Abstract

1,204,429. Catch fastenings. SQUARE D CO. 20 Nov., 1968 [12 Feb., 1968], No. 54964/ 68. Heading E2A. [Also in Division H1] A detent locating device for a push-pull operated electric switch comprises cam projections 66 Fig. 3 mounted on the push-button stem 38 and engaged between pairs of resiliently urged cams 84 axially located in the switch housing 40 (not shown) and movable in a circumferential path about the stem 38. Compression coil springs 96 for the cams 84 are circumferentially arranged around the stem 38 between the pairs of cams. In the example of Fig. 3 the cams 84 are shaped to urge the stem, 38 to an intermediate or central axial position whereby the push-button is restored to this position when pushed or pulled. In the example of Fig. 4 the cams 90 are shaped so that the push button is urged and held in both the pulled-on and pushed-in positions.
