Abstract
884,686. Fluid actuation of switches. CONTROLS CO. OF AMERICA. Dec. 8, 1959, No. 41761/59. Class 38 (5). The operating pressure of a diaphragmoperated switch is set by a cam 10 acting on a spring 11, the contacts being reset each time the adjustment is changed. The diaphragm 8 acts through a stud 22 on a toggle action snap switch 7, the movement .of the stud being opposed by the spring 11. The latter is housed in a plunger 37 which is acted upon by an adjustable screw 57 in a spring arm 51 bearing against the cam. The cam has three depres-. sions 49 at different radii from its axis 47 so that three different pressures can be set. Between the depressions are lobes 50 which on changing from one setting to another depress the plunger 37 so that a part 41 thereof depresses the stud 22 to shift the moving contact 29 from its lower to its upper position.
