Abstract
A contact arrangement for a vacuum switch includes contacts which have central contact surfaces and arc running surfaces surrounding the central contact surfaces. Means are provided to direct current to the area of the central contact surfaces as well as to the area of the arc running surfaces. As the arc foot points approach the edge of the contacts, forces become effective which prevent the arc from leaving the area between the contacts.
