Abstract
An electromagnetic contactor in which an arc extinguishing chamber is defined by an insulating base and a box attached removably to the insulating base. In the arc extinguish chamber, there are accommodated fixed contact elements having fixed contacts, a movable contact element having a movable contact adapted to be brought into and out of contact with the fixed contacts of the fixed contact elements, a commutation electrode for receiving arcs established when the movable contact comes out of contact with the fixed contacts, arc extinguish metal plates for extinguishing arcs commutated to the commutation electrode, and an extinguishing plate support for supporting the arc extinguishing plates. The extinguishing plate support is formed with a groove or hole for receiving the end portion of the commutation plate so that it is held on the commutation electrode. By elastically clamping the commutation electrode between the inner wall faces of the box defining the arc extinguishing chamber, the extinguishing plate support is held in the arc extinguishing chamber by the commutation electrode.
