- the first base also acts advantageously as Trä ⁇ ger of the first switching element.
- a further embodiment of the invention provides that the second base comprises a base recess, through which the second switching element is guided from a surrounding ⁇ nen from the second base gas space and extends into the vacuum tube.
- the second socket also advantageously acts as a guide for the second switching element.
- a further embodiment of the invention provides a bellows arranged in the vacuum tube.
- a first folding ⁇ bellows of the bellows is to be ⁇ strengthens the second switching element.
- a second bellows end of the bellows is secured to a bottom of the vacuum tube adjacent the second socket and encloses a bottom recess in the bottom of the vacuum tube corresponding to the socket recess in the second socket.
- the bellows seals the interior of the vacuum circuit ⁇ umrschreibe advantageous against the gas chamber.

- Another embodiment of the invention provides an insulating coat, the vacuum tube and the two base umman ⁇ telt.
- the insulating jacket protects the vacuum switch ⁇ advantageous against environmental influences, especially when using the vacuum switch as outdoor switch.
- a further embodiment of the invention provides that the support elements extend through the insulating jacket. This allows the insulating jacket to rest directly on the vacuum tube, so that no additional insulating gas is required in the area around the vacuum tube.
- a further embodiment of the invention provides that the insulating jacket is at least predominantly made of an electrically iso ⁇ lierenden material.
- resistive components and / or capacitively acting components may be added to the electrically insulating material of the insulating jacket. This makes it possible to influence the electric field generated by the vacuum switch by adding resistively acting components and / or capacitively acting components to the electrically insulating material of the insulating jacket in one area or several areas of the insulating jacket.
- a further embodiment of the invention provides at least ei ⁇ ne control electrode, which is arranged on an outer side of the vacuum ⁇ tube or a base.
