how to make a waterproof switch for a minisub? Answered
Right now, I am in the process of building a small tethered submarine that is only about 1 foot long. There will be an external light module on it. So far I have a cluster of LEDs and a 9v battery holder that are both waterproof, but I do not have a way of turning the lights on and off that is waterproof. Does anyone have any suggestions on how to waterproof a switch or where to buy a waterproof switch?
