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 contactingis interrupted. 本发明涉及一种用于有载分接开关的触点系统，所述触点系统包括可动触点(BK)和固定触点(FK)以及附加触点(ZK)。所述可动触点(BK)在静止状态中直接触点接通所述固定触点(FK)。附加地产生一种状态：所述可动触点(BK)与所述固定触点(FK)通过所述附加触点(ZK)间接触点接通。所述附加触点构造用于在中断所述直接触点接通时可以引导电流在所述固定触点(FK)与所述可动触点(BK)之间流过。
