I got the momentary on/off switch listed and it's Normally Open, as listed in supplies. Did I need Normally Closed? The power is on without the button being pressed.
I just built one of these and let me just say...absolutely awesome design!
I did have one problem, but Im dealing with it for now. I got the parts from Radio Shack(Is it still called that? I thought it was changed). The only 2xAA battery box they had, had the lid separate about halfway in the middle of the box, so the lid was about the same dimensions as the other half of the box, instead of being basically flat. For the most part this did not present a problem, except when drilling the hole for the atty connector. The hole basically went edge to edge on the box, and after pressing in the connector, it kindof warped the box, so that when you put the lid on, it doesn't sit perfectly flush.
on your battery box, would drilling the atty hole work better on the other end of the box.....
Why go to all the trouble of building a mod, then use a cheap, vastly under rated switch?
Because at 3.7v you don't need a platinum\aerospace made switch, and mostly because it fits just right and lasts\works almost forever.
I tried some of those so called better made switches for $6.50 on my 5v box and they stop working after a few months, oddly enough when I installed a $2 switch it out performed. If need be I can install 2 more and still be under $6.50.
Quality is good, but it must fit the project plans & budget.
(just from my expirience)
Thank you,
