Abstract

To improve operating reliability and centric guidance of the switch contacts in sealed breaker contact assemblies, a carrier bolt, extending through a flexible membrane into a chamber, and carrying a movable contact, is operated by a lever which has a lever arm movable in the direction of the cam shaft of the breaker assembly, the lever being V-shaped and pivoted at the apex of the V, and engaging the cam shaft with an arm which is opposite to the arm which operates the contact bolt.
