    摘要： The present invention relates to an enclosed type electromagnetic switch having a status indication function, and more particularly, to and enclosed-type electromagnetic switch having a status indication function that can show the electromagnetic switch's status on an enclosure. An enclosed type electromagnetic switch having a status indication function according to an exemplary embodiment of the present invention comprises: an enclosure (10); an electromagnetic contactor installed inside the enclosure; an auxiliary contact unit attached to one side of the electromagnetic contactor; an overload relay installed inside the enclosure and providing a trip signal to the electromagnetic contactor. The enclosure comprises: a first indicating means (40) that shows that the electromagnetic contactor is in the on state; and a second indicating means (45) that shows that the electromagnetic contactor is in the off state, wherein the first indicating means (40) is connected to contacts a (NO contacts) of the auxiliary contact unit, and the second indicating means (45) is connected to contacts b (NC contacts) of the auxiliary contact unit.
