  • Patent number: 8410381
    Abstract: A high waterproof compact push-on switch includes a first contact plate, a spacer, and a second contact plate laminated in this order. The first contact plate is substantially rectangular, and made of highly conductive flat sheet metal. The spacer is flat, rectangular, made of LCP resin, and has a circular center hole at its center. The second contact plate is substantially rectangular, made of highly conductive flat sheet metal, and has a circular central opening at its center. The spacer is thermocompression-bonded to the surfaces of the first and second contact plates so as to integrate them. On the second contact plate is provided a dome-shaped movable contact, which is covered with an adhesive protective sheet.

  • Patent number: 8022326
    Abstract: A push switch includes an upper movable contact, a lower movable contact, a center fixed contact, an intermediate fixed contact, and a peripheral fixed contact. The lower movable contact includes an annular portion, and four legs extending from the annular portion. One of the four legs is placed on a peripheral fixed contact. The upper movable contact faces the center fixed contact through a circular hole in the annular portion of the lower movable contact via a space between the upper movable contact and the center fixed contact. Two legs out of the four legs are located away from each other by an angular interval smaller than 90 degrees with respect to the center of the annular portion. Upon being pressed, the actuator activates two combinations of switch contacts, one combination including the movable contacts and the intermediate fixed contact and the other combination including the movable contacts and the center fixed contact, providing the push switch with a small size.

  • Patent number: 7906741
    Abstract: A configuration of a push switch minimizes the extent to which the switch protrudes from a wiring board, and thereby allows for a device including the switch to have smaller dimensions. Minimizing the height by which the switch protrudes above the wiring board also minimizes the moment caused by the pressing the switch which is transferred to terminals soldered to the wiring board, and thus improves the mechanical strength of the attachment to the wiring board. The configuration includes, in part, a case having a terminal protruding therefrom, wherein a lower surface position of the terminal where soldering is performed is located above a bottom surface of the case.

  • Patent number: 7816615
    Abstract: A push switch includes a movable contact, and a drive body. The movable contact includes an annular part with a circular central hole and four leg parts inclined and extruded downward from the outer circumferential end of the annular part by way of a deflection part, formed in a shape bulging upward at the circular central hole side. The drive body includes a flat plate with the lower end abutting against the position of the inner side of the deflection part of the movable contact, and an operation part of a smaller diameter than the abutting position provided on the flat plate, if the operation part is pressed and manipulated at a position remote from the center, a light and responsive click feel is obtained.

  • Publication number: 20100230267
    Abstract: A push switch includes: an operation portion which is pushed and operated from a direction parallel to a surface of the mounted printed circuit board; a plurality of contacts which are electrically conducted to each other by the push operation of the operation portion; a case which is formed from an insulation body and has a lower surface facing the printed circuit board; a plurality of terminals which are led out from the case to outside; and a embedded portion which is physically and electrically connected to any one of the terminals and embedded and fixed inside the case. An exposed portion is formed in a part of the embedded portion so as to be exposed to the outside from the lower surface of the case. Soldering strength is improved without increasing an occupied area of the push switch on the printed circuit board.

  • Publication number: 20100089733
    Abstract: In a case provided with a central fixed contact and an outer fixed contact on an inner bottom surface of an open-top concave section, a terminal connected to each of the fixed contacts is disposed at a position above a bottom surface of the case. The inner bottom surface of the concave section of the case is disposed below a lower surface position of the terminal. It is thereby possible to suppress a height of a push switch from a wiring board, the push switch being provided with mechanical strength and used for input operating sections or the like of a variety of electronic devices.
