Control circuit for turning a device on or off using a conventional wall switch or a device switch

Apparatus for controlling the energization of an electrically operated device from a conventional wall outlet consisting of first and second female outlet sockets, said first female socket being connected to receive continuous alternating current power from an available power source and said second female socket being connected to receive switched alternating current power from said source via said household wall switch, said apparatus comprising, in combination:

• a first adapter including first and second male input plugs adapted for insertion into first and second female outlet sockets respectively, said adapter further including a third female outlet socket for receiving a third male plug connected to one end of a two wire power line for continuously supplying electrical power to said device from said first female socket, said first adapter further including means for applying a control voltage to said two wire power line when said second socket receives switched power from said source, and
• a second adapter comprising, in combination,
• a manually operated device switch,
• an electrically operated switch for connecting and disconnecting said electrically operated device and said two wire power line, and
• a control circuit for actuating said electrically operated switch in response to both said control voltage received via said two wire power line and to the actuation of said manually operated switch.
