Abstract

1336016 Mechanical switches JOSEPH LUCAS (INDUSTRIES) Ltd 26 May 1971 [20 June 1970] 30047/70 Heading H1N A switch comprises fixed contacts 23, 24, a slider 14 carrying movable contact 18 which is a snap fit on slider 14, a cam member 25 carried by slider 14 and co-operating with cam follower 28 to releasable retain movable contact 18 bridging fixed contacts 23, 24, and resilient means (a spring) 27 between cam member 25 and movable contact 18 to urge member 25 towards cam follower 28 and movable contact 18 into engagement with fixed contacts 23, 24. Movable contact 18 is U-shaped, its limbs carrying resilient tags 19, Fig. 2 (not shown) snapping over shoulders on slider 14. The switch is push-on, push-off and to do this, cam member 25 has a heart-shaped cam track 31, Fig. 3 (not shown) comprising ramp and steps so that when slider 14 is initially pushed, cam follower 28 is slid down one side of the cam track into engagement with a recess 29d, (Fig. 3), being urged into the recess by retractive spring 30, and when slider 14 is again pushed cam follower 28 emerges from the recess and is slid to its original position.
