Abstract: An electro-mechanical switch includes multiple switch modules carried within a housing with preselected switch modules slidably mounted within pockets and positioned for activation by a shaft key during rotation of the shaft for causing the switch module to be displaced within the pocket for biasing an activation button against a housing surface. A push-pull operation of the switch causes a disk carried by the shaft to activate buttons of fixed switch modules. The disk includes apertures aligned for activating preselected buttons.

Abstract: An electromechanical switch operable with systems for controlling and monitoring vehicular traffic includes switch modules carried within a housing for mounting on a system control panel. Selected switch modules are slidable mounted within pockets and positioned for operation with a shaft that is rotatable and slidable in a push-pull fashion for displacing a preselected module for movement thereof and activation of a switch module button by causing the module to be moved from a neutral position to a button operating position which presses the button against a stop for activation of the switch module. The shaft is suitably mounted for rotation within the housing about a longitudinal axis and is operable for activating the selected switch modules by a pushing/pulling movement and a rotational movement of the shaft by a user for activating one or a combination of switch modules.
