One type of button switch of family lighting often has a indicator light.这种指示灯的电阻极大，使电路中的电流极小，从而使在夜晚用电器的电压达不到额定电压而不能亮，一般情况下这种指示灯内有一个电容，因为一个小小The indicator light cannot accommodate the voltage of 220V.

This is the Huiyi we only know. Since 1986, Huayi has continuously brought us innovation and surprises.A series of accessories and light sources are the objects of Huayi research and innovation.
Indicator light resistance
The resistance is the most used in all electronic products.The main role of resistance is to change the mild power of the power and make the power energy become a thermal energy. It is an energy consumption element.The circuit usually plays the role of separatism. AC signals and DC signals can pass the resistance. The multimeter can determine the quality of the resistor and the resistance value of the resistance.But when judging the resistor, you should pay attention to the hand cannot be touched.The resistance is generally not damaged during use, but it should be noted that the resistance is virtual welding and welding.
Indicator light model
There are also many models of indicator lights. The first brand is good. The model AD16-22DS, one of 3.12 yuan.The second brand is MyCN, the model AD16-22DS, 1.5 yuan a.The third brand is TNTAI, and the model is AD11-22/2141, 2 yuan, and 2 yuan.
