Introduction
I've noticed that I started having issues dragging windows. At first I thought it was a software issue since I recently switched from Windows to Linux OS. But the issue persisted on both OSes so it was clear that it was a hardware problem.
So that is how the saga of trackball mouse disassembling started. The rest is history!!!
This guide will help you to disassemble your very own Logitech M570 and guide you through switch replacement. Note that you will require soldering skills to replace switches. You might get by without soldering skills if you are after replacing the ball sensor.
What you need
-
-
Remove tracking ball
-
Turn power switch to the off position
-
Open battery door
-
Remove AA battery
-
-
-
Remove 3 pads as shown in the picture
-
Unscrew the 5 bolts using Phillips #1 screwdriver
-
The last screw is hidden under the battery label. You will have to poke a hole to get to it.
-
-
-
-
Lift the latch up and pull flex circuit out of connector. Detach tracking ball sensor.
-
Unscrew first screw and detach little PCB
-
Take the other 3 screws out. The last screw is hidden behind a capacitor in the picture

As you may see one of the switches is completely busted. It has to be replaced!
-
There are few replacements out there. I've used this one. But you might want to use original one. Or the rival one.
-
It really does not matter much. The difference is operating force. The original one comes with 75 gf which gives lighter clicking action. But I went with 150 gf for the replacement since those should last longer...
-
Take old switches out. Might be a little tricky! You might want to use multiple soldering irons to heat all 3 pins at once. Or heat gun. The choice is yours. Just be careful not to burn yourself! FYI, this is probably not the best project for the first soldering experience!
-
Solder new switches on.
