Wiring the Limit Switches
Mount the leg limit switches to the mounting brackets labeled G
and H with appropriately sized machine screws and nuts, orient-
ed as shown in Figure 6.22. Cut four wires to a length of 8 inch-
es. Solder two of these wires to a 2-connector female header.
Locate another 2-connector female header and solder the other
two wires to it. Protect each of the connections with a 1/4-inch
length of heat-shrink tubing. Cut two more wires to a length of 5
inches. Wire up the leg limit switches, as shown in Figure 6.22.
The finished leg limit switches with connectors and mounting
brackets are shown in Figure 6.23. Attach the mounting brackets
with the limit switches to the bottom of the chassis using four
6/32-inch 1/2-inch machine screws and locking nuts, as shown
in Figure 6.24.
