ABSTRACT:
A switch actuating assembly for a keyboard switch comprises a frame and plunger slideably mounted on the frame. The plunger has an integral deflectable camming arm extending parallel to the frame from its upper end. The camming arm engages a cam on the frame during depression of the plunger to provide tactile effect when the switch is closed. The plunger can be assembled to the frame in any one of three orientations to provide the tactile effect, to provide a shift locking effect, or to permit closing of the switch without tactile effect.
