摘要： A relay includes a pair of fixed terminals arranged to respectively have fixed contacts, a movable contact member arranged to have a pair of movable contacts, a driving structure operated to move the movable contact member and a magnet arranged to extinguish an arc. The movable contact member has a center section located between the pair of movable contacts. The magnet is placed on at least one of a first side and a second side that face each other across a predetermined face including the movable contact member and the pair of fixed terminals electrically connected by the movable contact member. The magnet is arranged to have a magnitude relation that a center area where the center section is located has a lower magnetic flux density than movable contact portions where the pair of movable contacts are located.

摘要： An electromagnetic relay has a movable contact arranged at one end of a drive shaft that reciprocates in an axis center direction based on excitation and demagnetization of an electromagnet block, and a pair of adjacently arranged fixed contacts with which the movable contact is operable to contact and separate. A first electromagnetic iron piece, a second electromagnetic iron piece and the movable contact are inserted to the drive shaft so that the first electromagnetic iron piece and the second electromagnetic iron piece sandwich the movable contact. The second electromagnetic iron piece is biased to one end side of the drive shaft with a coil spring inserted to the drive shaft. When the movable contact contacts to the pair of fixed contacts, the second electromagnetic iron piece forming a magnetic circuit with the first electromagnetic iron piece pushes the movable contact to the pair of fixed contacts.

摘要： The present invention provides an electromagnetic relay that has a long service life, even when being used for interrupting high voltage, and that can be miniaturized. In this electromagnetic relay, the circuit interruption is cut-off by two or more keying circuits, which are operated by a single coil and connected in series. Thus, an amount of generated arc per keying circuit is suppressed. Consequently, the service life of the electromagnetic relay is lengthened. Moreover, the space between the contracts thereof is reduced, so that the electromagnetic relay is miniaturized. Additionally, a magnetic field for extinguishing arc is formed by a back or counter electromotive force generated when the circuit is cut-off. Thus, the generated arc is extinguished.
