Hydraulic Pressure Switches Pressure switches are devices that convert pressure changes into electrical or linear energy based on transducer activation. In a liquid (hydraulic) system, the pressure is developed by continually applying a force to a non-compressible liquid. Figure 5-10 shows a pressure switch. The liquid flows into chamber B and moves piston 2 to the right, actuating the limit to make or break an electrical circuit. The pressure switches are used to issue an electrical switching command or signal for further work steps when a predefined pressure value is reached. The liquid in chamber B is throttled past valve 3 and ball 4 because of the action of the spring behind piston 2. Hydraulic Pressure Switch is extensively appreciated among the masses. Pressure switches used in hydraulic applications typically experience higher pressures, have wider pressure variations, and produce more surges, since the medium does not compress. We distribute and support Omal’s range of process valves.
