    Abstract: An electromagnetic relay includes a contactor including a fixed contact and a movable contact, and an electromagnet device for moving the movable contact. The electromagnet device includes a coil generating a first magnetic flux by energization, a tubular body including a permanent magnet generating a second magnetic flux in a direction identical to a direction of the first magnetic flux and having a hollow extending in a center axis direction, a movable element disposed in the hollow of the tubular body and reciprocating in the center axis direction, and a yoke forming a magnetic circuit passing together with the movable element and the tubular body. The magnetic circuit allows at least one of the first and second magnetic fluxes to pass through the magnetic circuit. The electromagnet device is configured to, when the coil is energized, move the movable contact to a first position by attracting the movable element with the first magnetic flux and the second magnetic flux. The electromagnet device is configured to, when energization of the coil is suspended, move the movable contact to a second position different from the first position. This electromagnetic relay is easily designed and reduces power consumption at a low cost.

    Abstract: A contact apparatus is provided and includes fixed terminals having fixed contacts, a movable contact member having the movable contacts provided on one surface thereof so as to come into contact or out of contact with the fixed contacts, a first yoke arranged at one side of said one surface of the movable contact member, and a second yoke arranged at a side of the other surface of the movable contact member, the second yoke having one surface facing the first yoke through the movable contact member. The first yoke is larger in volume than the second yoke.

    Abstract: A circuit interrupter includes a fixed terminal, a movable contactor, a moving mechanism, a squib, and accommodation. The fixed terminal includes a fixed contact. The movable contactor includes a movable contact connected to the fixed contact. The moving mechanism is configured to move the movable contactor from a closed position where the movable contact is connected to the fixed contact to an open position where the movable contact is separated from the fixed contact. The squib is configured to generate gas by combustion. The accommodation is for accommodating the fixed contact and the movable contactor. In the circuit interrupter, the gas is introduced into the accommodation.

    Abstract: A circuit interrupter includes: a first fixed terminal including a first fixed contact; a movable contactor which is formed as a separate part from the first fixed terminal and includes a first movable contact; a holding unit configured to hold the movable contactor so that the first movable contact is connected to the first fixed contact; and a squib configured to generate gas by combustion. In the circuit interrupter, pressure of the gas generated by the squib causes movement of the movable contactor in a direction away from the first fixed terminal so that the first movable contact is separated from the first fixed contact.
