A carbon brush with a disconnection apparatus in a cavity in a brush body includes a disconnection body and a prestressed compression-spring body. The disconnection body consists of an electrically insulating material, and the prestressed compression-spring body is configured to act resiliently on the disconnection body. The compression-spring body is formed together with the disconnection body as a short component with a short axial length. In one embodiment, the compression-spring body is in the form of a spring with a plurality of spring turns which, at least in the prestressed, compressed state, are at least partially located one inside the other, shortening them. |
