Abstract:
An electromagnetic relay includes a fixed iron core; a movable iron core disposed opposing to the fixed iron core; a coil for generating a magnetic force when energized to make the movable iron core attracted by the fixed iron core; a movable contact coupled with the movable iron core; a fixed contact disposed opposing to the movable contact; and a reset spring for resetting the movable iron core when the coil is de-energized. The movable iron core includes a base body to which an expanding force of the reset spring is applied and a movable member provided independently from the base body. The movable member is attracted by the fixed iron core when the coil is energized to move integrally with the base body, and is reset by the expanding force of the reset spring when the coil is de-energized to slide independently from the base body.
