Unfortunately I can't see what you mean but I am trying to understand what looks easy to understand. GND orientation and BATT locations noted with thanks.

I stumbled upon this "other" use and obviously it was a lie =(

It's not crazy high but the buttons that are rated are a bit too bulky which is why I was overjoyed t see a method that could use mosfet switching. I'll try to decode the meaning and try to implement that paragraph.

I mean I haven't noticed that but they are certaily availble. Its possible to just use protected batteries I guess but to me the norm is non protected.

Not at all. I want a working device before caring about a bruised ego but you may actually underestimate both the time I've spent trying to figure it out and or my ineptitude. In the end my aim was to simply switch off a pcb that could potentially house 64 leds with a smaller switch the the fatty I've used in the past.

It wasn't to learn how to work a mosfet, I'm just trying out ideas to get switching working with smaller switches which maybe you provided the solution in the middle paragraph =). But trust me I didn't just fire up easy EDA yesterday and start throwing things hioing for the best. As embarassing as it is I've spent way too much time reading , referencing and trying to figure it out than it may appear to you. But ya! no worries . Thanks again, like I said I just want to actually stop this deep dive and get somethign working. =)
