You have the idea - but not quite right.
You do not need any 5v supply - this is provided internally by the computer on pin 12
A quick diagram is provided.
As Hood says - you can shield the cable if you require - you can use solid copper if you wish - there should not be any movement - fasten the switch to the frame of the mill and let the carriage operate it.
Hood also says you can , when you configure the switches, have them act as limit switches as well. This would be a good idea, you dont want the carriage to go beyond the switches or they will be damaged.
