 formed or in some way, advantageously by electroplating, are applied.



   FIGS. 1 and 2 of the drawing illustrate such a shift change in front view and cross section.



   The switching change consisting of a conductive panel a has the bumps b and depressions c necessary for the desired switching, which are produced in the manner indicated above.



   This switching change, in the present case in the form of a flat panel, is moved past fixed contact points in one plane in order to effect the various switching operations.
