A switching system for an on-load tap changer includes a rotatable ring stack, wherein the rotatable ring stack is part of an internal Geneva mechanism and a drive system. The ring stack includes a first current carrier ring and a second current carrier ring each of which is selectively electrically coupleable to one of a plurality of contact elements of the tap changer, and a Geneva ring. The drive system includes a driving wheel, wherein the Geneva ring is mechanically coupleable with the driving wheel, such that the Geneva ring is rotatable by the driving wheel, and the first and the second current carrier rings each are coupled with the Geneva ring such that a rotation of Geneva ring causes a joint rotation of the first and the second current carrier ring.
