Abstract

350,229. Snap-action switches. GUINOT, H. R., Ciel, near Verdun-sur-le- Doubs, Sa¶ne-et-Loire, France. June 4, 1930, No. 17186. [Class 38 (v).] Pneumatic actuation.-A pressureoperated snapaction switch has a membrane F1, subject to fluid pressure, and connected by means of a screwed stem T to a sleeve m. The sleeve m is connected through a transverse spring R2 to a stirrup L mounted on a movable contact-arm D pivoted at A and having a spring R to provide a quick action. Movable contacts P on the arm D co-operate with mercury cups G. A spring R1 opposes the action of the diaphragm F1 and the pressure at which the switch operates is varied by screwing the stem T relative to the sleeve m. In a modification, a spring lever mounted on the casing has a forked end which engages the stem T under the sleeve m and may be held by a cam to keep the switch in the open position.
