Abstract: A diverter switch is for an on-load tap-changer. The diverter switch includes: at least one vacuum interrupter; an actuating element, which is mechanically connected at a first end of the vacuum interrupter and has a roller at a second end; and an actuating body having a base body and having at least one cam. The vacuum interrupter is configured to be actuated via the actuating element as a result of the roller moving over the actuating body. At least one part of the cam has a higher strength than the base body.

Abstract: The invention relates to a load transfer switch for a tap changer for switching among various winding taps of a step transformer without interruption. The general inventive concept lies in fastening both the force accumulator and the load transfer switch not on the bearing plate but rather on the force accumulator support by providing additional receptacles on the force accumulator support, which receptacles are supported over a large area on the oil tank, in particular on the upper permanent main contact supports fastened to the oil tank, of each phase of the load transfer switch in such a way that the force accumulator support is fixed both in the horizontal direction and the vertical direction and thus mechanically unburdens the bearing plate.
