The self generating switch does not need to connect wires or install batteries. It collects energy by the built-in micro energy motor, converts the mechanical kinetic energy into electrical energy when the finger presses the switch, and sends out signal command to control the on and off of the electric lamp. Using digital radio frequency modulation to control the light on and off, it can work once and for all without connecting wires or installing batteries. Because there is a micro energy collection generator in its internal device, when the switch panel is pressed by hand, the generator will generate energy to provide power for the radio transmitter. Only when you press the key with your hand, it will work without electricity. It is usually in a static state and does not consume any energy. There is no binding of wires and batteries, no restriction of hands-on ability, no need to dig holes in the wall, no need to lay pipes and thread; no electricity is free, just install as you like.
