Abstract
An object of the present invention is to provide a contact switching device that does not cause a contact failure due to resin powder, and has higher contact reliability. For this, there is a contact switching device in which a movable iron core provided at one end portion of a movable shaft () is attracted to a fixed iron core, based on excitation and degauss of an electromagnet portion, by which the movable shaft () reciprocates in a shaft center direction, and a movable contact () of a movable contact piece () arranged at another end portion of the movable shaft () contacts and departs from a fixed contact. Inside a magnet holder () containing the movable contact piece (), metal position restricting plate () that can abut on at least one side of the movable contact piece () is arranged.
