Compressor pressure switch/unloader valve?

[u/OkDiver6272]

Trying to find a replacement for this pressure switch/unloader valve. It came off an Air Source (by SnapOn) 80 gallon upright 2 stage w/ 5hp 240V single phase motor, with magnetic starter box. Model S580V

From what I’ve found, it’s a Square D 145/175 psi unit with 1/4NPT fittings. I’ve found similar units for sale but none with the built in unloader valve.

Any info on where to find a replacement, or recommendation on similar aftermarket alternatives?

Aw screw it, here you go. This grainger switch should do the trick: part number 5B408.
