    摘要： 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.

    摘要： A terminal structure includes a portion of a flexible printed circuit board and a plurality of metal terminals each consisting of a slender, elongate metal plate. The circuit board has a plurality of electrically conductive patterns provided on a resin film, a prescribed portion of the board having a connector insertion portion of a width substantially the same as that of an insertion hole of a connector. The plurality of metal terminals are placed in parallel on the flexible printed circuit board in such a manner that distal ends thereof are situated adjacent a distal end of the connector insertion portion, and each metal terminal is fixedly bonded to a respective one of the electrically conductive patterns provided on the flexible printed circuit board. The width of the connector insertion portion of the flexible printed circuit board to which the metal terminals have been attached is such that the connector insertion portion will not extend beyond the outer sides of the two outermost metal terminals on the longitudinal side edges of the connector insertion portion.

    摘要： A push-button switch keytop includes a flexible resin film deformed in such a manner that the resin film bulges upwardly to form a curved portion that is filled with a molding resin while the resin film is being deformed. The molding resin is allowed to harden to form a keytop body, whereby the top side of the keytop body consisting of the molding resin is integrated with the resin film in a state in which the top side of the keytop body is covered by the resin film. The keytop is manufactured by clamping a resin film between upper and lower molds, charging a molten resin from a pin gate provided on the lower mold into a cavity provided in the lower mold, thereby deforming and urging the resin film upward by pressure and heat produced by the molten resin and causing the resin film to adhere to the inner surface of the upper mold, filling the cavities of the upper and lower molds with the molten resin and separating the upper and lower molds after the resin hardens. An adhesive layer may be provided directly or indirectly via another printed layer on the underside of the resin film on that portion thereof where the keytop is located.
