Abstract
1318034 Rotary switches; indicators for switches SOLARTRON ELECTRONIC GROUP Ltd 16 Oct 1970 [20 Oct 1969] 51408/69 Heading H1N Electrical switching apparatus wherein coaxial knobs 16, 18 independently rotate concentric shafts 12, 14, respectively, and each knob has a datum index 36, 40, for co-operation with markings 20 on a mounting panel 15, has auxiliary indexes 38 extending substantially from front to rear of the rear knob 16 whereby the position of the front knob 18 can be read by following the aligned auxiliary index from the datum ndex 40 to the markings 20 on the panel. As shown, the knobs control respective wipers 22, 28 moving over contacts 26, 32 and both knobs preferably move stepwise under action of detent mechanism, not shown; but they may move continuously to operate potentiometers, for example. The front datum index may co-operate alternatively (Fig. 3, not shown) or additionally (Fig. 4, not shown) with the grooves between ribs on the rear knob, and the rear knob may have straight lines as auxiliary indexes.
