Power line socket control using radio receiver - which is placed near special socket outlet, different from standard outlets, and is plugged in as load control

摘要

An audio frequency power line carrier control receiver (3) is installed near the point of the load (6) connection, and controls an allocated socket-outlet (4) specially designed for it with an earthing contact. The plug (5) fitting into the socket-outlet and permanently attached to the load (6) will not fit into an ordinary three-pin socket-outlet. As it has a square section fitting instead of the normal round section fitting for the normal load.
