I want to mod my hana dna30

[zamboura]

So i have this Hana DNA30 v3 clone from FT, never had a problem with it. Used it around 7 months now.
But the fire button just popped loose from the case and is damaged.
Im good at doing, i just need the electrical advise. I want to replace the tiny dome tact switch with a 12-16mm blue LED Anti Vandal switch wired so it lights up when pressed(not always on draining battery life).
I saw somewhere i need a resistor for the led, being Blue its around 20mA2.4v, now what resistor would i need? And where would it need to be placed?
Would an Anti-Vandal switch cause an issues with the mods functioning?

I'm not sure what the answer is but you are more likely to find it here:

If there is an external connection for the illumination LEDs you need to place a "Current limiting" resistor in-line with the LED according to the rating on the switch,
Unless the switch have a built in resistor,
This is the best help I can offer you...

By the way this switch has four legs, plus\ minus... and two for the Led, one of which is "on"... the second... only when clicking!

It should fit that box, but you might want to check others mods to get some idea if you have room for a button like that. Hit google and see what others are doing because those buttons sit right on the 510 connection and it's really tight in there.

I have a pretty good idea of how to wire it, i just dont know what resistor i need so the led doesnt fry

Maybe you can use: Resistor Calculator for Leds...
