Staring at the pressure switch some more I see the spring I labled
"B" does nothing. there is a screw post with a pin thru it
on which rests a flat washer, a smaller washer then the spring, then
a cup washer and the nut. the lever from the contacts is above the
washers and never makes contact with the spring or other parts. If
anyone has a similar switch and can take a picture and either post it
or e-mail to kd006(at)yahoo.com I just may be able to figure this out.


Thanks

That is called an "unloader" valve. It releases the pressure off the
discharge line so the compressor can start back up easier.
