Need help with my air compressor

[Big Ray]

So I was planning on working on the murderano after work today. Couldn't find my dremel kit, so I switched to plan b using the air cutof wheel. Cranked up the compressor and lo and behold it won't shut off. Got to 160 psi!

Naturally, the switch is now obsolete. I need guidance rigging an alternative. As always, thanks in advance!

I have a condor mdr 11/11 for a single phase 240v 30a with unloader valve. I believe its on at 90psi, off at 135psi. Im sure it will work with 120v as well up to 30 amps, its not energizing a coil.
