Abstract

A multi-pole vacuum switch which has, for each vacuum switching tube, a pole operating unit with a lever arrangement for changing the direction of movement produced by a drive device. Two toggle levers are arranged in a casing of the pole operating unit. A first toggle lever is connected to the operating plunger of the vacuum switching tube and the second toggle lever is connected to a supporting lever. The supporting lever acts on a contact pressure spring via a pull rod. In the switched-on position (where the switch is closed), the first and second toggle levers are close to dead center. An adjustment device permits the toggle levers to be adjusted relative to the supporting lever.
