Abstract
A device for operating switches includes a plurality of interlinked hydraulic switching devices (7) offset in the longitudinal direction of the rails. The first mechanical switching device is connected with a hydraulic cylinder/piston unit acting as a pumping element, the working volumes (13) of this first hydraulic cylinder/piston unit (7) acting as a pumping element being connected with the working volumes (13) of consecutive hydraulic cylinder/piston units (7) so as to be driven in same direction.
