Abstract
1472475 Toggles; spring units BK PATENT DEVELOPMENT Inc 10 May 1974 [14 May 1973 23 Nov 1973] 20711/74 Headings F2K and F2S [Also in Division H1] The blade 4 of Figs. 1 and 2 is stressed by a bolt 22 so that it has two stable positions, downward movement of the inner arms 12, 14 by actuator 42 applied to cantilever 36 causing the blade to snap upwards to break contact with stop 44 and make contact with stop 46, a spacer (34, Fig. 3, not shown) being provided between the cantilever 36 and the arms 12, 14 to allow the blade to flex and electric contacts being provided (Fig. 16, not shown) on one or both stops and on the blade for use as an electric switch. Further embodiments include one in which the cantilever is replaced by a push button (Figs. 5 to 7, not shown), one in which the arms 12, 14 are mounted on an arm (82, Figs. 13 to 15, not shown) and the stops are mounted on the cantilever, and one in which the contacts are mounted on a T-shaped extension of the end 10 of the blade. An embodiment using an alternative form of blade is shown in Fig. 22; this can be actuated by a single actuator 190, or by two actuators 190, 192 as shown. The stops can be adjustably mounted, e.g. by a screw thread.
