In addition, the arc-setting plate is arranged to make the arc generated when the movable contact and the static contact are separated from the arc-striking plate to prevent the arc from burning. The bad parts are burned continuously between the moving contact and the static contact to burn the static and dynamic contacts, reducing the service life.
