Abstract

1,096,515. Snap-action switches. MALLORY BATTERIES Ltd. Feb. 15, 1966 [March 4. 1965], No. 6520/66. Heading H2B. A contact arm 33 movable between fixed contacts 25, 30 is connected to an actuating blade 11 by an over-centre spring 34. The blade 11 has a cam follower 16 carrying abutments 18, 19 spaced on either side of a blade 15, whose free end 15<SP>1</SP> is restrained by stops 20, 21. The arrangement is such that as the blade 11 is moved up from the Fig. 2 position it moves the spring 34 over-centre and also straightens the blade 15, the end 15<SP>1</SP> of which thus moves leftwards to intercept the movement of arm 33 in a central " open " position. Further, movement of blade 11 causes the end 15<SP>1</SP> to move to the right to release the arm 33 which moves to its lower position. The parts are biased to the Fig. 2 position by a spring 39. Casing 12 has snap-in mounting posts 45, 46.
