Abstract
Contact arrangement for vacuum switch in which one of two contacts is movable relative to the other in the axial direction of the contacts and is designed as a recessed contact. According to the invention, a condensation plate with a diameter greater than the inside diameter at the rim of the recessed contact is provided between the other contact and its current lead. The sidewall of the recessed contact forms a guide ring for the metal vapor, a substantial part of which condenses on the condensation plate.
