That does sound like a problem. I misunderstood the spark and motor trying to start part...

In any case a magnetic motor starter may solve the problem of killing pressure switches.

I equipped my compressors with surplus electrical stuff including Square D pressure switches from eBay at quite reasonable prices. May take some research and understanding to ensure you get what you need.
