Hello #MechanicalkKeyboard, I have an old and loved keyboard with cherry black switches. A few keys, most notably left ctrl, need a "warmup". They won't function out of the box, instead I have to press them intensely for a couple dozen times and then they work again.

What do I need to change/repair to get rid of this behaviour? Is it some kind of cold solder connection or a defect switch or something else? Only affects 2-3 keys, the others are fine.

@Kiki I’d try to rule out a dirt problem first of all - going as far as removing the keycap and checking how it reacts when pressed with a bare finger / if I can see or blow out any debris. If that’s all clear it might be the switch (in which case I’d exchange that one and a working one to see if the error travels along with the switch).

How to replace one depends on what keyboard it is in though.. for non-hotswappables you’ll need some soldering to get it out and a new one in.

@heals thanks! It's likely soldered but that'd be no problem for me.
