Abstract

A recognition switch assembly (10) has a movable contact assembly (24) mounted on an actuator (22) mounted for sliding movement along a longitudinal direction (12a) in a housing (20) with a stationary contact board (26) mounted on the housing over the movable contact assembly (24). The actuator is formed with a laterally deflectable beam (22q) on one side of the actuator having a protrusion (22s) which cooperates with space protrusions (22p) on the opposed side for sliding engagement with opposed sidewalls (20f, 20g) of the housing. A pair of vertically deflectable beams (22k) having a protrusion (22n) slidingly engage platform surfaces (20b, 20c). When mounted in the housing, the beams are deformed to eliminate clearances between the actuator (22) and the housing (20) in both the vertical and lateral directions resulting in an improved, vibration independent, electrical output signal of the switch assembly.
