Introduction

It's an easy procedure to fix the problem. You can watch the mouse being disassembled for more help.

Take the mouse shell apart, held by 4 screws
Unsolder and replace the micro switch

I have found 3 different manufacturers which sell micro switch replacement part for Logitech Anywhere. I only have tried E-Switch.

Desolder the micro switch and replace it with a new one, E-Switch TS20100F070S. Some have trouble to desolder the switch. You can eventually clip the tab to remove the switch. Once the switch is remove you can easily remove the solder tab.
I use a Weller ST7 0.03" X0.79 mm ST Series Conical Tip to remove and solder the micro switch
Just remember, the micro switch doesn't have a polarity. But the connectors will guide you which side the micro switch needs to face.
