United StatesOnly bought this to replace old one.
United StatesProblems with my compressor not turning on after 2 years. Customer service helped troubleshoot and discovered it was a bad pressure switch. A $30 repair rather than a few hundred for a new compressor.
United StatesThe switch works great, as always. If I was set out to improve it, I would definitely make the leads longer. They are so short, it's hard to splice them.
United StatesThis item works great
