Abstract

1,189,971. Snap-action switches. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 Jan., 1969, No. 4580/69. Heading H1N. A snap-action switch comprises a cantilever mounted trifurcated switch blade 1, 3 incorporating a toggle spring 4 and carrying a moving contact 13 and a pair of spaced switch operating members 15, 16, each adapted to move substantially in a plane normal to the plane of the blade 1 for snapping the blade from one stable position to the other for making and breaking contact with fixed contact 10. As shown, the switch-operating members 15, 16 form part of rocker 14 but it is stated that a pair of push-buttons may be used. Spring blade 1, 3 is held in position by a clip 8. In a modification, Figs. 4-7 (not shown), the toggle spring 4 is inverted and its base contacts the bottom of the casing during the switching operation so that spring 4 rolls on the bottom of the casing during operation, which is stated to have the advantage that larger tolerances on spring force for both blade 1 and toggle spring 4 can be accommodated to offset variations due to manufacturing tolerances.
