There was a thread about this but I can't find it.
I do it the simple way, I solder a resistor to the led+ and wire from the resistor to the out+. A wire from the LED- to the battery-. Always test the buttons led before you install it in the mod saves getting grey hairs

Thanks for the advice.
What size resistor do you use for a blue LED switch?

That all depends on what the max output voltage.
Say the max output voltage is 4.2 volts. Next we need some more info from spec sheet https://www.e-switch.com/system/asset/product_line/data_sheet/7/PV6.pdf Base voltage for LED colors blue, green and white is 2.8V @ 20mA
Now we have all the info we need we can use a led calculator LED calculator for single LEDs

Have you tried running the DNA40 with LED wired like this? I was seriously tempted to put an illuminated 12mm switch that was perfect on my last Hana build but everything I read put me off, the 40 chips are extremely sensitive which got me worried about upsetting the operation with temp sensing. If I am over-complicating the issue that would be good to know.

Eddie you scare me sometimes.
I got a bunch of DNA40 90% of them were bad and had the lock screen bug, I tested them right out of the box before installed them in mods. Some were ok and I installed them in mods with a led button using the simple resistor method and they worked fine, customer got back to me and said there were zero problems.
Sent the bad chips back to evolve and got replacement chips straight from evolve.
Been stressing to get mods made with the new chips I got from evolve, sent a finished mod out to a customer with the resistor led method and guess what..... locked screen after one day of use. This all happened yesterday. So yesterday night I was laid in bed worrying what the hell was up with the new chips I got from evolve (I fully tested them before installing them in mods and tested them again before sending the mods out) and thought it must be the resistor that is causing the problem, logged on here today read Eddie's reply and it gives me hope that it is the resistor causing the problem.
Seems like the simple resistor method will not work with the new DNA40's evolve are sending out.

There was me thinking I was missing a very simple solution! It may not be that causing the issue, but I would keep any extra electronics well away from these boards. I love the thinking and the operation of the DNA's but they are just too damn sensitive. This is why I am steering clear of them for the moment, and I'm an Evolv fan!
The SX on the other hand, I think I could run over one and it would still work!

My thoughts exactly.
After reading countless threads about the DNA40 there seems to be still a lot of bugs and issues. DNA40 is very sensitive compared to past DNA chips and the sx350 (hands down the most robust chip you can buy). Feels like we are beta testers for evolve.....
I should be getting the mod back on Monday so Ill see if the resistor actually broke the new replacement chip from evolve or if its just the resistor causing the chip to bug out.
Well I have the c/f version but it doesn't have the gold sockets like I have seen recently. After installing into my mod and using for a day I got the mirrored screen (message back to front) then later the scrabbled screen. I never wired up the led switch and I still got the problems.
Did the replacement boards you received from evolve have the gold sockets or just the regular silver ones?
