| Zusammenfassung: | A vacuum switching device for medium or high voltages contains two contacts. At least one contact of which is mechanically movably mounted by a drive rod and thus is in electrical contact with the drive rod. The vacuum switching device has a vacuum chamber in which the contacts are arranged. The vacuum switching device has a spring contact, which is outside the vacuum chamber, and the drive rod, when the contacts are closed, is in electrical contact with a power line via the spring contact, and in that the spring contact, when the contacts are open, is electrically insulated from the drive rod. |
