  • Patent number: 10600598
    Abstract: The invention relates to a relay, having an electromagnetic drive with a field coil arranged around an iron core which defines a plane, and a yoke. The electromagnetic drive works together with a movable armature which can switch a movable electrical contact via an actuating arrangement. The relay is accommodated in a housing, wherein an intermediate base and/or partition is included between the electromagnetic drive and the contact. The electromagnetic drive is arranged on one side of the partition, and the movable electrical contact is arranged on the other side of the partition. The partition has an opening through which the mechanical actuation of the contact is carried out. Because the armature is pivotable about an axis of rotation perpendicular to the plane of the iron core, the relay can have a lower constructed height than a conventional relay.

  • Publication number: 20140232491
    Abstract: A solenoid-driven automatic bus transfer switch may automatically transfer one or more electrical loads from a first power source to a second power source, or vice versa, in the event of a power failure or other casualty that affects either power source. The transfer switch may be operated in response to the energization of a solenoid coil, which causes a main shaft having a transfer element to rotate from being in contact with the first power source to being in contact with the second power source. The transfer element may be spring-mounted to the shaft, which ensures that a sufficient electrical contact exists between the surfaces of the transfer element and the respective leads of the first and second power sources, regardless of any wear or degradation that may be experienced at any of the surfaces.

  • Patent number: 8395464
    Abstract: Disclosed is a wedge shaped actuator device configured to provide separation of spring supported electrical contacts in an electrical switch. The wedge is configured with dual contour sides to maximize transfer of energy from a drive solenoid to the contact carrying springs. Portions of the wedge are relieved to allow for uninhibited movement of the wedge over side surfaces of the contact carrying springs to avoid digging in of any rough materials from the side edges of the spring as may be occasioned due to stamping techniques used to form the springs.

  • Patent number: 8390410
    Abstract: An electromagnetic relay switches to conduct and interrupt currents having different magnitudes and flowing though mutually opposite paths via the electromagnetic relay. The relay includes a coil generating a magnetic force and a pair of contact sections opened and closed selectively by the magnetic force. The contact sections comprise a pair of fixed contacts and a pair of movable contacts. Each fixed contacts is held by a pair of conductive fixed holders and is near a tip section of each fixed holder. The movable contacts are fixed to a conductive movable holder and moves toward and away from the fixed holders selectively in response to the magnetic force. The relay further includes two arc-extinguishing magnet members adjacent to the contact sections such that, the arc generated by interrupting one current having a magnitude larger than the other current is extended toward the tip section at each contact section.

  • Patent number: 8330564
    Abstract: An electrical switching device including a base terminal that extends substantially in an axial direction and has a base contact. The switching device also includes a movable terminal that extends substantially in the axial direction and has a mating contact. The movable and base terminals extend generally parallel to each other and are separated by a field spacing. The movable terminal is selectively movable to and from the base terminal to electrically connect the base and mating contacts at a contact interface. The switching device also includes a magnetic shield that is located between the movable and base terminals within the field spacing. The movable terminal experiences a separation force when current flows through the base and movable terminals in opposite directions. The magnetic shield is configured to reduce the separation force experienced by the movable terminal to facilitate maintaining the contact interface between the base and mating contacts.
