Abstract

Abstract A sealed backlit switch assembly including an integral body composed of an elastomeric material and having a hollow push button. The body is clamped to a panel by means of a printed circuit board and threaded fasteners whereby the body is sealed to the panel. The printed circuit board has an LED mounted thereon which is enclosed in a hollow push button which forms a part of the unitary molded body and thereby illustrates the push button.
