Abstract

A high-voltage circuit breaker has a metallic housing. The contact member assembly is held by insulating supports, and has a fixed contact member and a movable contact member. The movable contact member is capable of being driven via an operating lever by means of a drive rod. The drive rod extends through one of the insulating supports. To seal the insulating support from hot quenching gases when the switch is actuated, an insulating disk sealingly surrounds the drive rod and is float-mounted on the insulating support. This allows for compensation of radial movements of the drive rod.
