Abstract
A spring carbon brush which can be slid into a holder is blocked in the corresponding feed position on the holder when acted on by forces opposed to the direction of feed by a catch or expansion device in such a way that it can only move in the direction opposed to the direction of feed by overcoming an additional, preferably gradual, elastic force.
