An electromagnetic relay includes a fixed contact module including a fixed contact, a movable contact module including a movable contact disposed to face the fixed contact, an armature formed of a magnetic material and configured to move the movable contact module to bring the movable contact into and out of contact with the fixed contact, and an electromagnet configured to generate a magnetic field to move the armature. At least one of the fixed contact module and the movable contact module includes a joint at which different components are joined by riveting, and a film with a thermal conductivity higher than, the thermal conductivity of the fixed contact module and the movable contact module is formed on at least one of the fixed contact module and the movable contact module including the joint.

Electromagnetic relay

An electromagnetic relay includes an electromagnet, an armature configured to shift in response to a magnetic force generated by the electromagnet, a movable spring having a movable contact disposed thereon, a fixed spring including a first contact strip and a second contact strip, the first contact strip having a first fixed contact disposed thereon, the second contact strip having a second fixed contact disposed thereon, the first fixed contact and the second fixed contact facing the movable contact, and a linkage member configured to link the armature and the movable spring to shift the movable spring in conjunction with movement of the armature.
