- 6x Limit Switch & 6x Wiring Harness
Limit switches usually work with the driver board to provide input signal to computer to tell the computer where the CNC machine limits are.
When the limit reached from an axis, the switch is activated and the computer will stop the machine. You can also use limit switches to inform the computer of the home position.
Usually you will need 6 of these switches for a 3 Axis CNC machine.
