The pressure switch on my Speedaire model 3Z406G (1-hp)has failed. I need to replace it but finding the exact replacement part is impossible. I need to substitute another p-switch (100psi max)complete with unloader valve. Yes, the compressor is old but it doesn't have more than a couple of hundred run time hours on it.


Any suggestions? - See more at: http://www.about-air-compressors.com/speedaire-model-3z406g.html#sthash.tU5Sihp4.dpuf

I have attached a few photos of the failed switch. Thanks, Rich.

Google is your friend.

I find several sources for subs as well as this exact part for $15.
