Abstract
(EN)
A multi-contact point direct current relay according to an embodiment of the present invention comprises: an enclosure; a yoke installed in the enclosure and forming a magnetic path; a plurality of bobbins installed above the yoke to be spaced apart from each other; a plurality of coils wound on the plurality of bobbins, respectively; a plurality of fixed contacts installed above the plurality of coils, respectively, to be spaced apart from each other; and a movable contact which is disposed between the plurality of fixed contacts and is operated to come into contact with or be separable from a fixed contact of the plurality of fixed contacts, wherein in a neutral state, the movable contact does not come into contact even with any fixed contact among the plurality of fixed contacts, and when a magnetic force is generated in one coil among the plurality of coils, the movable contact comes into contact with a fixed contact disposed above the one coil.
