Abstract:
In order to provide a contact switching device with a high degree of contact reliability and which is not susceptible to contact defects caused by resin powder, a movable iron core provided to one end of a movable shaft (145) is attracted to a fixed iron core, in accordance with the excitation and demagnetization of the magnet, thereby moving the movable shaft (145) in a reciprocating manner in the axial direction, and making the movable contact (148a) of the movable contactor (148) disposed on the other end of the movable shaft (145) approach and move away from the fixed contact. Then, a metal position restricting plate (162), which can come into contact with at least one side of the movable contactor (148), is disposed inside the magnet holder (135) that houses the movable contactor (148).
