摘要： A switch can be used for an on-load tap changer. The switch includes: fixed contacts, including a first fixed contact and a second fixed contact; and a moving contact with a first attraction element. The moving contact is movable from a first position into a second position via the first attraction element and a second attraction element, which is arranged outside the switch. The moving contact is configured such that, in the first position, the moving contact contacts neither or only one of the fixed contacts and, in the second position, the moving contact contacts both of the fixed contacts.

摘要： In an electromagnetic relay, length from a movable contact to an end portion of a movable element on a first end side is set greater than length from the movable contact to another end portion of the movable element on a second end side opposite to the first end side. A direction of a Lorentz force acting on a portion of the movable element from the movable contact to the end portion of the movable element on the first end side is conformed to a direction for bringing fixed contacts and movable contacts into contact with each other. Thus, separation between the movable contacts and the fixed contacts due to an electromagnetic repulsive force can be inhibited.

摘要： A switch is disclosed comprising two sets of rod-shaped fixed electrodes formed of a magnetic material and one cylindrical moving electrode formed of a permanent magnet, each set of the fixed electrodes being fixed to the respective end of a cylindrical vessel so that the ends of each set of the fixed electrodes face the ends of the other set of the fixed electrodes with the moving electrode capable of reciprocating between the ends of the two sets of fixed electrodes inside the cylindrical vessel. The moving electrode is comprised of at least one adhesive layer of a metal selected from the group consisting of silver, nickel, copper and alloys thereof on the surface of the permanent magnet, and at least one contact layer of a metal selected from the group consisting of rhodium, wolfram, rhenium, ruthenium and alloys thereof, silver-wolfram, gold-chromium on the adhesive layer of metal. At least the permanent magnet of the moving electrode and the adhesive layer of metal are thermally diffused with each other.

摘要： The electromagnetic contactor has a pair of fixed contacts disposed to maintain a predetermined interval and a movable contact disposed so as to be attachable to and detachable from the pair of fixed contacts, and an electromagnet unit that drives the movable contact. The electromagnet unit has a magnetic yoke enclosing a plunger drive portion, a movable plunger having a leading end protruding through an aperture formed in the magnetic yoke and biased by a return spring, an annular permanent magnet fixedly disposed so as to enclose a peripheral flange portion formed on a protruding end side of the movable plunger and magnetized in a direction in which the movable plunger can move, and an auxiliary yoke disposed on the annular permanent magnet at a side opposite to that of the magnetic yoke and regulating a movement of the peripheral flange portion of the movable plunger.
