Abstract

1486131 Retractive switches OTTO ENG Inc 7 Jan 1975 [4 Feb 1974] 626/75 Heading H1N A miniature snap-action microswitch comprises an elongated generally planar switch blade 42 having a movable contact portion 44 biased towards one position and having one or more depressed portions 48 bent to lie below the general plane of the blade, the biasing means causing a tensile force tending to straighten the or each depressed portion, and actuating means 56 which moves the or each depressed portion of the blade to cause the contact portion to snap over. As shown the blade comprises a pair of spaced apart legs 45, 46 extending between end portions 43 and 44 and each leg has a depressed portion 48 and a raised portion 49. The biasing means comprises a struck out integral tongue 47 and an opening 52 at each side of the base of the tongue has a diameter at least five times the thickness of the blade. Flanges 53 increase the stiffness of contact portion 44. The actuator 56 has a central extension 65 guided between the blade legs while lateral extensions 64 (and 63, Fig. 9, not shown) act on the depressed portions 48.
