A drive rod for a switch ( 11 ) for high-voltage or medium-voltage installations, having a drive mechanism ( 16 ) for opening or closing the switch. The drive rod ( 10 ) comprises a first, electrically insulating material and in operation is connected to a moving contact ( 14 ) of a vacuum circuit ( 11 ) at one end and to the drive mechanism ( 16 ) at an opposite end. One end of the drive rod ( 10 ) can be coupled to the drive mechanism ( 16 ) by means of a securing body ( 20 ), the securing body ( 20 ) comprising at least one region which is provided with a plurality of projections ( 23 ), which projections ( 23 ), in operation, engage in the end of the drive rod ( 10 ). |
