Abstract
575,193. Snap-action switches. PACKMAN, P. J. March 2, 1944, No. 3936. [Class 38 (v)] In a manually operated snap-action switch, two discs 4, 4 are rotatably mounted on the ends of a length of wire 5 coiled to form a spring 6 about a stud 7 which is carried bv a bar 8 (part only shown). The bar 8 is slidably mounted in a cover (not shown) and when it is pushed to the right the discs 4 separate further against the spring tension round the moving contact disc 2 until the latter snaps to the left to contact a stop 3 and cease bridging fixed contacts, 1, 1. When the bar 8 is pushed to the left, the discs 4 again ride round the moving contact disc 2 which moves to the right to bridge contacts 1, 1 with a snap. Modifications of the switch are described in which the moving contact may be a cylinder or sphere, the fixed contacts may be spring members engaging either the curved or flat faces of the moving contact, further fixed contacts may replace the stop 3 to form a two-way switch, and the slide member 8 may be moved by a pivoted lever or a fingeroperated button projecting through the cover.
