Title: Contactor having interlock for movable contact carrier

Abstract: An electromagnetic contactor having a removable cover in front of its contact area is provided with a molded plastic interlock member biased by a torsion spring toward a blocking position in the path of the movable contact carrier. In this position of the interlock member the latter prevents closing of the contactor. However, when the cover is secured in its closed position, engaged complementary inclined cam formations on the cover and interlock member hold the latter in a position remote from the movable contact carrier thereby permitting the contactor to be closed.
