Yes I have an extra switch shown... I can't count.
Step 2: Assemble make kit
I did use a small piece of solderless breadboard instead of soldering right to the make kit,
Step 3: Cut holes for mounting kit
I used a marker to mark the holes in the box.
Step 4: Holes in the side

Step 5: Cut holes for switches

Step 6: Wire the LED
Step 7: Power Switch
Step 8: Toggle Switches
On the kit you send the pins a negative load to activate them. So run negative to the middle, and then two other wires from the switch.
I soldered all three switches off of on piece of wire to make it easier to run the wires.
