Breaker switch includes connector, socket, and surrounding housings. The connector housing has contacts and a blocking lever. The socket housing has sockets and a gear rack. An operating lever has a gear mounted to the connector housing and engaged to the gear rack to mount the connector and socket housings such that the connector housing is movable relative to the socket housing between starting and final positions. In the starting position the connector and socket housings disengage such that the contacts and sockets disengage. In the final position the connector and socket housings engage such that the contacts and sockets engage. In the starting and final positions the blocking lever engages the gear to maintain the position of the connector housing. The surrounding housing is connected to the socket housing and has a control edge that releases the blocking lever from the gear to enable the connector housing to move.
