Abstract
A keyboard has first and second nested planar members with depressions formed thereon. The upper member is transparent. The lower member may be color coded and carry replaceable key indicia in the depressions. The laminated overlay nested planar members are disposed adjacent to a conventional elastomeric diaphragm switch assembly having an upper layer of shaped protrusions abutting the lower most inner surfaces of the second or lower member depressions. Frame structure of variable form assists in retaining the laminated overlay members in fixed relationship to the elastomeric diaphragm switch assembly.
