Abstract
An axially reciprocatable actuation rod is conducted out of a vacuum chamber and connected with one of the terminals of a vacuum switch by a connecting conductor. In order to exploit the short switching stroke which is characteristic of vacuum switches and thereby reduce the construction expenditure for the connecting conductor, the connecting conductor is constructed as a yoke whose ends are forked. These opposed ends of the connecting conductor engage at one end thereof the actuation rod and at the other end thereof a protrusion on the terminal extending in the direction of the actuation rod. The opposed ends frictionally engage the actuation rod and the protrusion elastically at mutually opposing locations thereof.
