Electromagnetic relay

An electromagnetic relay comprising:

• a pair of fixed contacts;
• a moving contactor including a pair of moving contacts corresponding one to one to the pair of fixed contacts and a displaceable portion connected to, and electrically conductive with, the pair of moving contacts and displaceable along with the pair of moving contacts;
• an overlay arranged to overlap with the displaceable portion;
• an electromagnet having an excitation coil;
• and
• an armature configured to actuate the moving contactor by being attracted toward the electromagnet with electromagnetic force generated by the electromagnet to bring each of the pair of moving contacts into, or out of, contact with a corresponding one of the pair of fixed contacts,
• the armature having an adhering portion to be adhered onto the electromagnet with the electromagnetic force generated by the electromagnet,
• the overlay having an opening that exposes a part of the displaceable portion,
• a space inside the opening crossing a predetermined plane that intersects at right angles with an arrangement direction in which the pair of moving contacts is arranged side by side,
• the predetermined plane passing through a center between both ends in the arrangement direction of the adhering portion.
