I made this switch box with an electronics job box, two very high quality Moroso toggle switches with covers, and two 12v LED's. All the wiring, outside the loop connectors, are soldered and heat shrink sealed. It comes with about 10' of wiring for each switch - the arming switch (wired to red LED) and the bottle heater (wired to yellow LED). I have over $40 in supplies and more than an hour making the panel.

$45 shipped.

Here are few pictures lit and unlit:
