Procedure 3.5 - Wire The Horizontal Thruster Control Switches - SeaPerch Remotely Operated Vehicle Construction Manual

OPTIONAL PROCEDURE 3.5 – THREE TOGGLE SWITCHES
Procedure 3.5 – Wire the Horizontal Thruster Control Switches
Tools:
Soldering Iron and Solder
Small Needle-Nose Pliers
Flush Wire-Cutting Pliers
Wire Strippers
Vise or Clamp
Materials:
Control Box with Assembled
Power Cord and Tether Cable
2 DPDT, Center-Off, Toggle
Switches (Momentary Type
Preferred)
Construction Steps:
1. Review Figures 3.5-1, 3.5-2, and 3.5-3 to understand the functions and wiring
of the horizontal thruster controls.
2. Locate the 2" (5 cm) green and blue crisscross wire pairs that you moved
aside in Procedure 3.4, separate pairs, and strip 1/8" to 1/4" (3-6 mm) of
insulation off the ends of all four wires. Set the blue pair wires aside for later
use in wiring the other (port) toggle switch.
3. Secure the "starboard" (right) control switch (or the whole control box if it is
being used as a switch wiring fixture, which can also be taped down on a
tabletop for stability) in a clamp or a vise so that it will be held in a stable
position while you connect and solder the wires.
4. Pick either of the remaining two red (+) wires from your power cord (from
inside the control box), and insert it through the left center terminal on the
toggle switch, being careful to have all of the small strands of wire pass
through the hole in the terminal. Then bend the strands around the terminal
and squeeze them tight using needle-nose pliers, to make a good mechanical
connection, in preparation for soldering. Do not solder the connection yet.
5. Similarly, insert one of the black (–) power wires into the right center terminal
on the toggle switch, and again bend and squeeze the wire tightly to the
terminal.
