ABSTRACT:
To provide a small-sized electromagnetic relay capable of reducing an internal resistance of a contact circuit as much as possible, and also capable of carrying a high current to the relay. The electromagnetic relay includes an electromagnetic driving block composed by a coil, an iron core, a yoke, and an armature; fixed contacts each provided on one end of each of a pair of terminals fixed to a base; and a movable spring having movable contacts provided at positions corresponding to the respective fixed contacts, the armature driving the movable spring depending on whether or not a current is carried to the coil, thereby opening or closing a contact circuit, wherein the movable spring has both ends supported by the base, the movable spring arranged in parallel to the terminals, and the movable contacts are provided on the movable spring.
