Abstract
First and second switch blocks comprising a plurality of first and second push button switches respectively are connected together in parallelism and in mirror symmetry and are provided with first and second latch bars common to the first and second switches respectively. The switch blocks are held together by detachable connectors which, in turn, support pivotal levers. The levers engage the ends of the switch block latch bars and cause interlocking of any pushbutton switch or switches in the depressed position and unlatch any previously depressed pushbutton switch or switches in either the first or second switch blocks.
