Wireless, battery-less pushbuttons enable the remote control of a relay (receiver) by means of a pushbutton (transmitter). The control is by radio transmission, where the transmitter is fitted with a “dynamo”-type generator that converts mechanical energy—produced when the pushbutton is pressed—to electrical energy. A radio-encoded message with a unique ID code is sent as a single pulse to one or more receivers located up to several dozen meters away.
