Abstract
A low profile, lighted, push button switch including a printed wiring board having conductors terminating in switch contacts thereon. A first insulative member abuts the wiring board covering the conductors thereon and has an opening therein which exposes the switch contacts. A resilient switch element is positioned in the opening in the first insulative member cooperating with the switch contacts and actuatable between open and closed positions in response to force applied thereto. A thin sheet of insulating material covers the first insulative member extending over the opening and the switch element therein. A second insulative member abuts the insulating sheet and has an opening therein aligned with the opening in the first insulative member. A switch actuating member is positioned in the opening in the second insulative member. Another printed wiring board abuts the second insulative member and has at least one opening therein communicating with the opening in the second insulative member. A light source, such a light emitting diode, is carried on the other printed wiring board and is adapted to be energized by conductors thereon. A third insulative member abuts the other print…
