I have repaired it – without soldering, replacing switches or without cleaning the switches. I have got this Mouse for repair from the friend having shop beside my workshop indicating the symptom none of the switches are working after fall down the mouse.

I opened the mouse for repair and I found some plastic part dropped down on the table. So I have stared visual inspection from where this part is belonging to.

I have checked the PCB but everything found intact so when I removed the PCB From the mouse I realize that this broken part is PCB Supports.

I found that from the mouse top cover while clicking- the pointing lever is not reaching up to the switch because this PCB is little fall downside hence it is not clicking.

Pointing Lever should press the RED top on the switch.

So for this type of repair you have to think out of the box and develop you’re another skills they may be related mechanical / plastic / chemical / adhesive and many more.

I have stuck the plastic with quick fix liquid (cyanoacrylate).You have to be very precise for this type of work because if support is not in the line of PCB hole then your PBC will not fix properly on his place.

And fixed the PCB

After this fix I have reassembled the mouse and tested on my computer it working fine.
