1. A current collector for power supply to an electrical load movable along a conductor line, the current collector comprising:
a movable holder for a contact element, whose range of movement is restricted by two mechanical stops and which is acted upon by a spring arrangement exerting a force in the direction of a first end of a range of movement so as to force the contact element against a power rail; and
a damping device which dampens movement of the holder caused by the spring arrangement in the direction of the first end of the range of movement, when the holder is situated within a predetermined first section of the range of movement, which is restricted on one side by the first end and does not include the entire range of movement,
wherein a second section is adjoining the predetermined first section of the range of movement of the holder
wherein a third section is adjoining the second section, the third section extending to a second end of the range of movement that is opposite the first end of the range of movement, and
wherein stiffness of the spring arrangement in the third section is less than in the second section.
