  • Patent number: 9443681
    Abstract: An electrical switch includes a tubular housing having a conductor receiving end and an operating end opposite the conductor receiving end. The tubular housing also includes a conductive interface positioned intermediate the conductor receiving end and the operating end. An operating rod extends through the operating end toward the conductor receiving end. The operating rod is moveable between a first position to engage the electrical switch and a second position to disengage the electrical switch. A gelatinous dielectric material is provided within a portion of the tubular housing, and around the operating rod, in the operating end to prevent voltage from the conductive interface from arcing to the operating end. The gelatinous dielectric material is configured to deform to maintain contact with the operating rod in the first position and the second position.

  • Patent number: 9336972
    Abstract: A switch device includes a lever and a pusher. The pusher includes a surface that contacts the lever. When force is applied from the lever to the pusher, an inclined surface of the pusher produces a force that moves the pusher from a one-side pushing position to a two-side pushing position. This allows for a user to apply a smaller force to the lever in order to move the pusher from the one-side pushing position to the two-side pushing position and thereby push two switch units.

  • Patent number: 9318284
    Abstract: A circuit interrupter having a compact design. According to some implementations, the circuit interrupter includes a conductor from a terminal to a contact having a portion that is angled with respect to the housing sides. This allows a fastener sleeve used to secure the device housing to be positioned closer to the center of mass of the housing, reducing the area of the housing. In some implementations, an arc splitter is provided which includes conductive plates that are angled with respect to the housing sides, allowing the area of the housing to be reduced. In some implementations, a terminal is designed to accommodate a connection without being doubled back, reducing the clearance required for the terminal and the overall area of the circuit interrupter.

  • Patent number: 9312082
    Abstract: An interlock structure is coupled between actuating structure and a travel adjuster of a circuit breaker. The interlock structure includes a body having a bore therein. An engaging member has a portion sized to be received by the bore and the engaging member is coupled with the travel adjuster for movement therewith. A slide member is movable with respect to the body between operative and inoperative positions. Linkage structure is coupled to the slide member for moving the slide member and is also coupled to the actuating structure such that upon movement of the actuating structure, the linkage structure moves the slide member to the operative position so that the slide member blocks at least a portion of the bore to prevent the engaging member from entering the bore and thus prevents the travel adjuster from moving in a certain direction to allow the closure of the circuit breaker contacts.
