Abstract
An electromagnetic contactor having normally open and normally closed contact pairs 22, 26 includes a movable crossbar 12 having apertures 14 with sloping guide surface 18', 18' for guiding movable contact members 16 disposed in the apertures. These sloping surfaces serve to jam the crossbar against the base 10 of the contactor when the crossbar is moved in a direction to open fused contact pairs, to thereby prevent the normally open and normally closed contact pairs from being closed at the same time.
