light to dark, and finally off) function, the duration of which is set by the external circuit.

Features

1. Applicable to a wide range of lamps, it can be connected to common lamps such as fluorescent lamps, energy-saving lamps, incandescent lamps, spotlights, halogen lamps, etc. It does not need to select lamps. There is no need to add compensation capacitors when connecting fluorescent lamps and energy-saving lamps, and there is no flicker phenomenon.

2. Lightning protection design, equipped with lightning protection function, safe and reliable performance.

3. One switch, multiple identifications. A multi-key remote control can centrally control the smart remote control switches of the whole family. The switch can learn to identify any remote control in the product. The switch and remote control do not need to be purchased together. Users can choose freely. Feel free to upgrade, add and configure yourself.

4. Easy to install, the standard 86-type wall switch has a standard appearance design, does not need to be connected to the neutral line, and does not need to change any accessories of the lamp. It can directly replace the original wall switch and can be installed by ordinary electricians.

5. Two-way control, which can be controlled by the wall or remote control. It can also be controlled by the touch screen wall remote control, which is more convenient to use.

6. Unique contact coding method, stronger anti-interference ability.

7. Ultra-low power consumption design, standby power consumption: less than 0.011W, calculated according to the formula of 1 kilowatt hour = 1 kilowatt hour: annual power consumption = (0.011W × 24 hours × 365 days) ÷ 1 kilowatt hour = 0.096 kilowatt hour electricity (less than 1 kilowatt hour in 10 years).

Purchase knowledge

1. Consult the certificate of the product

It doesn't matter if you can't tell the quality of the product. There are national & international certification agencies and testing agencies to help you distinguish the quality of the product. This is the easiest way. Products without certificate certification generally have no quality assurance, so I suggest that after you choose a product, you can first consult to see whether the product has passed the certification test? What certification tests have been passed?

2. Pay attention to the function & style of the touch switch when purchasing

When purchasing, pay attention to select applicable functions and styles. When choosing a touch switch, you should also pay attention to the function of the touch switch. According to the function, the touch switch is divided into: response speed, wet hand touch, dust-proof design, and power-off protection. Call protection. Smart energy-saving lamp. According to the standard style of the cassette corresponding to the switch, it is divided into type 86 and type 118. Among them, type 86 is our country’s standard.

3. Pay attention to the wiring method of the push button switch

This involves the wiring method of decoration. If you don't understand this, you will not be able to use it if you buy the wrong touch switch. Touch switches are divided into two styles: zero live wire and single live wire according to different wiring methods.
