Repairing a Compressor Pressure Switch

My air compressor stopped turning on, and tearing into the pressure switch showed exactly why — a melted neutral wire and a charred switch after about 12-13 years of service. I couldn't find an exact replacement, but found a better-built metal-internals switch for a bit more money, then replaced the damaged wiring between the switch and motor and re-plumbed the pressure relief fittings to match. A quick safety note if you're thinking about doing this yourself: compressors combine high pressure and live electrical components, so know what you're doing before you open one up.
