Zusammenfassung:	The present invention comprises a contact system for an on-load tap changer, which system comprises a movable contact (BK), a fixed contact (FK) and an additional contact (ZK). The movable contact (BK) contacts the fixed contact (FK) directly in a stationary state. In addition, there is indirect contacting between the movable contact (BK) and the fixed contact (FK) by means of the additional contact (ZK). The additional contact (ZK) is designed in such a way that the additional contact can conduct a current between the fixed contact (FK) and the movable contact (BK) when the direct contacting is interrupted.
