That looks like a pretty plain microswitch. I can't tell from the photo if it's wired normally open or normally closed, but if you follow that linked document you should have no trouble using those.

@surrfman are there any part number labels on the motors? If so then you can look them up online. If not, then I suggest you measure the resistance of one phase; then you can search a stepper motor catalogue for a motor of similar Nema size, length and phase resistance to get a good estimate of the other parameters.

You could also try to identify the stepper motor driver chips on the Raise board, which wold give a good idea of the motor current requirements.

@surrfman a good start point would be to confirm the motor currents used by the N2, along with the heater voltage, temp sensor types etc. If you can get the full config.g from the N2 that will also be useful in the future. With that you can see which Duet mainboard fits the requirement best (after adding a second X axis for the idex.)
