Do you mean the limit switches? I wonder if they work like on an arduino/ramps combo with pull up resistors (Which you can toggle on/off) I know the inputs from the microswitches are 5v on the arduino as I had to use resistors to get the 12v from the inductive sensor down to 5v so I didn't fry the arduino and disable the pullup resistors. But when you use microswitches you have pullup resistors enabled and wire direct.

I do have an inductive probe that works reliably at 5v but running at 5v's reduces the detection distance so I would use a chunkier probe at 12v if I go this route.

I think though decent quality microswitches fitted properly will have high enough accuracy I wouldn't see a difference in real world performance.
