Safety switch found on a couple of different mills and lathes. One use is to cut off the Z-Axis power lift motor on the HiTorque deluxe large bench mill. When the Z-Axis is at its upper or lower limit, the sensors send a signal to this safety switch to shut off the Z-Axis power lift motor.

Another use for this switch is to stop the spindle when the change gear cover is opened on the 9x20 bench lathe.
