  • Patent number: 7700888
    Abstract: There is disclosed structure which overcomes the deficiencies with respect to prior art devices by providing a wiring device such as a switch having a paddle that pivots about its upper end and is biased to assume the same at rest position when either in its on position or off position. Repeated pressing and releasing the lower portion of the face of the switch paddle alternately closes and opens a set of contacts within the switch to alternately connect and disconnect a load form a source of electricity each time the paddle is pressed. Thus, regardless of whether adjacent switches are on-off switches or 3-way switches, they will always be in alignment. An on-off indicator such as a small light is provided to indicate to a user when the contacts of the switch are opened or closed. The paddle of the switch has a length-width ratio dimension that is proportioned to provide a finger contact surface of increased area to allow a user to more easily and quickly identify and operate a particular switch.

  • Patent number: 7375298
    Abstract: An indexing mechanism with positive ON and OFF positions for a motor starter switch mounted in an NEMA 3R enclosure. The indexing mechanism includes a shaft having longitudinally extending projections coupled in fixed relationship to a handle, an index element coupled to the shaft, and a yoke having a pin positioned to engage the index element to positively position the shaft to the first or the second position.

  • Patent number: 7265308
    Abstract: There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch “on” or “off”. The lower edge of the paddle pivots in and out about its upper edge. The switch includes semi-rigid spiral wound driver means having a conical end coupled to be driven by the rocker paddle. When the rocker paddle is pushed in, the paddle urges the semi-rigid driver means to rotate a cam means in a first, clock wise direction, or a second, counter clock wise direction. Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and determines its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by a spring to pivot back to its initial position.

  • Patent number: 7196278
    Abstract: A key operated switch that provides enhanced operational characteristics wherein the rotary motion of a key is translated into the actuation of a switch mechanism that rapidly establishes an electrical connection between a source of electrical current and a load. The switch uses a toggle adapted to interact with a standard switching mechanism which reduces the number of components and the cost of the switch. The key cylinder is coupled to a yieldable member such as spring to provide a positive or snap action when the key cylinder is rotated with a prescribed arc of rotation which reduces the complexity of the switch.

  • Patent number: 7164093
    Abstract: An electrical switch is disclosed having improved operational characteristics wherein when a operating handle is rotated from an OFF position to an ON position the switch provides slow motion which accelerates as the operating handle is rotated to a full open position and then provides rapid establishment of electrical contact. The operating handle having a cam that when rotated from the ON position to the OFF position forces a cam follower downwards. As a result, a bridge having coil springs connected to the cam follower is forced downwards to separate at least one electrical contact placed in proximity to the bridge.

  • Patent number: 7164082
    Abstract: A wiring device common in household circuits includes a flexible brush that is a separate piece from a screw plate that receives electrical power. A terminal screw can thread into the screw plate. The brush may be positioned between the screw plate and the head of the terminal screw and can have a clearance hole through which the threads if the terminal screw can pass. Good electrical and thermal conductivity is assured between the screw plate and the brush by tightening the screw. A ground strap can be employed to hold a cover to a base of the electrical device. The strap can include openings which engage snap tabs on the cover to lock all components into a complete assembly. The strap also can have hooks which engage the cover to prevent the cover from being pulled out of the strap. The wiring device can be an electrical switch, a receptacle, or any similar type of device.

    Abstract: There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch “on” or “off”. The lower edge of the paddle pivots in and out about its upper edge. The switch includes articulated driver means coupled to be driven by the rocker paddle when it is depressed and to urge the rocker paddle back to its out position. When the rocker paddle is pushed in, it urges the articulated driver means to rotate a cam means in a first, clock wise direction, or a second, counter clockwise direction. Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and to determine its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch.

  • Patent number: 6875940
    Abstract: There is disclosed a robust on-off rocker paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch “on” or “off”. The lower edge of the rocker paddle pivots in and out about its top or upper edge. Bias means urges the lower portion of the rocker paddle to always be in its out position whether the switch is in the “on” state or position or the “off” state or position. The rocker paddle of the switch is not located within a frame and the surface of the switch has, along its vertical axis, a contour of positive first differential and zero second differential, comprised of a combination of splines which extend between points of varying distances from a datum plane. The contour has zero second differential when the rate of height increase of individual splines is constant. An actuator coupled to the rocker paddle (the face) of the switch causes a cam to rotate in a clockwise direction and in a counter clockwise direction as the rocker paddle is alternately depressed.

  • Patent number: 5967303
    Abstract: A double pole, single throw switch for high current applications employs two sets of contacts, closed or opened by a toggle lever operating movable contacts on resilient arms into and out of engagement with fixed contacts. The chambers containing the sets of contacts are separated from a spring chamber which contains a flat spring to control the orientation of the toggle lever. Barriers between the spring chamber and each of the contact chambers prevents flashover between the contact sets.

  • Patent number: 5906272
    Abstract: A toggle-type switch employing a cam controlled toggle lever to move or permit to move resilient arms on which are located movable contacts into engagement with fixed contacts. The number of resilient arms and movable contacts and the number of fixed contacts is selected to make and break tie desired number of circuits. The manner in which the circuits are closed or opened depends upon the shape of the cam surface and the cam is spring loaded to hold the toggle in a selected position on a momentary or maintained basis. A slider cooperates with the toggle lever to move selected movable contacts into contact with fixed contacts or allows movable contacts to move out of engagement with other fixed contacts.

  • Patent number: 5826710
    Abstract: A rocker-type electrical switch of the kind known as a "quiet switch" includes a manually depressible rocker having two opposed contact surfaces at a small angle to each other from which rocker depends a rocker arm terminating in a rocker cam. A slider positioned intermediately of the rocker and the rocker cam is moved back and forth by side-to-side movements of the rocker arm and opens and closes one or more pairs of contacts. Rocker movement is controlled by a rocker cam leaf spring engaging the rocker cam which spring has a cammed profile traversed by the rocker cam to slow the switch, lock the rocker and provide other desirable effects. The rocker cam spring is housed in a spring chamber longer than itself, allowing the rocker cam spring to float.
