Abstract

1440250 Spring units; toggles INTERNATIONAL STANDARD ELECTRIC CORP 19 June 1973 [20 June 1972] 28944/73 Headings F2S and F2K [Also in Division H1] A snap-acting device has a spring 6 is constrained between points 4, 8 of members 1 and 7 which are movable toward one another to arch the spring and stop surfaces 2, 3 are symmetrically arranged on each side of the spring in the member to constrain the arching so that as the member 7 approaches the member 1 the spring moves as shown in Figs. 3a to 3e. On release of the member 7, which may be a push-button, it moves to the Fig. 3f position ready for a reverse (mirror image) movement next time the pushbutton is depressed. The lower point 4 of the spring 6 may be clamped in the member 8 (Fig. 2b, not shown) or mounted in a rotatable spindle (Fig. 2c, not shown) of a shutter. The spring may carry contacts which cooperate with contacts on the member 8 or may move a shutter of a photoelectric switch.
