Need some advice, I'm building a large scale Corsair and am installing a PowerBox sensor switch with 2 Duralite Plus lithium ion 2150 mah Batt. I would like to conceal the PowerBox sensor switch inside the fuselage. Is it possible to wire in a smaller on/off switch to be installed on the outside of the fuselage to turn on and off the system and still keep the integrity of the PowerBox sensor switch? Any help will be appreciated and Thanks, Larry
