ABSTRACT:
A vacuum switching tube includes a pair of switch contacts having a larger diameter than their appertaining contact pins, an axial magnetic field being generated in the region of the switch contacts by a shield having high electrical conductivity. The shield is subdivided in an axial direction, is not connected electrically to any of the switch contacts, and is arranged potential-free. The present vacuum switching tube is suited for vacuum switching in a high short circuit breaking capacity.
