  • Publication number: 20150179367
    Abstract: A manufacturing method for a switch includes steps of: arranging a plurality of fixed electrodes so as to be supported by a plurality of pins provided within a metal mold; molding a switch case integrally with the fixed electrodes by injecting a first resin into the metal mold; pulling out the pins to take out the switch case from the metal mold; filling a liquid-state second resin into through holes formed in the switch case as traces of removal of the pins; and curing the liquid-state second resin to form a protection portion.

  • Publication number: 20140311882
    Abstract: A switch includes an insulating case, a fixed electrode and a movable electrode. The insulating case is formed with an operating space therein. At least a part of the fixed electrode is disposed in the operating space. The movable electrode is disposed in the operating space, and is configured to be engaged with and disengaged from the part of the fixed electrode. A flat surface of the insulating case and a flat surface of the fixed electrode, which are located in outermost positions in a predetermined side of the insulating case, form a plane in corporation with each other.

  • Patent number: 8835788
    Abstract: A slide switch includes a housing, a plurality of fixed electrodes, and a slider. The housing includes a first face provided with an accommodating recessed part and a second face configured to be attached to an attaching board. The fixed electrodes are provided in the accommodating recessed part. Each of the fixed electrodes has an external terminal exposed on the second face. The slider has a movable electrode configured to be electrically conducted to the fixed electrodes, and is movably provided in the accommodating recessed part so as to switch an electrical conducted state of the movable electrode and the fixed electrodes.

  • Publication number: 20120048707
    Abstract: A tactile switch includes a base, an elastic conductive member, and a cover sheet. A fixed contact is provided in the base. The elastic conductive member, has a dome shape, opposes the fixed contact, and is elastically deformed to be electrically conducted with the fixed contact. The cover sheet covers the elastic conductive member. An operating protrusion is provided on a face of the cover sheet at a position corresponding to the fixed contact. The operating protrusion includes an end part, a root part of fixed to the cover sheet and having a diameter larger than a diameter of the end part, and a bent part connecting the end part to the root part so that a first angle formed by a side wall of the root part with respect to the face of the cover sheet is smaller than a supplementary angle of a second angle formed by a side wall of the end part with respect to the face of the cover sheet.

  • Patent number: 8091212
    Abstract: A method of manufacturing a panel switch is provided. The panel switch includes insulating films and a base layer having a stationary contact. Each insulating film includes an adhesive layer, and an apex portion of a moving contact adhered to the adhesive layer. The insulating films are aligned and adhered on top of each other and the adhered insulating films are aligned and adhered to the base layer such that the locations of the moving contacts of the respective insulating films align with the stationary contact of the base layer. The method includes applying an adhesive layer to an insulating film; adhering a moving contact onto the adhesive layer; aligning the moving contact with a stationary contact of a base member and adhering the insulating film to the base member; and cutting and removing an excess portion from the insulating film with a laser.
