First budget 18650 light - Solarforce?

I just got those switches. I used one (well 2 since I butchered the first) in a Maglite mod. The traces on the circuit board seem to pull off very easily. I haven't finished yet (ie. haven't fired it up on the new switch), but my Mag was drawing around 1.6A from (2) 18650's.

I too would like to hear why.
