A selector (1) for an on-load tap changer, comprising a tap selector (2) with at least one selector arm (21, 22); a change-over selector (4), characterized in that the change-over selector (4) is actuated via at least one of the selector arms (21, 22) of the tap selector (2).

An on-load tap changer has a contact system. The contact system includes: a fixed contact; a movable contact; and an auxiliary contact. The moveable contact is configured to directly contact, in a stationary state, the fixed contact. The auxiliary contact is configured to electrically connect, in addition to the direct contact, the movable contact with the fixed contact in the stationary state. The auxiliary contact is constructed and arranged to conduct a current between the fixed contact and the movable contact in the event of interruption of the direct contacting.

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.
