Claim:
1. An electromagnetic contactor that is adapted to couple to a driving electromagnet when the driving electromagnet is an alternating current (AC) electromagnet including a movable core and an AC electromagnet coupling spring inserted into a through hole arranged on a mounting face of the movable core, and is also adapted to couple to the driving electromagnet when the driving electromagnet is a direct current (DC) electromagnet including an armature and a DC electromagnet coupling spring arranged at a contact face of the armature, the electromagnetic contactor comprising: a contact support configured to hold a plurality of movable contacts in alignment to be coupled with the driving electromagnet and driven by the driving electromagnet, wherein the contact support comprises a coupling portion including, at a part of the electromagnetic contactor to couple to a coupling face of the electromagnet: a movable core contact portion extending in a direction crossing an alignment direction of the plurality of movable contacts, and adapted to contact the mounting face of the movable core of the AC electromagnet when the driving electromagnet is the AC electromagnet and is coupled to the electromagnetic contactor; coupling spring edge accommodation portions arranged on both sides of the movable core contact portion, at least the movable core contact portion and one of end parts in an extension direction of the movable core contact portion being opened; and armature contact portions arranged on opposite sides with respect to the movable core contact portion of the coupling spring edge accommodation portion, and adapted to contact the contact face of the armature of the DC electromagnet, when the driving electromagnet is the DC electromagnet and is coupled to the electromagnetic contactor.
