the fix is (sort of) easy, though a little unprofessional
attach a ground wire with a 150ohm-ish resistor(thats what we used) to the signal pin, and have the switch connect the positive pin as normal
this wil cause the voltage to always be negative if the switch is disconnected, and when it is connected, mostly positive
you might want to play around with the resistor ohms to get a good mix
hope that helped

Alas, this is not the problem. I'm getting the variable results when the signal is tied to +5. Not just when the switch is open. Tying the signal to +5 should always be a 1. I understand the use of a pull-up/pull_down resister and we will use one when we wire up or control panel. Hard wiring the signal to +5 is what we are doing now, however and we're still getting the problem.
