General Description of Pressure switch ST307-350-B
A range of piston-operated pressure switches for general applications where an electrical signal is needed to indicate a given pressure condition in a hydraulic circuit. The microswitch is actuated by the operating plate of an adjustable loading spring. The spring load holds the operating plate against the switch until applied hydraulic pressure on a small piston forces the operating plate away from the switch to change over the switch contacts. The switch will reset when the hydraulic pressure falls by a small differential.
