ABSTRACT:
An electric appliance protection apparatus is provided including a housing having a socket formed therein in coplanar relationship therewith. The socket is provided for removably receiving a plug of an appliance. A plurality of prongs are mounted on the housing which define a plug for being removably inserted within a conventional alternating current receptacle. Three wires are situated within the interior space of the housing and connected between the socket and the prongs thereof. The wires include a hot wire, a neutral line, and a ground line. Finally, a control mechanism has a deactuated mode wherein power transfer between the socket and prongs of the housing is precluded and an actuated mode wherein power transfer between the socket and prongs of the housing is permitted only upon the depression of momentary switch while power is available from the conventional power source. It should be noted that the control mechanism remains in the actuated mode only during the continued receipt of power from the conventional power source.
