Abstract
The invention relates to an arrangement for attaching a switch control shaft to a switch pipe shaft, where the control shaft is mounted partly in the switch pipe shaft and tightened to the switch pipe shaft by a screw. The arrangement comprises a tightening piece. The screw is arranged to act on the control shaft through the tightening piece so that when the screw is turned, the tightening piece is arranged to press the control shaft against the pipe shaft so that the control shaft tightens fast between the tightening piece and the pipe shaft.
