Speedaire model #3Z406G compressor

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 runtime hours on it. Any suggestions?

Need a Speedaire pressure switch
by: Bill

This one may do the job. It's pressure settings are adjustable.



I cannot tell from any picture I've seen what the complete setup of the pressure switch is.

If this won't do it, start a new thread, refer to this one, and upload closeup images of all sides of the current pressure switch and I'll see if I can find a better one for you.
