Abstract A high-voltage switching device is described having at least two series-connected vacuum switching chambers. The vacuum switching chambers, which are disposed in series, are configured differently with regard to their physical size and/or contact configuration, such as the contact diameters, a separation between the contacts, and contact types. At least one vacuum switching chamber of a first type is provided, and at least one vacuum switching chamber of a second type is provided. The vacuum switching chambers are selected in such a manner that re-ignitions and restrikes of a vacuum switching chamber of the first type are coped with by at least one other vacuum switching chamber of the second type. The opening of the contacts of the two vacuum switching chambers at different times is used as an additional method for operation of the high-voltage switching device.
