Switch ?

[Foxman]

OK I'm making my first mod. It's a wood box mod and want to go simple 18650 w/push-switch and 510 connector. If I get a lighted switch would I still need a resistor? If so which one? Thanx

really it depends on the switch and also the color. If you post the switch your going to use and the color or the LED i can calculate a resistor value for you.

thats a latching switch which means you push it once to turn it on and it stay on till pressed again. You are going to want a momentary switch for a PV . there also is no data sheet but i believe that switch is set up for `12 volts . so a built in resistor is more then likely the case. It might light up @ 4.2 volts but it would be pretty dim

So If I get one thats rated 3A lets say, then can you do it from there?
