I'm thinking it returns a "1" if you do close them, there is an indicator LED on the RC, too bad I don't have access to the "robot room" today to test this. I attached a banner sensor once, though, to a digital input and it indicated the switch variable was equal to "1" when the banner sensor detected white, that was of course with the white wire from the banner sensor..... oh well I'll figure out what it does tomorrow lol
