6. Using a well-heated soldering iron,
with a clean, freshly “tinned” tip, solder
just the red-wire (left, center) terminal on the switch, being careful not to use
too much solder (use just enough to flow over the connection) or to overheat
the switch (which could melt internal components, permanently damaging the
switch). For this and all other soldered connections, also be careful not to
create any solder bridges between the terminals, and make sure to snip off
any frayed pieces of wire sticking out toward other terminals on the switch.
7. Wait at least 30 seconds for the switch to cool, and then solder the black-wire
(right, center) terminal on the switch.
8.
Connect one end of the 2” (5 cm)
green & white striped crisscross wire to
the top left terminal of the switch, bending it around the terminal as before,
and similarly connect the other end of the wire to the bottom right terminal.
Do not solder the connections yet .
9. Connect one end of the green crisscross wire to the top right terminal of the
switch, and connect the other end to the bottom left terminal. Do not solder
the connections yet .
10. Check to make sure that all four connections are tight and that the wires are
out of the way of the other terminals, and then solder
only the top two
connections, allowing about 30 seconds between soldering operations.
11. Take the
tether cable’s
green wire pair and untwist it
for about 1” (2.5 cm).
Strip 1/8” to 1/4" (3 to 6 mm) of insulation off the ends of both the
green wire
and the white & green striped wire. Be careful not to nick the wires (which
could cause them to break off later).
12. Insert the green wire into the bottom left terminal on the toggle switch (on the
side that has the red wire on the center terminal), adding it to the green wire
already in place on that terminal, as shown in Figures 3.5-1 and 3.5-3. Bend
and squeeze the wire to the terminal as before. Make sure that no other
terminal is touched by the green pair wires.
13. Solder the two wires on the bottom left terminal.
14. Insert the white & green striped wire from the tether cable into the bottom
right terminal (the one that already has a white & green striped wire
connected), again bending, squeezing it to the terminal, and checking the
connection. Solder the two wires on this terminal.
15. Check all terminals on the switch to make sure that there are no stray wire
strands or solder bridges between the terminals. The wired switch should
look similar to the one shown in Figure 3.5-1.
