If you are just looking for this pressure switch, you can get something equivalent off amazon or ebay. Just need to make sure the port count and diameters match your machine. And the pressure rating is close to what you need.

if you're talking the pressure switch, they are quite universal. the post above covers it . I will just add that you probably need one with an unloader circuit on it too
curious, how have you diagnosed that it needs a switch?

Pacific air compressors had the best price when I needed a pressure switch for my forty-year-old compressor. I used their eBay store.

I have a 5 hp DeVibliss that is at least 50 years old. I had to rebuild the unloader valve on it a few years back, and DeVibiss did me well with a parts kit for (IIRC) ~$20. Should be good for another 50 years of startling the hell out of anyone in the shop when it starts up (it's a back-up for the near-silent IR scroll comp)! I call the old comp "Operation Arc Light" as that's what it sounds like. https://en.wikipedia.org/wiki/Operation_Arc_Light for you youngsters.
Sorry it took me so long to respond but I got some pics and as for diagnosing it well it was pretty easy, the switch lever was gone lol. It probably has more issues than that but one thing at a time right.

Something like this?

This came up as a google search. Using
DeVilbiss Pro 4000 20 Gal 3.5hp pressure switch
As the search term.

looks like you need a 4 port switch with 1/4 npt threads, shut off @ 125psi, with an unloader valve
If you're unsure of the condition of it, I would by pass the switch and do a quick test to see how everything else is, like does it build pressure, does it leak, especially the tank, how does it sound, etc. no sense tossing money at it if it has tank or major issues.

Dump it now. That was the first air compressor I ever bought, I think it came from either Price Club (what Costco used to be called) or Sam's Club. Once you turn it on you will hear a sound that will quickly deafen you. These were the first generation of oil-less compressors and they made a 747 at takeoff sound quite.
Ya my dad and us kids used it all the time growing up. It is very loud lol. But other than it only supplying 40psi at the nozzle it seems to be better than most other compressor I could get at the stores today for less than $300. Like the CFM is 11.9 and the HP is a 3.5, that and I am a cheap sob lol. But also nostalgia and all because it was my Dads

If it's oil-less, I agree with "dump it now". IME, oil-less comps rapidly become air-less compressors. The bottom of the piston is open to unfiltered air and dust and the piston and cylinder get scored but fast. The construction crew I worked on years ago quit buying them after going through two in one season from jobsite dust.
