Abstract

1437148 Touchswitch-tactile feedback ILLINOIS TOOL WORKS Inc 30 Sept 1974 [4 Oct 1974] 42308/74 Heading GIN The invention relates to a push action providing tactile feedback (and audible proof of actuation), for a non-mechanical electrical switch, such as an electronic or saturable magnetic "switch". As shown, Figs. 1, 4, 8, the actuating plunger 24 has a cam track 42 formed at one side. The track is engaged by a cylindrical follower 46 at the end of a resilient arm 44 mounted a sliding carrier 26. The carrier is guided by lugs 34, 36 on top of the switch housing 22, and normally biased against stop 40 by spring 58. On depression of the actuating plunger 24 cam follower 46 rides along the face 72 forcing the carrier to the right until at the cam corner point 66 it snaps back. On release of the button 24 the follower 46 rides up the ramp 86 (flexing the resilient arm 44) until it drops back in the track at point 70.
