I'm sure this has been posted before (but I've looked without success)...could someone post or PM me a schematic and parts list for a 3.7v 3A n-gate mosfet switch cct. (I want to gate it with a carbon switch, the type found in a Wii contoller)...I've tried to follow some Youtube vids on it but they seem to spend more time on how to strip wire and solder more than anything...please, any help would really be appreciated...
