International Classification:

H01H 928

US Classification:

200 44

Abstract:

A controlled access socket assembly wherein a locking device prevents unauthorized movement of the actuator of an electric switch that selectively connects and disconnects a source of electrical power to an electrical outlet socket adapted to receive the male plug of an electric power cord. A plug holding device is movable between positions that selectively holds and releases a power cord plug from being held in the socket. A cam is operatively associated with the switch actuator to urge the holding device to its holding position when the latter is in its plug-releasing position when the actuator is moved to cause deenergization of the socket, with the cam preventing movement of the holding device to its releasing position solely when the switch actuator has been moved to cause deenergization of the socket.
