ABSTRACT OF THE DISCLOSURE A push button switch provides a visual switch actuation acknowledgement signal when actuated. The switch includes an end ring which extends through a cover plate. A push button extends into the end ring and has a lens cap which is exposed to a switch operator at a front surface of the cover plate. The push button also has a plurality of plungers which extend rearwardly through an adapter to actuate an electrical switch mounted on a switch block. The end ring, the push button, the adapter and the switch block are retained on a pair of studs extending from a rear surface of the cover plate by a pair of nuts. A light reflector is positioned between the push button and the adapter and has a forward reflector portion and a smaller diameter rearward baseportion which form a radially extending shoulder. The base portion is inserted into an opening in the adapter and is mounted on the adapter by contact with the shoulder. A printed circuit board having light emitting diodes and a diode rectifier bridge mounted thereon is retained in a recess formed in the base portion of the light reflector. A pair of wires connected to the printed circuit board connect the bridge rectifier to a power supply. 11
