A method for fitting a carbon brush with a disconnecting device

A method for fitting a carbon brush (10) having a cut-off device comprising a switch-off element (18) such as a bolt element to this pressure acting spring element (20), wherein said disabling outgoing in an extending along the longitudinal axis of the carbon brush of the running surface of the carbon brush opposite end face (14) recess (16) as a blind hole is introduced and the spring element between the switch-off element and the recess on the opening side-sealing plate-like cover member (22, 40, 44) is tensioned, which is integrally connected to the carbon brush, characterized, in that the spring element with the covering outside the is connected to the carbon brush to form a unit and placed in the unstressed state into the recess.
