Abstract
In a switch device in which the main circuit contact sections of the switch device, an insulating rod, a driving rod, a contact pressure spring, an open spring, and an electromagnet are all coaxially arranged, a problem exists in that the axial dimension of the switch device becomes large. The present invention has been made to solve the aforementioned problem. An object is to obtain an electromagnet device and a switch device using the electromagnet device, in which shortening the axial dimension of the switch device is achieved by arranging the main circuit contact sections of the switch device, the insulating rod, the driving rod, the contact pressure spring, the open spring, and a part of the electromagnet in the same axial range. Particularly, the open spring and the electromagnet are arranged in the same axial region.
