Abstract
A vacuum switching tube has a cylindrical housing, including an insulator which directly surrounds contact pieces of the tube. The radial distance of the insulator from the contact pieces is less than or at most equal to the length of the contact stroke. In addition, the contact pieces can be structured as axial magnetic field contacts, and the free cross-section can be narrowed in the back space of the contact pieces by radial expansion at the contact pins or by radial constriction of the insulator.
