FIELD: electricity.
SUBSTANCE: invention relates to a carbon brush (10) with a disconnecting device (20) disposed in a cavity (12) of a brush body (11) and comprising a disconnecting element (21) made of an electrically insulating material and a pre-compressed resiliently loading pressure spring member (24). The pressure elastic member (24) is formed by at least one spring (25) with several coils (25, 27, 28), which in the pre-compressed state of the spring are at least partially located inside each other, the smallest coil (26) is located inside its next greater coil.
EFFECT: reduced costs for spare carbon brushes.
