(57) A transparent membrane switch assembly (10) and mounting means (118) for mounting
the assembly (10) to a cathode ray tube (CRT) (68) are disclosed. The assembly (10,
10') is comprised of two layers (12, 16) of transparent film having spaced-apart parallel
double fineline conductors (20) deposited on the internal surfaces (14, 18) of both
layers (12, 16). The mounting means (118) comprise extension (114) protruding from
the perimeter (116) of at least one of the layers of film, and a patch of a coupled
fastening assembly (120) attached to each extension (114). Each fastening assembly
comprises two separable parts, an outer surface (124) of one part being attachable
to a side surface of a CRT when the switch assembly is registered with the CRT face.
