Abstract

641,283. Snap-action switches. WALTER INSTRUMENTS, Ltd., NOAD, J. E. G., and ARMSTRONG, C. J. Jan. 15, 1948, No. 1335. Drawings to Specification. [Class 38(v)] A snap-action rotary switch has a spring which is strained by an actuating member until a flexible detent carried by a movable switch member is disengaged from a fixed stop by a release member movable with the actuating member. The spring then moves the switch member with a snap into its next position. The specific embodiment of the invention is that described in Specification 641,282.
