A base of a relay has a leg extending in a contact/separation direction between contacts, and the leg is configured to come into contact with a yoke when the base is incorporated into a case. The leg is spaced away from an upper part of an armature by a distance. This distance is determined so that an upper surface of the armature does not come into contact with the leg in a normal operation of the armature, but the upper surface of the armature comes into contact with a lower surface of the leg when the armature jumps up beyond a movable range thereof due to, for example, a strong impact applied to a vehicle on which the relay is mounted.

A high voltage relay resistant to instantaneous high-current impact is disclosed, and includes an electromagnet system, a control system, a contact system, and a base support. In the present solution, an electromagnetic force generated by the contact system is used to resolve a problem of contact separation caused by an electric repulsion force generated by an instantaneous high-current.
