Dying key – mechanical

[D-Dan]

I have a Cooolermaster Trigger mech keyboard and just lately, the comma key is dead, sometimes. Tonight, I’ve popped it off and cleaned it out. I have no compressed air for a full job, but there’s no obvious contamination that would cause this.

It seems to be a little better, now, but are there any tips for getting it back up to full working order (it’s not dead, as this post demonstrates, but it seems I have to hit it just right).

No other keys exhibiting problems, so I’d rather not replace.

Arch Linux, on a Ryzen 7 1800X, 32 GB, 5 (yes -5) HDs inc 5 SSDs, 4 RPi 3Bs + 1 RPi 4B - one as an NFS server with two more drives, PiHole (shut yours), Plex server, cloud server, and other random Pi stuff. Nice CoolerMaster case, 2 x NV GTX 1070 8GB, and a whopping 32" AOC 1440P monitor.

Oh, had an idea. Popped it off again and gave it a good brushing with a (clean) pastry brush. Seems to be working OK, now.

Hi Dan
What you need is a fibreglass pencil, they are designed for cleaning contacts on PCBs.
Maybe a bit of Contact Cleaner would help your “pastry brush”, try Maplin.
