Abstract

Die Erfindung betrifft einen Vakuumschalter (1) mit einer Vakuumschaltröhre (7) mit einem bewegbaren Schaltkontaktelement (29) und einem als ein elektrisch leitfähiger Hohlkörper mit einer zylindrischen Innenwandung (33) ausgebildeten Sockelelement (5), in das ein aus der Vakuumschaltröhre (7) herausgeführter Endabschnitt (31) des bewegbaren Schaltkontaktelements (29) hineinragt. Ein elektrisch leitfähiges Führungskontaktelement (35) ist fest mit dem Endabschnitt (31) des bewegbaren Schaltkontaktelements (29) verbunden. An dem Führungskontaktelement (35) sind voneinander beabstandete Führungsringe (37, 39) und ein elektrisch leitfähiges Stromübertragungselement (41) angeordnet. Die Führungsringe (37, 39) und das Stromübertragungselement (41) verlaufen jeweils ringförmig um das Führungskontaktelement (35) herum und liegen an der Innenwandung (33) des Sockelelements (5) an.
