If i may suggest, while PM Systems is up and running, see what steps you do there to make the elec light go out there, and then see if you can duplicate it through your switches.
Just out of curiosity, in the phidgets configure panel, have you tried to click the invert button just to test wiring configuration is correct? Just maybe by a small chance could it be grounded and showing "on" all the time?
