Abstract: The present embodiments relate to a device for establishing an electrical contact between two device elements moving relative to each other. The device includes a plurality of brushes that may be arranged on one of the device elements and establishes contact on the relative movement of the device elements along a slideway provided on the other device element. The brushes are arranged staggered one behind the other relative to a direction of movement determined by the relative movement. The brush arrangement according to the present embodiments is more robust than conventional arrangements with respect to wear and ageing.
