  • Patent number: 8692633
    Abstract: A switch is provided with a reset function including a heart cam portion which extends from a locked position to a side where a lock pin operation end biases, and a lock release passage IV which is blocked off by a lock pin retention protrusion during being retained. The lock pin retention protrusion is moved by biasing force of the lock pin operation end so that the locked state is released by opening the lock release passage IV. This embodiment can decrease wear between the lock pin and the member for retaining the lock pin.

  • Patent number: 8558131
    Abstract: A switch has a base, a housing, a support terminal that is assembled in the base, a moving contact piece that is made of a band-shaped material having a section being formed into a substantial J-shape, a moving contact being provided in one end portion of the moving contact piece, an intermediate portion of the moving contact piece being turnably supported by a turning bracket of the support terminal, a plunger that is accommodated in an internal space while being vertically movable, wherein the internal space is formed by fitting the housing in the base, and a coil spring that is turnably supported by the plunger. The plunger is vertically moved such that one end portion of the coil spring is slid while brought into press-contact with an edge of the other end portion of the moving contact piece, whereby the moving contact piece is inverted to bring and separate the moving contact into contact with and from a fixed contact.

  • Patent number: 8169282
    Abstract: A switch and an electronic device maintain a power supply ON state until data processing is completed, and automatically turn OFF the power supply after the data processing is completed. The switch includes a rotation operating body that does not receive an operation force from an operating element when OFF operated is arranged inside the operating element. The rotation operating body includes a switch operating portion for turning ON a power supply switch mechanism and a return spring regulating piece for biasing a return spring in an anti-biasing direction. A regulating state of the return spring regulated by the return spring regulating piece is held, where the ON state of the power supply switch mechanism is held with a permanent magnet, and the ON state of the power supply switch mechanism is released by applying a release force on the permanent magnet when the power supply is reset.

  • Patent number: 8134095
    Abstract: A switch has a supporting terminal assembled to a base, a movable contact piece, made of a band-shaped conductive material bent to a substantially J-shaped cross section, having a movable contact at one end and having an intermediate portion rotatably supported by a rotation receiving portion of the supporting terminal, a plunger accommodated so as to be movable up and down in an internal space formed by fitting a housing to the base, and a coil spring including a forced dissociation bent portion at one end and being rotatably supported by the plunger. The plunger is moved up and down to slidably move one end of the coil spring while pressure contacting the other end edge of the movable contact piece to invert the movable contact piece and contact or separate the movable contact to and from a fixed contact, and to lock a distal end of the forced dissociation bent portion to the other end edge of the movable contact piece and exert a shear force on the movable contact of the movable contact piece.

  • Patent number: 8017883
    Abstract: A switch includes a base, a support terminal assembled in the base, a movable contact piece made of a belt-like electroconductive material bent into a substantial J-shape in section, a plunger vertically movably accommodated in an internal space, and a coil spring turnably supported by the plunger. The movable contact piece includes a movable contact provided in one end portion thereof. An intermediate portion of the movable contact piece is turnably supported by a turning support portion of the support terminal. The internal space is formed by fitting a housing in the base. The plunger is slid while vertically moved press-contact one end portion of the coil spring against the other end edge portion of the movable contact piece such that the movable contact piece is reversed to bring the movable contact into contact with a fixed contact or to separate the movable contact from the fixed contact.

  • Patent number: 7919735
    Abstract: In fabricating a door switch for a microwave oven, two switches are incorporated in a single switch case to allow a reduction in the size and to allow common use of switch components, thereby achieving a cost reduction through a reduction in the number of components. Further, a contact switching structure tilted in conjunction with opening and closing of a door is provided to achieve high accuracy in switching the switches. There is provided a first switch whose contact portions are switched by elastically displacing a conductive contact piece in the switch case when a first tilting lever is tilted, a second switch whose contact portions are switched by elastically displacing another conductive contact piece in the switch case at timing that is slightly different from the timing for switching the contact portions of the first switch, and a third switch which is switched when a second tilting lever is tilted.

  • Publication number: 20080099320
    Abstract: A low-cost switch includes a base, an operation lever, a movable contact piece, and a coil spring. In the base, fixed contact terminals are insert-molded, and fixed contact portions of the fixed contact terminals are exposed in a concentric manner to an upper surface. The operation lever is turnably supported along an upper surface of the base. The movable contact piece which is formed by a rod-shape conductive spring member, and the movable contact portions at both ends of the movable contact piece are slidably disposed to the fixed contact portions. The coil spring latches an arm portion on one end side to the upper surface of the base while latching an arm portion on the other end side to the operation lever, the coil spring imparts a contact force and a returning force.
