"FRICTION BRUSH WITH MEANS FOR AUTOMATIC DISCONNECTION WHEN CONSUMING THE CARBON WEAR" characterized by the fact that a bushing is embedded on the head of the brush, inside which a spiral spring is placed, which exerts pressure on a core or plug of suitable insulating material, housed in a cavity, which penetrates inside the body of the brush, to a depth that corresponds to the maximum height at which the wear of the carbon can reach, so that when the core is expelled outside the brush, its automatic disconnection occurs.
