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.

Abstract: The invention relates to a fastening arrangement for fastening a switching device to a mounting tray, the fastening arrangement comprising a fastening point (12) formed in the switching device or the like, and a lug (10) to be fastened to the fastening point (12). The fastening point comprises at least three recesses (16) to receive the protrusion (24) in the lug (10) in such a way that the lug (10) is optionally lockable, when being fastened to the switching device, to different positions defined by the recesses (16), one of the positions being a substantially vertical position, another being a substantially horizontal position, and the rest being positions at an angle between these positions.

Abstract: A fuse holder is disclosed which includes a frame, spring and a limiter,the frame having a first contact member and a second contact member adapted to receive an end of the fuse between them, the spring being adapted to press the contact member against the fuse end, and the limiter being adapted to define the largest possible depth of the fuse end in the installation direction between the first and second contact members. The spring includes a substantially circular arch-formed ring spring adapted to also serve as the limiter.
