ABSTRACT:
A vacuum switch which includes two identical facing switch contacts equipped with a cup shaped coil body that is provided with annular contact elements covering the open end of the cup shaped coil body. In order to form turn conductors, the coil body is penetrated by a plurality of throughgoing slots which are inclined relative to the axis and are distributed symmetrically over the circumference of the coil body. A supporting ring is disposed in the cavity between the bottom of the coil body and the contact element which is formed of circular ring sectors. In order to realize high protection against arcbacks, four of the throughgoing slots are provided and are inclined at an angle between 60.degree. and 75.degree. relative to the axis and extend in the circumferential direction between the contact element and the cup bottom at most over a rotation angle between 60.degree. and 90.degree.. Moreover, each circular ring sector is provided with at least one cutin gap which is oriented radially from the inside to the outside, while the supporting ring is disposed in close proximity to the inner diameter of the cup wall.
