Abstract
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.
