## Questions & Answers

**Q: will this fit a craftsman 26 gal 1.5hp 150psi compressor?  i am lost!**
A: I may fit but the real question might be is this to big for your compressor. I used it a large 10 HP unit with hi start amp, found requirements on internet somewhere?

**Q: does this switch have an unloader?**
A: I think it’s just the switch. It’s shuts off at 175psi. If it fails, I have 2 200psi valves on the compressor the should release. If all 3 fail, stand back and watch the show. I figure the odds of all 3 failing are minimal.

**Q: is the pressure cut out psi adjustable?  I would like to have a cut out around 130-150**
A: Yes you can adjust both cut out and cut in pressure.

**Q: Sirbe para 240votios**
A: Yes
