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 buy without soldering skills if you are after replacing the ball sensor.

Carefully remove PCB. Take care not to bend battery connector Remove power switch. Otherwise it might fall out and you will never see it again...

Ass 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 is 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.
