  • Patent number: 9548174
    Abstract: A switch assembly adapted and a method for switching power to a circuit having a power source. The switch assembly includes current carrying contacts and a coupling member. The coupling member has conductive pads for engaging the current carrying contacts and a contact bridge extending between the conductive pads. An actuator assembly moves the coupling member between a closed position in which the conductive pads of the coupling member engage the current carrying contacts and an open position in which the conductive pads of the coupling member are disengaged from the current carrying contacts. Opposing electromagnetic forces are generated between the contact bridge and the conductive pads to resist electromagnetic repulsion forces generated between the current carrying contacts and the conductive pads as the actuator assembly approaches or is in the closed position.

  • Patent number: 9373468
    Abstract: A contactor or switch assembly adapted for switching power to a circuit. The housing has internal walls that laterally extend within the interior compartment to define a protection chamber. Current carrying contacts are disposed in the protection chamber of the housing. The current carrying contacts include conductive bodies that protrude from the housing and are configured to close the circuit. Arc dissipation areas are provided in the protection chamber and are located proximate to the current carrying contacts. Magnets are provided proximate ends of the dissipation areas. The magnets create magnetic flux or a magnetic field that extends across the current carrying contacts. The magnetic flux directs electric arcs radiating from one or more of the current carrying contacts into the arc dissipation areas, thereby increasing the effective distance that the electric arcs travel wherein the electric arcs are dissipated in the dissipation areas.

  • Patent number: 8232499
    Abstract: A contactor assembly is adapted for switching power to a circuit having a power source. The contactor assembly includes a housing, carry contacts, and arc contacts. The housing defines an interior compartment and includes internal chamber walls that laterally extend within the compartment to define a protection chamber. The carry contacts are disposed in the protection chamber of the housing. The carry contacts include conductive bodies that protrude from the housing and are configured to close the circuit. The arc contacts are disposed in the housing outside of the protection chamber. The arc contacts include conductive bodies that protrude from the housing and are configured to close the circuit. The internal chamber walls of the housing prevent material that is expelled from one or more of the arc contacts when an electric arc emanates from one or more of the arc contacts from contaminating one or more of the carry contacts.

  • Patent number: 8148655
    Abstract: A pressure sensor is provided for a container having a hermetically sealed internal chamber. The pressure sensor includes a support member having a membrane side and an electrical contact extending along the membrane side. The support member is configured to be held by the container such that at least a portion of the support side is exposed to the internal chamber of the container. The pressure sensor also includes a membrane having a chamber side and an opposite support side. The membrane is held by the support member such that the chamber side is configured to be exposed to the internal chamber and the support side is configured to be isolated from the internal chamber. A pressure differential across the chamber side and the support side of the membrane deflects the membrane into and out of engagement with the electrical contact of the support member.

  • Patent number: 6476697
    Abstract: A modular, multi-phase electrical relay contactor assembled from a number of electrical relay contactor units. Each unit has a housing, an electromagnetic motor located within the housing, a pair of stationary contacts attached to the housing, a moveable contact, and a moveable contact carrier. The moveable contact carrier is engaged with the moveable contact and has a metallic clapper plunger attached to its upper end. A protrusion extends from one side of the moveable contact carrier and an aperture, sized to receive the protrusion of another electrical relay contactor unit, is formed through another side of the moveable contact carrier. A plurality of units are adapted to be connected together such that when engaged, the protrusion extending from the moveable contact carrier of a forwardly located unit will fit into the aperture formed in the moveable contact carrier of a rearwardly located unit, thereby providing synchronous movement of the plurality of moveable contact carriers and the moveable contacts.
