Step 4: Solder.

Picture of Solder.
Cut the Perf board until it feels most "comfortable" as a shield. You can use my shape if you want. Make sure it doesn't block the valuable reset button unless it is UNO Version R3...

Then solder from the schematic. Remember. Pin 11 not 10 for highest Ouput Level.

 One Lead from switch One goes to Pin 9. On the other switch, connect Lead 1 to Pin 8. Both switch's pin 2s go to Pin 13 on Arduino. (AKA Ground.)
