Zusammenfassung:	A tap changer for uninterrupted switching between winding taps of a tapped transformer has first and second load branches for each phase to be switched. Each load branch has a main vacuum switch and in parallel thereto a series connection of a switch-over resistance and a respective auxiliary vacuum switch. First and second vacuum switching tubes each contain the main vacuum switch of the respective first and second load branches and the auxiliary vacuum switch of the other of the load branches.
