  • Publication number: 20140251774
    Abstract: An electrical wiring device includes dampening member placed in contact with a stationary contact. The dampening member absorbs and thus decreases at least a portion of the vibration that occurs in the stationary contact when it is impacted by a movable contact in the electrical wiring device. Thus, the noise associated with the impact is lessened. In certain exemplary embodiments, the dampening member is a bumper cap which partially encases a portion of the stationary contact. In certain exemplary embodiments, the dampening member is a bumper pad intimately disposed between an edge of the stationary contact and a wall of the housing, such that movement or vibration of the stationary contact is lessened.

  • Patent number: 8816229
    Abstract: An electric switch, in particular a rocker or toggle switch, includes a manually operable actuating part (12) that is mounted for rotary or swiveling motion and is deflectable from a neutral position to an actuating position. The electric switch further includes an electric switching member (16) that is adapted to be actuated mechanically, and an actuating member (22) that acts upon the switching member (16). The actuating member (22) is coupled to the actuating part (12) and to the switching member (16) such that a rotary or swiveling motion of the actuating part (12) from the neutral position to the actuating position is transformed into a substantially linear motion of the actuating member (22).

  • Patent number: 8735754
    Abstract: A power transfer switch in which a cross bar including a movable contact is rotated to come into contact with one of fixed contacts disposed on left and right sides of the cross bar. The cross bar has a non-circular cross-section including a protruded piece on left and right, and a rotating angle thereof is greater than a rotating allowable angle of the movable contact between the fixed contacts. A through hole into which the cross bar is inserted with play is formed on a base portion of the movable contact, and a step portion for receiving the protruded piece of the cross bar and a spring housing portion extended in a direction of a central axis of the movable contact are formed in the through hole. A compression spring is accommodated in the spring housing portion to cause the cross bar to elastically hold the movable contact.
