Wireless remote control arrangement, e.g. for domestic appliances, uses mobile phone radio signal and receiver with time delay-actuated relay to switch loads

摘要

A wireless control system has a receiver that switches electrical apparatus using pulses generated on reception of a radio signal from a mobile phone or other transmitter with the switch then locked by a time delay. The receiver is designed to receive local signals only and may comprise a resonant circuit or resonator with a diode.
