Damaged Cherry Brown Switch

[Terminator_]

I'm really not sure what happened or whats wrong with the 5 key on my Logitech G610 Cherry Brown, had the keyboard a year now
They switch takes far more force now, still gives a the noticeable activation click feel, and after pressing it down fully, it slowly rises again
Anyone one got any ideas what I could try to fix this?
Cheers

Sounds like something sticky got under the key. You can replace the key, if it's just standard Cherry switches, but you need to take apart the keyboard and likely do a bit of soldering.
