In high-end appliances, touchable switches are often used. The principle of such switches is that many customers are curious, and what are the principles and characteristics of touch switches? Here is a detailed introduction to you.
Touch switches are widely used nowadays, not only using intelligence but also having high safety factor. Next, Xiaobian will introduce the touch switch principle and touch switch application.
Principle of touch switch
The rated voltage of the touch switch is the safe voltage of its normal operation. The rated current is the maximum safe current that can be allowed when the touch switch is energized. The insulation resistance is the resistance value of the touch switch conductor and the insulation part, and the insulation resistance value is higher than 100M Omega. The conventional requirement of contact resistance is less than 0.1-0.5 ohm, and the smaller the value, the better. Withstanding voltage is the maximum voltage that can be sustained between the conductor and the ground by the touch switch. When the touch switch is in service life, the number of times it can be used is about 5000-35000 times in the working environment of the inductive switch.
The working principle of touch switch is the infrared induction switch of human body, and the infrared sensing detection area opens the switch through touch. The touch induction switch has its special algorithm, which can effectively prevent the misoperation or connection of the key, and can directly use the power supply in the machine. The touch type key induction series has the function of active correction and compensation, which is very demanding for the production process. Capacitance is directly related to its sensitivity, but it will not be affected by ambient temperature when it is produced.
Features of touch switch function
The touch switch can control all the power switches in the room, the traditional switch can only control 1 or more than 5, and the touch switch can control twenty-seven channels at most. A touch switch is an intelligent switch that can show the current state of the lamp source, that is, it can be isomorphic touch switch panel to observe that the lamp is open or closed. In fact, the touch switch is not only controlled by the touch method, but also can be operated by the infrared remote control, so the user can use the infrared remote control switch in other rooms. Compared with the traditional switch, the touch switch also has the functions of power failure protection, memory storage and quick setting.
Touch switch application
The touch switch does not have any metal contacts in the structure, does not discharge and does not fire. It can not only save a lot of copper alloy but also effectively enhance the safety of the touch induction switch. With the advantages of excellent hand feeling, comfortable operation, precise control and no mechanical wear, it is widely used in consumer electronics, bathroom appliances, kitchen appliances, air conditioning and other household appliances, car burglar proof, LED applications, lighting lamps, mobile terminal tablets, audio, solar energy photoelectric applications, smart grid and so on.
