Direct current relay

摘要

The present invention relates to a direct current relay, and more particularly, to a direct current relay capable of reducing an electronic repulsive force generated between a fixed contact and a movable contact by a permanent magnet installed to extinguish an arc. The direct current relay includes: a frame; first and second fixed contacts spaced from each other with a predetermined distance there between; first and second magnetic substances formed to enclose a lower part of the first and second fixed contacts; a movable contact movable to contact or to be separated from the first and second fixed contacts, having a first movable contact contactable to the first fixed contact, and having a second movable contact contactable to the second fixed contact; and a pair of permanent magnets installed on long sides of the frame.
