    I need to wire in a pressure switch with a NO and NC switch in it. When the pressure goes over a certain pressure, I want it where you have to push the reset button before it will turn the compressor that it's controlling back on. It's in a 120v circuit. I think I need a relay but not exactly sure how to wire it in. Any suggestions would be appreciated.

    Have a look at the attached schematic.

    You'll need a NO pushbutton switch and a 120v relay with at least DPST NO contacts, but DPDT will also work.

    Use wire nuts for your connections. Electrical tape will get gummy over time and fall off.

    [Edited to change depiction of pressure switch from NO to NC]
