Abstract
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.

1-11. (canceled)
A vacuum switching device for a medium or high voltage, comprising:
- a drive rod;
- two contacts, at least one of said two contacts is mounted so as to be mechanically movable via said drive rod and at a same time is electrically connected to said drive rod;
- a vacuum space in which said contacts are disposed;
- and
- a spring contact disposed outside said vacuum space, said drive rod, in a closed state of said contacts, is electrically connected to a power line via said spring contact, and in that said spring contact, in an open state of said contacts, is electrically insulated from said drive rod.
