| 摘要 | 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 (145) is attracted to a fixed iron core, based on excitation and degauss of an electromagnet portion, by which the movable shaft (145) reciprocates in a shaft center direction, and a movable contact (148a) of a movable contact piece (148) arranged at another end portion of the movable shaft (145) contacts and departs from a fixed contact. Inside a magnet holder (135) containing the movable contact piece (148), metal position restricting plate (162) that can abut on at least one side of the movable contact piece (148) is arranged. | ||||||
