ABSTRACT:
The keytop of a push-button switch includes a keytop portion situated on the top of a resin film, and a retaining portion situated on the underside of the resin film. The keytop portion and retaining portion are formed into a unitary body by a resin-molding process in which resin is passed through a hole provided in the resin film such that the resin film is sandwiched between the keytop portion and the retaining portion. In another embodiment, the retaining portion is loop-shaped and is formed into a unitary body with the keytop portion by a resin-molding process in which the resin passes through a plurality of holes provided in the resin film in a pattern corresponding to the loop-shaped circumference of the retaining portion. The resin film is sandwiched in a water-tight state between the keytop portion and the loop-shaped retaining portion.
