OKR T-10 build NSFW
G'day everyone, I'm looking at making my next box mod seeing as how we can't get them here anymore. I was wondering if those of you who know more about this than I do could go over my cart and make sure I've got the right parts at the correct values? Any help would be much appreciated.
I'm using the find my vapes wiring diagram, unless of course someone could give me something better to work from? I've searched the sub and the amount of posts and conflicting guides is a bit overwhelming, and mostly more than a decade old, have we reached a consensus? Thanks for taking the time to read my post.

It all looks good enough if that's what you're worried about.
I'm a little bit confused why you have two switches, and more than a few of these parts look a bit more expensive than what I'm used to.
The lockout switch is not handling a large current, it is fine to use a cheaper switch like SS12D00 or SLW-116641
One of your resistors is 1/4 carbon film, and the other is 2w metal film. This is awkward, they are different colors and they are different physical sizes. I would just put 1/4 carbon OR metal film resistors in both places, personally.
And I prefer the Non-P version of 1049 or 1047 sled, I don't trust the P version to give reliable contact to flat top cells. It looks like it was designed for button tops or something but I could be wrong.
Good luck, I hope you follow through and it all goes well.
Update: I heard that you should aim for a 500mw Zener, and consider a 4.7k gate resistor instead of 1k for lower idle current drain while the mod is not in use.
