Is the white momentary switch the middle click button?
I have a couple of G602's that have failing middle click buttons, and if it's the momentary switch, it looks like an easy fix.

G5 Button was sticking. Followed guide, I did not need spudger. Brushed board and buttons with toothbrush and alcohol. Button works now, thanks!
