The Self-Powered Wireless Switch (433Mhz) sends signals wirelessly without installing a battery. The switch is composed of a micro-generator and a 433Mhz radio frequency circuit. Based on the principle of electromagnetic induction, the micro generator converts the kinetic energy of the press into electrical energy that will be rectified and stored by the RF circuit later, by which a signal can be transmitted wirelessly.

It is suitable as a maintenance-free switch for long-term monitoring of changes in the state of pressing, collision, etc., such as making wireless doorbells, pagers, food ordering devices, wall switches, etc.
