We don’t know yet how much Amp the switch can take, or if it is possible to beef up the switch, some of these very small switch assembly’s can really limit max possible Amp, even the bigger one often do
But it is still very interesting possible solution to the question, on where we can find a small aluminum aaa/10440 sized light that modable with a clicky switch instead of the twisty. i hope Jexree will release something similar so we can get some different colors, i am not really sold on the gold one just yet
