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.

Claims (10)

1. A relay comprising:

a case; and

a main body comprising:

an electromagnet;

a yoke; and

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 main body is insertable and incorporable into the case by moving the main body relative to the case along a contact/separation direction between the fixed contact and the movable contact,

wherein the fixed contact part is insertable into the case in the contact/separation direction, and

wherein the base has a leg extending in a contact/separation direction, an end surface of the leg is configured to contact the yoke, and the leg is positioned above the armature and is spaced away from an upper part of the armature.
