Abstract
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.
Claims1
A relay comprising:
- an electromagnet;
- a yoke;
- a movable contact part having an armature configured to operate corresponding to an activation of the electromagnet, a movable spring attached to the armature, and a movable contact attached to the movable spring;
- and
- a fixed contact part having a base to which a fixed contact opposed to the movable contact is attached,
- wherein the base has a leg extending in a contact/separation direction between the fixed contact and the movable contact, the leg contacts the yoke, and the leg is spaced away from an upper part of the armature.
