A patch module is disclosed, into which a plug can be easily inserted. In the preferred embodiment, the patch module has two sets of receptacles, the first set having three receptacles and the second set having two receptacles. Both sets are mounted on a printed circuit board which makes the desired electrical connections. The first receptacle of the first set is permanently connected to the first receptacle of the second set. The second receptacle of the first set is permanently connected to the second receptacle of the second set. The conductors of the first and second receptacles of the second set are normally connected together by contacts on a spring-biased, slidable panel, the panel being mounted for movement along the circuit board. When a plug is inserted into one of the first two receptacles of the first set, the panel slides to its other position, breaking the connection between the first and second receptacles of the second set. The panel slides in a direction generally perpendicular to that of the plug, through the cam action of a tab which is pushed by the plug. While being inserted, the plug travels a greater distance than the distance traveled by the panel, thus creating a mechanical advantage. The plug can easily be inserted against the spring force, and a simple latch is sufficient to insure that the spring-biased panel will not push the plug out of its socket.
