We are really looking for someone who can send us a pressure switch, even if its from prior years or anything... If we have to, for the time being we can hard code it like you said, but it would be nice to have the autoshutoff feature =)
Thanks!

Directly connecting the pressure switch to the battery could very probably cause the switch to weld itself shut, causing the exact symptoms that you are describing. The way that FIRST specs the pneumatic system, the switch would be handling milliamps. The way you had it hooked up, the switch would be handling amps, causing damage. If you do get a new switch, be sure that you don't ever connect the switch to anything other than a digital input on the RC, or you more than likely will end up with another dead switch.
EDIT:
From your latest post, it sounds like you 'tested' it with something other than the RC. Even if you only connect the switch that way during testing, it would be permanently destroyed. NEVER connect it to anything besides a digital input. If you _really_ want to test it, you can use an ohmmeter across the terminals without worrying about damaging it. It should go to 'zero' when the switch is closed.
