1. A filter system comprising:
a filter element having an end plate and a filter material for filtering a liquid;
the end plate including a through opening for filtered liquid, a sealing ring surrounding the through opening, and a cover for the filter material;
the sealing ring delimits a free space;
the filter material includes an end that is fixed to the cover, and the filter material surrounds the through opening;
a filter housing in which the filter element is arranged;
a filter head connected to the filter housing; the filter head includes a fluid inlet, a fluid outlet, a switch and/or a bypass valve, and an anti-rotation lock which is connected to the switch and/or to the bypass valve, wherein the filter head and the free space of the end plate form an interface so that the anti-rotation lock can be moved into the free space and/or out of the free space upon actuation of the switch and/or the bypass valve.
