摘要

The switch is mounted on a tube end (1) and consists of a fixed casing (2) connected with the tube end, as well as of one casing (3) with at least one lever (20, 21), connected axial with the fixed casing, which can be turned by hand, whereby the fixed and the rotatable casing form an unit. The fixed casing comprises a part (4) which comprises a rope guide (9) in a slot (15) for the guidance of a traction rope (8), and a support, alternatively with an end part (6), for supporting a sheath (7) around the traction rope (8). An aperture (13) is provided for inserting the rope, which is arranged as a channel with two outputs in the unit of fixed and rotatable casing. The aperture comprises a size which allows a traction rope (8) with a nipple (10) to be inserted, and the nipple to be fastened to the rotatable casing without disassembling the unit or parts of it.
