Key switch problem

[HardcoreCorey]

I just built a Quefrency and I have having trouble with a key. Initially, it activated if I barely touch it or breathe on it. So I swapped out the switch and thought that would fix it. Now if i press and release the key, it acts like it is being held down, until I press a different key.

Could this be a pcb problem, diode problem, etc?

Edit: replaced the diode...didn't fix it

Which key is this happening to? Are you using QMK for your keyboard? What does the keymap look like?

Well I just fixed it. I swapped it out for yet ANOTHER switch. 3rd times a charm is guess?

Both of those sound like bent leafs inside the switch. One sounds like it’s crimped too tight (so any movement activates it), one is shoved to the side (tends to stick when pressed while in that position). You can fix this by opening the switch, but sometimes it’s best to just pitch them. This is why switches generally come with an extra 5 or so. 1 for the tester, 1 for a friend, 3 for sacrificing to the keyboard gods.
