ABSTRACT:
A membrane switch having mounting means for mounting the switch to a cathode ray tube (CRT) is disclosed. The mounting means is comprised of extensions protruding from the perimeter of the membrane switch, each extension having thereon a patch of a coupled fastening assembly. The fastening assembly is comprised of two separable parts, the inner surfaces of which have a very large number of closely spaced hooking elements of the hook and loop type that engage with each other when the two parts are pressed together. When the switch is aligned against the CRT, the extensions wrap around the perimeter of the CRT. The outer surface of the fastening assembly can then be attached to the sides of the CRT. The mounting means disclosed herein holds the switch securely to the face of the CRT and at the same time permits easy realignment if the switch becomes distorted during use.
