Abstract
893,181. Fluid actuation of switches. AEROTIC INDUSTRIES Inc. April 14, 1960, No. 13501/60. Class 38 (5). A pressure-actuated switch comprises a cylindrical chamber 10 containing a cylindrical block 20 of elastomeric material having the same diameter as that of the chamber 10. An inlet 12 for pressure fluid is provided at one end of the chamber 10 and the other end is closed by a plate 14 in which a stem 22 is slidable against the operating member 23 of a micro-switch 24 mounted on the plate 14. Pressure exerted via inlet 12 seals the block 20 against chamber 10 and also distorts the block to move the stem 22 and operate switch 24. The stem 22 has a flanged head 21 to limit its movement and prevent damage due to excessive pressure. The block 20 may have a protective outer covering (Fig. 4, not shown), if the pressure fluid is such as may attack the material of the block. The end of the block 20 exposed to the pressure fluid may be rounded convexly (Fig. 5, not shown), to improve the sealing of the block to the chamber 10.
