ABSTRACT A plug (10) carries terminals (38) which also act as switch contacts and which insert into a receptacle (12) with essentially zero insertion force. The receptacle also carries terminals (84) which similarity double as switch contacts. After insertion of the plug into the receptacle, the plug terminals and receptacle terminals are electrically bridged by electrical bridges (68) driven forward by actuator means (62, 122) which also doubles as an integral part of an interlock arrangement. A first bayonet type of polarizing means ensures that the plug will only insert into the receptacle in a single oriental lion, whereas a second polarizing means permits keying a given plug to a given receptacle. The combining of switch and interlock into a minimum of parts provides simplicity and interlock protection as well as creates an exceptionally compact design.
