Wireless Switch is a wireless radio transmitter without being connected with any control circuit or battery, which plays its role by matching with a wireless receiver. It can control the receiver, therefore it can remote-control the load (lights, fan, etc.) connected with the receiver.
The innovative self-powered technology is used as a self-powered wireless switch, which can harvest the energy caused by the finger's pressing to send the radio signal. Therefore, the battery is not required, which can avoid the trouble of changing the battery and protect the environment.
