Abstract

A double-contact switch has first and second tubular vacuum switching chambers; a stationary electrode, between the first and second vacuum switching chamber, having a first stationary contact protruding into the first chamber and a second stationary contact protruding into the second chamber; a first electrode, arranged in the first chamber, moveable axially therein, having a contact support region and sealed off from the first chamber exterior; a second electrode, arranged in the second chamber, moveable axially therein, having a contact support region and scaled off from the second chamber exterior; a first contact compression spring applying a first spring force to the first movable electrode so the first electrode contact presses onto the contact protruding into the first chamber; and a second contact compression spring applying a greater, second spring force to the second movable electrode so the second electrode contact presses onto the contact protruding into the second chamber.
