I recently ordered these switches (2 x AC 250V/6A, 125V/10A SPDT On-Off-ON), and was wondering if I could use them in my 12V ammo can boombox build? This will be used to choose from wall power (provided via a wall wart), or battery power (12v 4800mAh).

 

I think that would be fine, although folks recommend NOT using an AC switch with DC. So it would be better to find an automotive or marine switch meant for DC.
