ABSTRACT:
For generating an axial magnetic field, conductor loops are disposed behind the contact members in vacuum switching tubes. The terminals of these conductor loops are supported in axial direction by supporting parts having poor electrical conductivity. In order to reduce the mass of these conductor loops, it is provided that the supporting part be dimensioned such that it represents an electrical shunt to the adjoining conductor loop the electrical conductance of this shunt amounting to at least 1/4 of the electrical conductance of the conductor loop, the invention is suitable for axial field contacts comprising at least one conductor loop disposed behind the contact member.
