  • Patent number: 7744272
    Abstract: A portable apparatus has a push button mounted on a casing for operating a contact inside the casing. The push button is axially slidable in a pipe fixed in a through-hole extending through the casing. A coil spring encircles the pipe and is interposed between a flange of the pipe and a head of the push button to urge the push button outwardly. A packing ring for sealing the space between the pipe and push button is attached to either the pipe or the push button in the region where the coil spring encircles the pipe. Since the coil spring overlaps the packing ring, the axial length of the pipe and push button can be shortened to reduce the size of the casing.

  • Patent number: 7735214
    Abstract: A metallic thin plate is etched to form a plurality of keypads having hollowed portions and cut to form a metallic keypad panel having a predetermined shape. Then, an electroplated layer is coated on the surface of the metallic keypad panel. A layer of protective film is adhered on the non-electroplated surface of the metallic keypad panel, which is disposed in a mold. A plastic material is then injected into the mold, so that the plastic material is formed into a pattern layer. In addition, a plastic thin plate is prepared with one side surface printed with a displaying layer, is adhered on elastic bodies having a plurality of protrusions and is cut to form an elastic layer. Finally, after the protective film is peeled off, an adhesive layer is applied thereon. The elastic layer is adhered on the surface of the adhesive layer.

  • Publication number: 20100072046
    Abstract: A waterproof push button switch does not need to be covered with a resin to a height at which a divided connected portion of a case for the switch is hidden by the resin in a height direction and the divided connected portion may be waterproofed. A gap (55, 57) is formed between a peripheral wall portion 7b of a base case 7 and a second cylindrical wall portion 9b of a cover case 9, and between an opposite surface 41 of the cover case 9 and a waterproofing seal member 11. The gap (55, 57) extends from an opening portion of the base case fitting chamber 37 to an annular watertight seal portion 51 to completely surround a periphery of the watertight seal portion 51. The thickness of the gap portion 55 is determined so that the resin entered into the gap portion 55 from an opening portion 37a of the base case fitting chamber 37 reaches the watertight seal portion 51 by surface tension.
