ABSTRACT:
An electromagnetic relay having a moving contact plate and fixed contact plates juxtaposed with one another on a base. A moving iron plate is rotated during magnetization/demagnetization of a coil block put on the base to reciprocate a card in a horizontal direction. The moving contact plate is allowed to undergo elastic deformation so that a contact on the moving contact plate is brought into contact and out of contact with contacts on the fixed contact plates. The top corners of the moving contact plate is bent into an upper component and a lower components in such a fashion as to form card acceptance portions, and a distal end portion of the card is brought into contact with an inner surface of the card acceptance portions.
