電磁継電器。 By energizing an electromagnetic block having a substantially U-shaped iron core with a permanent magnet arranged in the center, the movable iron piece rotates in a seesaw shape around the part adjacent to the permanent magnet, and at the same time, the movable iron piece is integrated with the movable iron piece. In an electromagnetic relay in which a movable contact piece is driven to open and close a contact, a hinge spring extending laterally from the center of rotation of the movable contact piece is protruded from the upper surface of the base and folded outward. An electromagnetic relay characterized in that it is bent and fixed to a welded receiving part of a common terminal that is adjustable from the side.
