Abstract: A slide fastener is made from a workpiece formed of a pair of longitudinally extending parallel tapes having confronting edges provided with longitudinally extending and transversely couplable coupling elements. This workpiece is passed along a treatment path through a gapping station, a bottom-stop installing station, a slider-mounting station, a top-stop installing station, and a cutting station. The elements are removed from the tapes at gaps spaced longitudinally of the workpiece in the gapping station and a bottom stop is fitted to the elements at one end of each of the gaps in the bottom-stop installing station. A slider is mounted on the elements at the slider-mounting station between each gap and the following gap and a top stop is fitted to the elements in the top-stop installing station at each gap. Finally the tapes of the workpiece are transversely cut at the gaps at the cutting station into individual slide fasteners.

Abstract: A steering column switch with a rotary pin aligned and parallel to the steering spindle and maintained between socket plates with a switching lever having an annular slider therein encompassing the steering spindle. A rotary pin is retained within a passage in the annular slider. The annular slider is rotatable around the rotary pin and can also be tilted relative to the axis of the rotary pin. The annular slider has a stop profile diametrically opposite the passage for the rotary pin into which a stop spring is engaged. There are contact plates on the rotary pin adjacent the areas where it engages the socket plates. A saddle-shaped contact bridge causes completion of an electrical circuit depending upon the direction of tilting the annular slider.
