The principle of touching the switch is that the capacitor or resistance fluctuation generated by the part of the human body (such as the finger) is close to the switch, and the command is transmitted to the chip, and the switch circuit is controlled by the chip to realize the purpose of opening or closing the electrical appliance. In the process of switching electrical appliances, the human body does not need to contact close contact with high-voltage power sources. Choose the touch switch, please consider the following points, hope to help you!
< br >
1, choose the product with isolation circuit design, this design of the circuit, effectively separate the high-voltage power supply and low-voltage power supply, there is no risk of leakage when touching.
< br >
2, choose products that can effectively turn off low-power LED lights and fluorescent lamps, so as to ensure that the touch switch can turn off all kinds of lamps.
< br >
3, choose a wide voltage design products, because the domestic electricity voltage is fluctuating, very stable fluctuations between a few volts to 10 volts, unstable tens of volts to hundreds of volts. Therefore, products with wide voltage design can be well adapted to various electrical environments.
< br >
4, choose low-temperature and low-power products. Touch switch is to be electromechanical flow, the lower the standby current, the less power consumption, the more energy-saving products. Now products generally do not consume one degree of electricity for 2 years. Relatively speaking, the lower the temperature when the product is working, the more stable the performance and the longer the service life.
< br >
5, choose products with good sensitivity, touch the sensitivity of the switch, directly affect the user experience. Some products touch a few times can not turn on the light or turn off the light, so the use of the feeling is not good.
< br >
6, choose capacitive touch and space touch products, such products are relatively easy to operate, even if there is water on the hand can effectively touch control. There's love, there's home, there's Kuntai! Source Peak Kuntai Technology (SOVXA)
