#Broken power switch shield

On my IPS 3.0 build that I'm putting together, the power switch is really sensitive, touching it caused either flickering or the power shutting off. I attempted to clean it several times, removed and resoldered the shield, it was a little better but it still didn't work. On my final attempt the shield broke apart a little. What should I do now?

I'm considering buying a new switch on AliExpress but I've never done a soldering job like that before (only soldered small wires to ribbons and motherboards).

im hesitant to recommend something like this but, if you're willing to replace the switch anyway:
if you can prove that the switch works correctly when you hold down the broken side of the shield, you could glue the broken side down. you'd need to be very careful to avoid the glue getting inside.

I'd approach it by soldering down the good side and using a tiny dot of superglue on the snapped side whilst pressing down hard for a couple of minutes on the shield. you want to use the smallest amount possible to avoid it seeping inside

#

you need to scrub that switch harder. get a cotton bud and cut it in half so you have the paper stick end exposed, use ipa and SCRUB those metal contacts. it will make a horrible noise if you're doing it right. every so often cut off a little bit of the cardboard tube to expose a fresh end

The shield doesn't have to be soldered to the board on both sides for the power switch to work?

#

If not, that's good to know! Thank you for this advice! I'll try it when I get a chance! Like you said, I'm considering replacing the switch anyway so no harm in trying this.

If you decide to use superglue, I'd recommend testing the consistency of your particular glue. Not all behave completely the same, there's thick, gel like ones, there's super thin, liquid-y, spready ones (usually marked as such) but also everything in between and not marked in any special way. With superglue, it always helps to do a dry run first, see how easily you could be applying it, and hold it in place. Same with the glue, try it on some similar enough materials to see how much it will spread and become a mess around the spot. (And yes, in this instance, I think superglue's a reasonable choice.)

I tried this because I had it lying around but no dice

It wouldn't stick properly. Was able to clean it up nicely though.

Also tried cutting a very thin piece of double sided 3m tape and stick it on well, but it didn't hold either 😆

2 part epoxy will definitely work if you clean up the surfaces, but you'll need to find a way to keep the metal piece held down whilst it cures

Ahh I see... maybe just need to find a way to let it harden without it popping off 🤔

Exactly, you have to hold it in place until the glue hardens

Thank you everyone. I was able to fix the issue by using cyanoacrylate adhesive. I let it dry as suggested (overnight) while holding the shield down with an object placed on it.

I'm not sure how long this will last but hopefully quite a while! I have some backup switches now just in case.

#

Probably could have cleaned it up by removing the solder and excess glue but I just wanted to get it working.

Also need to recharge my batteries 😆
