Limit switches are always on.

Yes, we tried using a multimeter and the switches seemed to work just fine.

The inputs pull high (true) when not connected. You need to ground the signal to make it false. The switch should be connected to the white and black.

So... someone on your team played a prank and changed the wiring while you weren't looking?
