Abstract
A relay includes a housing, an electric contact system in the housing, an electromagnetic system in the housing, and a magnetic blowing arc-extinguish device. The electric contact system includes a static contact with a static contact portion and a movable contact with a movable contact portion. The electromagnetic system is configured to drive the movable contact to move between a closed position in which the movable contact is in electrical contact with the static contact and an opened position in which the movable contact is separated from the static contact. The magnetic blowing arc-extinguish device includes a permanent magnet statically provided near the static contact and configured to lengthen an electric arc between the static contact portion and the movable contact portion by an electromagnetic force to extinguish the electric arc.
