19.9 - There are three limit switches, one each for the three towers. Each switch is installed
using two #2-56 5/8" machine screws and two #2-56 nuts. The switches are wired as Normally Closed.
The end-stop wires should be attached to the "C" and "NC" terminals. In the photo below, these
terminals are on the left (C) and right (NC) of the switch.

shown in the photo.

19.11 -Bending the leads ensures that you'll be able to push on the spade lug connectors later
on. Please make sure that before you bend the leads on the switch that you’re bending them in
the correct direction! Do this by holding the switch so the Common leg is on the end closest to
the center of the machine. Raise the axis you’re going to install the switch on and bend the
leads such that when the switch is installed on one of the INSIDE faces of the Idler Bracket, the
End Stop Adjustment Screw will engage the end of the switch lever when it travels to the top.
