I have broken a pad SW1 (again)

Hello!

I have broken my second Anywhere MX 1 mouse when replacing the SW1. The pad broke again near R6 (signal one, the ground is fine) and I was certain to not break it again. But it happened.

Is there any chance that anyone has got the schema or idea where the signal comes from? I would love to make a jumper and get my favorite mouse to work.

I've edited my post and added photos of front and back. I've checked the C6, which appeared to be connected through a hole, but that side od capacitor appears to be a GND.

Nope - it is a PCB. The pad fell off. The only thing that is copper is the little hair trace that's left.

@makerbuddy have you got a multimeter

Yes I do, so I could tell that the trace goes to ground.

Besides I was working on it and today managed to catch the copper trace that was left from the pad. Used some copper wick as a new pad and everything works fine.

Besides that I still did not got idea where it goes! I've checked every component and signal points, but none of them was giving a beep in continuity test with multimeter...
