1. An interrupter unit, comprising:
a vacuum switch tube;
an insulating housing at least partially surrounding said vacuum switch tube, said insulating housing having an inner surface provided at least partially with an electrically conductive layer and said insulating housing having a volume material;
an electrically insulating structure material at least partially bordering said vacuum switch tube, said electrically insulating structure material having an outer surface provided at least partially with an electrically conductive layer;
an adhesion layer separating said inner surface of said insulating housing and said outer surface of said vacuum switch tube in an operational state of the interrupter unit; and
a boundary region between said vacuum switch tube and said insulating housing having a layer sequence as follows in a radially outward direction from a switch axis: said structure material of said vacuum switch tube, said outer surface of said structure material, said conductive layer at said outer surface of said structure material, said adhesion layer, said conductive layer at said insulating housing, said inner surface of said insulating housing, and said volume material of said insulating housing.
