    Abstract: An appliance switching system is used in combination with a duplex electric outlet having a first receptacle that is constantly energized and a second receptacle that is selectively energized and de-energized by operation of a wall switch. The system includes first and second plugs for electrically engaging the respective receptacles. A selectively energized electrical socket is connected to the first plug. A three-way switch assembly is connected between the first plug and the socket and is alternatable between opened and closed states. A pair of relays are responsive to operation of the wall switch and the actuator switch respectively for independently opening and closing the three-way switch assembly to respectively energize and de-energize the socket.
