Step 1
Opening the case
- Some earlier variants of the Anywhere Mouse have a matte finish on the buttons. It is unknown if the internal construction differs from this later, shiny button version.

Step 14
Removing the scroll wheel
- With the power switch board unscrewed, you should now be able to flip the main board upwards.
- Unscrew the two screws indicated in red.
- The retaining bridge should now easily come off.

Step 15
Removing the scroll wheel
- Remove the screw circled in red.
- The scroll wheel assembly can now be lifted upwards and removed from the mouse.
- The black plastic piece where the screw removed in this step is located is spring loaded and can fall out of the scroll wheel assembly. Be sure not to lose this piece.

Step 16
Removing the scroll wheel
- If the black plastic piece has fallen out of the scroll wheel assembly, it should be oriented like this when reassembled.
- The plastic piece has a small peg that inserts into a spring-loaded hole in the scroll wheel assembly.

Step 18
Darkfield sensor and lens
- Remove the four screws circled in red. The sensor assembly can then be easily removed by pulling it up and out of the casing.
- Now you can clean the lens of the mouse. The sensor itself is permanently attached to the lens however.
- This particular sensor integrates the infrared laser diodes in the same package. It is rated at a sensitivity of 1000 DPI.

Step 19
Conclusion
- The mouse is now fully disassembled. The main circuit board was not removed from the casing as it was not necessary to access the sensor and remove all other parts of the mouse.
- The major parts of the mouse are visible in the first two images of this step.
- Here is a shot of the bottom of the main circuit board. The power switch circuit board is indicated in red while the mouse’s microprocessor is indicated in blue.

Where can you order new switches when I want to replace them?

An electronics parts supply website like Mouser should have them. I don’t know what specific switch you would need to replace the ones on this mouse. They are smaller than the usual microswitch. You would also need to desolder the existing switches to remove them and then solder the new ones back on to replace.
I just saw this from the other guide on how to replace the mouse switches:
“I have found 3 different manufacturers which sell micro switch replacement part for Logitech Anywhere. I only have tried E-Switch.
E-Switch TS20100F070S (Digi-Key | Mouser Electronic)
Omron D2LS (eBay | Digi-Key | Mouser Electronic)
Kailh MI873101S01 (eBay)
ZIPPY DA T Type (Original micro switch)”

Thanks for the guide. I was cleaning my mouse and the plastic switch from step 13 dropped out and I didn’t know where it went! :)

Thank you for that guide. I completed until step 5 then directly step 15 and i can remove scroll wheel without unscrew anything else except screw for buttons pieces.
It was enough to clean around scroll wheel and right and left button.
Now, it works well and scroll wheel turns freely.
So, thank you much.
That afternoon, we ask us if we must buy another one…
