ABSTRACT:
An adjusting knob assembly includes a knob member having a knob and an axially extending shaft. A support bracket has an aperture defined in part by a gapped ring section formed by a pair confronting arcuate fingers. The shaft and the aperture have complimentary, longitudinally extending, circumferentially distributed flat surfaces, which provide discrete angular positions for the shaft when the complimentary flat surfaces are in register. Preferably, the gap between the confronting fingers is sized, and the arcuate fingers have a compliance sufficient that the shaft may be passed laterally through the gap and snapped into the aperture. Any one of a plurality of interchangeable cam members can be press fit on to the end of the shaft.
