  • Patent number: 9431193
    Abstract: A low current switch has a flexible movable contact that can be deflected by an actuator. In some implementations the switch may permit a low current switch to be manufactured using elements of a high current switch without requiring large amounts of precious metal. The flexible movable contact may be arranged as one or more cantilevers that are deflected using a rocking actuator. The actuator interacts with the movable contact in such a way as to provide tactile feedback to an operator comparable to a high current switch having a rigid movable contact. Also described are a set of low and high current switches, components of a low current switch, and a method of manufacturing a low current switch.

    Abstract: A switch assembly includes an actuator assembly having a slidably supported pushbutton and a switch mechanism switchable between alternate positions. The pushbutton is biased by a return spring between the pushbutton and a retainer. A pin is received within the return spring coils and engages a pivot member through an elongated opening in the retainer that allows lateral pin movement. A switch plate moves between alternate positions by contact with the pivot member and is maintained in one of the positions by a contact spring between the pivot member and plate. A spring damper in the contact spring coils limits resonating vibration. The switch assembly provides a multiple segment force input profile having first and second segments leading to the switching force with slopes according to a preferred ratio. Third and fourth segments of the input profile following the switching force define a V-shape.

  • Patent number: 6459060
    Abstract: An electric rocker switch is disclosed having a gull wing shaped rocking contact. The rocking contact pivots on a center terminal between a pair of upright blades. A centering protrusion disposed on a lower surface of the rocking contact rests between the uprights blades of the center terminal when the rocking contact is in a center position, thus preventing lateral movement of the rocking contact beyond the limits of the upright blades. First and second rocker contacts are located on opposite sides of the rocking contact. The first and second rocker contacts face toward first and second fixed contacts, respectively. Thus, the first rocker contact touches the first fixed contact when the rocking contact rocks to one side and the second rocker contact touches the second fixed contact when the rocking contact rocks to the other side. Positioning surfaces and top inside edges of the upright blades serve as pivots for the rocking contact as it rocks from side to side.

  • Patent number: 6291784
    Abstract: A compact snap switch that can be assembled mechanically and is equipped as a microswitch. The switch includes a housing for the microswitch and consists of two asymmetrically divided halves whose cut site runs along the edge of one of the large side surfaces. Thus a comparatively large assembly window and a favorable assembly direction are obtained due to the few undercuts of the components. In addition, due to the minor modifications of the machine-instrumented components, the switch can be easily modified for the different application formats. A movable contact lever with a moving contact is mounted so as to pivot in a knife-edge bearing. The free end of the contact lever has a wedge profile which with one of its two sides is exposed to a switching roller reloaded by a switching spring. Switching roller and switching spring are seated in a switching member which is movable along a straight path and abutted by a restoring towards an idle position.

    Abstract: Disclosed is an improved switch structure having forcedly opening-and-locking mechanism installed therein. It is responsive to the sticking of the movable and stationary contact elements for forcedly breaking an associated heavy-current carrying circuit which otherwise, would remain closed through the stuck contact elements. The forcedly opening-and-locking mechanism comprises an auxiliary contact section spring-biased to retain the stationary contact element in conductive condition to the associated circuit. It is responsive to the sticking-and-rising of the movable and stationary contact elements for allowing the stationary contact element to be apart from the conductive position to the associated circuit by yielding the rising force of the stuck contact elements until the locking position is reached, in which position the stationary contact element is kept in non-conductive position.
