Abstract
A vacuum interrupter comprises a vacuum vessel 3, a pair of electrodes 4, 5 disposed within the vacuum vessel 3 so that one is in contact with the other or away therefrom, and a bellows 17 for allowing a movable electrode 5 to be movable with an air-tight relationship. The vacuum interrupter further comprises an auxiliary member 21 disposed between the bellows 17 and the vacuum vessel 3, thereby making it easy to effect the positioning of the bellows 17 and a brazing material. The auxiliary member 21 further serves as a member for absorbing and relaxing an impact appearing at the bellows when the vacuum interrupter is placed in an operational condition.
