1. Arduino Switch Soldering
The three switches in place and the resistors tied to the switches prior to soldering.

2. Arduino Switch Soldering
The wire to join up all the common terminals on the switches is made from a length of multistrand wire and will need to be stripped as shown.
Greg Moore 2012 Folding the switch tunnel

3. Arduino Switch Soldering
The multistrand wire stripped and twisted tight in the strands and ready to solder across the switch common terminals.
Greg Moore 2012 Folding the switch tunnel

4. Arduino Switch Soldering
The wire now solderered into place across the common terminals.
Greg Moore 2012 Folding the switch tunnel

5. Arduino Switch Soldering
Resistors soldered, and bridging wire soldered, no excess wire trimmed at this point.

6. Arduino Switch Soldering
Close up view of the soldering. Note some non-wet areas of soldering on the bridging wire. These will be corrected.
Greg Moore 2012 Folding the switch tunnel

7. Arduino Switch Soldering
Excess wires will need trimming after the soldering process. Careful attention to no short circuits at this point.
Greg Moore 2012 Folding the switch tunnel

8. Arduino Switch Soldering
The first switch wire is added to the end of the 180 ohm resistor. Twisted carefully for mechanical strength, then soldered.

9. Arduino Switch Soldering
Leave about 15mm for the wire to resistor overlap of lead and wire from resistor.

10. Arduino Switch Soldering
A length of heat shrink tubing has been attached over the wire and joint. Continue to press it down and cover the switch terminal also. Finally, the heat gun will allow the tubing to pull down tight.
Greg Moore 2012 Folding the switch tunnel

11. Arduino Switch Soldering
This heat shrink tubing should have been pushed down to cover the switch terminal. Be careful to avoid this mistake.

12. Arduino Switch Soldering
Another view of the heatshrink tubing, showing the error.. Too short, does not cover the switch terminal.
Greg Moore 2012 Folding the switch tunnel

13. Arduino Switch Soldering
The second switch wire soldered to the 330ohm resistor and heat shrink tubing over. Note the switch terminal covered also.

14. Arduino Switch Soldering
Heat shrink tube covers the 4.7k ohm resistors including the connected switch contact.
Greg Moore 2012 Folding the switch tunnel

15. Arduino Switch Soldering
Close up of the resistors with heat shrink tube. Also, note the bridging wire to the switches is not yet trimmed.

16. Arduino Switch Soldering
The three 4.7k ohm resistors tied together prior to soldering with the connecting wire.
Greg Moore 2012 Folding the switch tunnel

17. Arduino Switch Soldering
The red wire now soldered to the 3 resistors and insulated with heat shrink tube.
Greg Moore 2012 Folding the switch tunnel

18. Arduino Switch Soldering
All the wires and heatshrink in place. The switch wires formed into a loom.

19. Arduino Switch Soldering
Very important to insulate all conectors and soldered connections. This is a very reliable switchbox now. Neat and done in a professional manner.
