摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic contactor and an electromagnetic relay, wherein installation of an auxiliary contact unit on the electromagnetic contactor and the electromagnetic relay is easy, and even if there exist abrasion and dimension variations on the contact surface, it is desirable to have a structure hard to come off and easy to detach.;SOLUTION: Two pieces of fixing hooks of an auxiliary contact unit are inserted into a first installation groove of the electromagnetic contactor and the electromagnetic relay, then, one movable hook of the slide plate of the auxiliary contact unit is engaged with and installed on a second installation groove at the end part of the electromagnetic contactor and the electromagnetic relay. The auxiliary contact unit has an elastic body which applies a load on the slide plate so that the movable hook may be engaged with the second installation groove.
