Vacuum switch chamber drive has movable contact rod acted on by cam surface with 2 sliding or rolling cam sections for movement into switch closed and open positions

摘要

The drive is coupled to a movable contact rod (13) for the vacuum switch chamber (10), with a cam surface (32a,32b,32c), cooperating with a linearly displaced cam carrier (31), having 2 sliding or rolling cam sections (32a,32b) respectively moving the contact rod into the on and off switch position.
