Abstract
The invention relates to a stepping switch comprising vacuum switching tubes. The general inventive concept consists in providing one or more cam disks which have profiled circumferential contours both on the upper or lower face as well as on the lateral face, said contours being in the shape of cams for example, so that the vacuum switching tubes can be actuated by both the profiled circumferential contour of the lateral face as well as by the contour of the upper or lower face.
