Abstract

Abstract An improved switch actuating apparatus operating dome switches in which a dome shaped switching member mounted on a circuit board is actuated by the action of an elongated button member urged in a linear direction or a pivotal direction into contact with the dome switching member against the action of a elastomeric member positioned between the elongated button member and dome switching member. The elastomeric member has an aperture formed therein through which a tip portion of the button member extends for contact with the dome switching member. The button member has a plurality of vertically extending leg members which are received through openings in the circuit board. The leg members each have a hook portion extending from the end thereof to effect the desired operation of the switching member through either a pushing or rocking action by an operator.
