What is the PSI of a pressure switch?
Use in medium-pressure applications up to 540 psi. Switches are rated NEMA 7 and NEMA 9 and meet Class I, Divisions 1 and 2, Groups A, B, C, and D; and Class II, Divisions 1 and 2, Groups E, F, and G for use in hazardous environments.
How does a medium pressure pump switch work?
These switches meet the pressure and electrical requirements of well water pumps. These medium-pressure switches electrically activate automated controls or alarms when a set pressure is reached. A clear cover allows you to see if the switch is on or off. Use in high-pressure applications up to 20, 000 psi.
How do you change the setpoint of a pressure switch?

What kind of pressure switch does Square D air compressor use?
If your compressor does not require a unloader valve on the pressure switch you can leave it not hooked up and the switch will still function properly. This is an authentic Square D brand pressure switch, for more specifications see below.
Can a medium pressure switch be wired on or off?
These medium-pressure switches electrically activate automated controls or alarms when a set pressure is reached. They are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC). Switches are rated NEMA 1 for indoor use.
