The invention provides an electromagnetic operation type switching device. The device improves operationality used for crimping spring adjustment, and fastening a nut by high twisting moment for preventing the nut getting loose after a long time is not needed, and the device does not have a problem of plastic deformation of a movable rod. The electromagnetic operation type switching device is characterized by comprising an electromagnetic operation device, a vacuum shutdown switch transmitting driving forces of the electromagnetic operation device through a link mechanism, and a crimping spring maintaining contact of a movable electrode of the vacuum shutdown switch and a fixed electrode in specific contact pressure. An end of the crimping spring is connected with a drive rod used to transmit driving forces of the electromagnetic operation device, and the other end is connected with the insulating rod and is provided with a connecting rod which can be rotatbly supported on the shaft. The connecting rod and the insulating rod are connected, and a junction portion is clamped by a locknut and a nut on the insulating rod, and a junction position of the connecting rod on the insulating rod and the insulating rod is adjusted by a locknut. |
