Abstract

519,536. Multi-position rotary switches. TURNER, C. A., and DIAMOND H. SWITCHES, Ltd. Sept. 19, 1938, No. 27304. [Class 38 (v)] Rotation of a knob 9 and spindle 8 to a selected position brings one or more slots 18 in a plate 17 opposite selected plungers 15' which thereupon move upwards and allow selected spring blade contacts 10 to engage co-operating contacts 13. The contacts 10 form part of a spider, Fig. 6, connected to a central terminal 21 so that rotation of the knob brings the terminal into electrical connection with selected circuits. The individual switching positions are determined by spring balls 5 engaging depressions between teeth in a cam 4, and the plate 17 may form part of a block having cam surfaces which press two blade contacts 22, 23 out of engagement with fixed contacts 24, 25 in the main circuit. The fixed contacts 13 may be connected to tappings on a resistance or transformer. The switch may be fixed to a panel by hooklike ends of a plate 30.
