Abstract: 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).
