Kurt, if you are using an industrial style switch the three wires should be:

1 will be a common wire the other 2 will be 1 NC (normally closed) and the other NO (normally open) both of which will be in the normal state (no Pressure) the trick is to figur the common then OHM out the other two to get the NO open set which you want.
