Abstract
1,162,288. Snap-action switches. CUTLERHAMMER Inc. 11 Dec., 1967 [9 Dec., 1966], No. 56209/67. Heading H1N. In a snap-action electric switch a trifurcated contact blade 18d, Fig. 2, has a pair of compression legs 18c, Fig. 2, extending from a region near the contact 18a to a pivot point p and a compression leg 18e bent over at its other end and extending to a second pivot point 18f whereby the operating plunger 6 is yieldingly restrained throughout its range of movement. The pivot points are arranged on a common bent-up terminal 16 which is slotted to receive a locating tongue 18f of the contact blade and has tongues 16e for location in recesses of the base 2 and cover 4 (not shown). A cover attachment rivet 8 may carry a pivoted actuator.
