A vacuum-insulated switching device contains a grounded vacuum vessel, a contact system having a fixed contact and a moving contact, electrical connecting lines coupled to the fixed contact and the moving contact, and vacuum-tight bushings supported by the grounded vacuum vessel, and provide insulation from the grounded vacuum vessel. The vacuum-tight bushings seal the electrical connected lines. An insulating transmission element is provided. A driving apparatus is coupled to the moving contact via the insulating transmission element and in a vacuum-tight manner. Further vacuum-tight bushings are provided. A further vacuum vessel is disposed in the grounded vacuum vessel. The fixed contact and the moving contact are disposed in the further vacuum vessel and pass out of the further vacuum vessel via the further vacuum-tight bushings.
