Circuit Breaker Box (Smoke Stopper)

The CBB is a compact smoke stopper, only 50mm cubed! It comes in a tall model (60mm Height) as well to give you more room depending on the switch you buy. You can even get fancy and get a switch with a LED! 

If you do choose to go with a LED and you are going to use a 5-6S, get a 24v LED. When plugged into a 3S the LED will just be a little bit dimmer, but still has a good brightness. If you are just using up to a 4S, you can just get a 12v LED. If you get a 1NO1NC switch, you'll need to print the Tall Model as they are longer than the 1NO buttons.

Just some references on push buttons (LED 24v). You can find the push buttons cheaper elsewhere. There are all kinds of styles out there.

Use at least a M2x6 bolt to secure the cover, if you so choose to use one.

You'll need to make a female to female XT60 cable for the output.
