Abstract
There is provided a contact switching device which has high productivity and in which operation characteristics hardly vary. The contact switching device includes an electromagnetic unit, a holder, a movable shaft, a movable yoke, a movable contact piece having movable contacts at both ends, fixed contacts, and a fixed yoke. At the time of excitation of the electromagnetic unit, the movable shaft moves to the holder side along a direction of an axis center. A magnetic circuit is formed of the fixed yoke and the movable yoke due to a magnetic field generated by a current that flows into the movable contact piece as a result of the movable contacts coming into contact with the fixed contacts. The movable yoke is then attracted to the fixed yoke.
