Abstract

A clutch for a motor vehicle has a sensor device (7) for detecting the limit of wear of friction linings (6), with an electric switch (11) having an electric conductor (13). The electric conductor (13) is severed by a rotatably mounted switching part (14) when the limit of wear is reached. Before the limit of wear has been reached, the switching part (14) is biased by a blocking part (15) into a position remote from the electric conductor (13). It is possible thereby to determine the limit of wear with particular exactitude.
