In a seesaw type electromagnetic relay comprising an armature carrying out a seesaw motion by excitation of an electromagnet, and a movable spring which carries out the seesaw motion in synchronism with the seesaw motion of the armature and which comprises a par of spring sections, at least one of the spring sections forks into two branches to form a pair of spring pieces one of which is bent downward. A pair of movable contacts is mounted at both free end parts of the movable spring on a bottom surface of the movable spring. One of the movable contacts is mounted at the free end part in the spring pieces on bottom surfaces thereof to form a pair of movable contact elements acting as a twin movable contact. A pair of fixed contacts faces the pair of movable contacts. In an open state, a distance between one of the movable contact elements in the twin movable contact and the fixed contact opposed to the twin movable contact is different from another distance between another of the movable contact elements in the twin movable contact and the fixed contact opposed to the twin movable contact. The fixed contact opposed to the twin movable contact may consist of a twin fixed contact having a difference in level.
