Abstract

A stationary contact of an electromagnetic contactor having an insulating contact mounting plate, is part of a contact combination that includes a contact arm, a retainer and a fastening screw for electrically and mechanically securing the contact combination to a terminal of the contactor. The contact is mounted on the forward end of the arm and the retainer, constructed of spring sheet material, engages the rear of the arm. The front of the arm and the retainer cooperate to form a recess which receives and grips an L-shaped formation of the mounting plate.
