I’ve got an LED on off switch which has a max of 3v. The battery pack is 37.8v. Could someone talk me through what resistor I need?
This is the switch I’ve got:
Do I need more than 1 resistor? I can’t imagine there’s 1 resistor that will do from 42v to 3v!? Any advice would be really appreciated.
I’d probably want to get a small PCB as well to wire everything in. Recommendations appreciated.
