Abstract

1,099,048. Snap-action switches. A. B. METAL PRODUCTS Ltd. Sept. 9, 1966, No. 40467/66. Heading H2B. A switch comprises moving contact arms 7, 8, pivotally mounted intermediate their ends for rocking movement on spring supporting members 5, 6, and rotary actuating means including a cam 3 on a pivot 3a and rotatable between the spring members 5, 6, to part them against their own resilience and then to rock the arms 7, 8, to contact fixed contacts 9, 10. Cam 3 moves through an arc limited by abutments 13 on the cam engaging a projection 14 of the switch body 4. Reverse rotation of the cam 3 disengages contact arms 7, 8, from contacts 9, 10. The cam 3 is operated by an actuating projection (2a) on the rotor (2) of a rotary potentiometer engaging lugs 11 on the cam 3, (see Figs. 2, 3, not shown). The contact arms 7, 8, are notched for pivotal co-operation with the forked ends of the spring supports 5, 6, as in Specification 918,569.
