Abstract
The rear cover of a switch housing is removble and supports a plurality of individual switch units. Each switch unit has an axially positioned switch actuating plunger. The housing has a push-button mechanism positioned to contact the switch plungers. On the exterior of the switch unit are spring contacts which engage spring contacts on the housing. The housing has wiring connectors electrically connected to the housing spring contacts. By removal of the rear cover the switch units are withdrawn from the housing without the necessity for disconnecting the wires. The switch units and housing components can be stacked so as to increase the number of switches actuated by the push-button mechanism.
