摘要： A bellows of which one end portion is fixed to a movable lever 35 passing through a vessel wall and swinging and the other end portion is fixed to the vessel wall 3 is characterized in that the spring constant of the above-mentioned bellows at a central portion in an expansion direction is made smaller than that at the end portions in the expansion direction. The bellows can damp stress concentration at end portions and improve the life, without enlarging the size of the bellows. And a vacuum switch has the bellows used therein.

摘要： There is disclosed a vacuum insulation switch provided with a movable electrode, a stationary electrode and an earthing electrode, which are insulated from each other, in a vacuum container made of a conductive material which is earthed, and a switchgear using the same. Since the vacuum insulation, which is excellent in the insulation ability, is utilized, the switch is drastically miniaturized and the number of constituent parts are reduced, whereby the manufacturing cost of the switch and the switchgear can be decreased.
