Abstract
A switching device that causes a force to act on an arc to diffuse the arc, has a magnet that generates a magnetic field in a direction orthogonal to a direction of the arc, the arc being generated at moment at which a movable member is brought into contact with or separated from a contact of a fixed member to switch between electric conduction and electric cutoff. The magnet is a plastic magnet in which metal is exposed to a surface of the magnet.
