Power Switch, Especially High Current Switch

Abstract

A power switch, especially a high-current switch, has at least one pole unit with a pole head and a pole base and a vacuum switching tube interposed therebetween. The vacuum switching tube has a stationary contact and a movable contact. The stationary contact is connected to a first conductor rail of the pole unit via a first connecting element. The moving contact is connected to a second conductor rail of the pole unit via a second connecting element. The power switch has a higher current carrying capacity because the first connecting element is welded to the first conductor rail and the stationary contact and the second connecting element is welded to the second conductor rail and the moving contact.
