ABSTRACT OF THE DISCLOSURE Disclosed is an interlocking mechanism for a switched socket outlet having a manually-actuatable switch and a socket for accepting a plug having an external key. The mechanism has an interlock member displaceable by operation of the switch between a switch-open position and a switch- closed position, and a pin movable by the key upon insertion of the plug into the socket. In the switch-open position, the interlock member allows the plug to be inserted and move the pin from an extended position wherein it prevents attempted closure of the switch by obstructing displacement of the interlock member to the switch-closed position, to a retracted position in which the pin allows such movement of the interlock member. The interlock member may be so arranged as, when in the switch-closed position, to obstruct the return path of the key to prevent attempted withdrawal of the plug from the socket while the latter is electrified. The key on the plug also prevents the displacement of the interlock member from the switch-open position until the plug is fully inserted in the outlet.
