ABSTRACT:
A replacement cover plate for a conventional wall outlet is disclosed, the cover plate being modified to include pivoted release plates disposed over each plug receptacle. Each release plate is conformed to the plan form of the receptacle itself and includes in the face thereof the necessary openings for receiving the terminals of a plug. Formed on the wall plate, adjacent to one edge of each receptacle are two opposed tabs adapted to receive a cylindrical fulcrum extending from the adjacent surface of the corresponding release plate. Extending from each release plate, distal of the fulcrum, is a cantelevered, raised projection or lever which when manually depressed will pivot the release plate away from the adjacent receptacle. Thus a plug inserted through the openings in the release plate and received in the receptacle will be withdrawn out of the receptacle by the articulation of the release plate.
