Help with led4power switch

Flashlight Modding and DIY Parts

A while ago I cut open one of these tail switch modules and like real dummy cut into the pcb’s and some of the traces. I have a project for it now but since they are discontinued I need to repair this one. I don’t really enjoy soldering but it’s part of the hobby so I try it now and then :person_facepalming:

I think this is the smallest soldering I’ve ever attempted. After soldering (which tested both my ability and patience) I connected power and only 4 leds (every second led) lit up. I thought maybe I had a dodgy solder so tried again… and again only to have the same 4 leds light up.

So on closer inspection I found I had cut another trace on the under side. There wasn’t much space but I got it soldered. Connected power …. nothing…. none of the leds lit up :person_facepalming:

So I removed the wire on the under side and got the 4 leds to light up again.

Anyone know how the wiring should be? or have any advice/tips ? Even if you have a spare I can buy from you…. :innocent:

Bump.

pinkpanda, have you reached Neven concerning this?
I can’t help as I never had any of these switches, but being the “maker” maybe he can help!

Good luck :wink:

Yeh, I sent him an email about 5 days ago but he hasn’t replied.

Its hard to tell if all your connections are good but it looks like you have the right idea.
Try using a small single stranded wire that you can pre bend to just the right arc. You might even reflow the wire on instead of with the iron.
Cut the leads off something like this trim and bend to fit and give it another shot. The smaller the better.

Thanks for the suggestion moderator. Neven has since gotten back to me and said he switch is beyond repair. :weary:

He didn’t explain further but I’m guessing I cut a trace sandwiched in the pcb or something.

So unless someone has one kicking around their parts box I’m going to have to rethink my idea.
