Abstract

The stationary pole contact has a stationary contact part, which is fastened to a shaft in an insulating wall. The contact also has a guide bolt (6) which extends radially inwards. This has a stop to which a contact plate can be moved against the force of a spring in the direction of the insulating wall. A corresponding movable pole contact stretches across the contact plate laterally. Several compression springs are arranged with different geometric arrangements relative to each other, around the spring bolt (6) to generate the spring force. The spring force, on the side of the fixed contact from which the movable contact approaches to make contact, is less than that on the other side.
