Self generating switch is an improved technology inspired by RF control switch. RF switch is widely used in the field of control, because it does not need to be directly connected with the controlled equipment, so it has a wide range of applications. But because it needs to transmit wireless signals, the switch itself needs power. In essence, it does not reduce the complexity of power transmission system. The same problem also appears in many Internet of things devices. In this case, people will naturally find various ways to realize self generation of terminals. The environmental back reflection technology mentioned earlier solves this problem, which is to obtain energy directly from electromagnetic waves, while this switch collects energy from the kinetic energy generated by the push of the switch. Specifically speaking, it supplies power to the components that transmit RF signals through the principle of electromagnetic induction.

The core of the switch is the energy collection device composed of the bistable permanent magnet mechanism or the reluctance stepping motor, which realizes the RF switch control system without battery and mains power at the RF transmitter. Four commands of "on", "off", "increase" and "decrease" can be provided (the latter two commands can only be realized by the energy collection device composed of the reluctance stepping motor). Therefore, the switch and dimming function of LED lighting can be realized, and it can also be applied to access control system. Because of its simple structure and low power consumption, the RF transmitting unit, which is the switch control part, can provide enough current to drive it to send commands at the moment of pressing the switch.
