Introduction

The mouse shipped with OMRON D2FC-F-7N(10M) switches installed. You can find direct replacements for these on many online retailers, but I opted to replace them with OMRON D2FC-F-K(50M) switches instead. You can probably choose a different type of switch if you want, as long as it shares the D2F’s form factor. That’s an exercise left to the reader!

This guide does require soldering, but thankfully it’s all through-hole on some relatively large parts. The hardest part of the job is holding the board steady while soldering the switches’ first contact.

What you need

Step 1

              Remove sliders
  • Turn off the mouse before beginning disassembly.
  • Flip the mouse over so the sensor and power switch are facing you.
  • Insert a plastic spudger between each slider and the plastic mouse base. Pry the adhesive slider off of the base to reveal the screw wells.
  • A careful amount of heat applied directly to the slider before removal can help ensure they are reusable.
  • The mouse sliders will likely be unusable after removing them, they will need to be replaced.

Step 2

              Lift the top off the mouse
  • Remove the five Phillips screws from the bottom of the mouse.
  • Flip the mouse over, holding both the base and the top to avoid it falling apart.
  • Lift the top of the mouse straight up and away from the base. Once it is clear from the screw wells, rotate the top to lay it on its primary button side.
  • A ribbon cable holds these pieces of the mouse together – be careful during this step to avoid damaging it!

Step 4

  • Flip the top of the mouse over to view its interior.

Step 5

              Loosen the grippy facade
  • Flip the top of the mouse over so it is in the orientation it would be during normal use. Turn the top of the mouse so the main buttons and wheel are facing you.
  • Insert a plastic spudger into the seam in the grippy facade at the front of the mouse, nearest the right side of the buttons. It should snap out of place.
  • Apply pressure to the bottom edge of the facade under the middle of the mouse buttons. It should snap further out of place.
  • Flip the top of the mouse over so the main buttons and mouse wheel are facing the work surface.
  • Insert a plastic spudger into the seam between the grippy facade and the plastic base of the mouse at its right side. The facade should almost completely snap out of place.

Step 7

              Remove mouse buttons
  • Turn the top of the mouse so the main buttons and wheel are facing you.
  • Remove the four wide Phillips screws holding the mouse buttons to the top chassis.
  • Insert a plastic spudger between the left side of the left mouse button and the chassis. Gently pry the button to free it. It should pop off, but may require a light push to the right to fully separate.
  • Grab the right mouse button to the left of the mouse wheel. Pull it to the left and away from the chassis.

  • Remove the four Phillips screws holding the mouse wheel assembly to the top chassis.
  • Grab the mouse assembly by the wheel or the plastic and pull it directly away from the chassis.
  • The mouse wheel is able to freely pivot 180º from its plastic assembly. Be careful to hold this assembly together as you turn it to set it down.

Step 15

              Desolder each microswitch
  • Apologies for not having more detailed images… I don’t have a good setup for photography while using both hands.
  • Add some new solder to each of the three terminals on one microswitch.
  • While pulling the microswitch away from the board, heat its three terminals. The switch should come free.
  • If you have trouble with this method, you may have better luck by removing as much solder as possible using solder wick and a solder sucker before pulling the microswitch away. However you do it, all three terminals will need to be warm enough to melt their solder at the same time.
  • Clean the terminals of any excess solder using a solder sucker and solder braid. The holes in the board should be clearly visible, it should be easy to insert your new switches.
  • Double check to make sure each solder pad on the bottom of the circuit board has continuity to the trace surrounding its corresponding hole on the top of the circuit board in case you separated them while extracting the old switch.
  • Repeat these steps for the other microswitch.

Step 16

              Insert and solder new microswitches
  • Insert the switch contacts through the holes in the board.
  • Mind the switch’s orientation! The actuator will go toward the right of the motherboard in this image.
  • Solder one switch contact to the board while pressing the switch into the board. Allow the switch to cool.
  • Ensure the switch is flush with the board, otherwise the mouse buttons will not click correctly.
  • Solder the remaining contacts to the board, allowing the switch to cool each time.

Thanks for this guide !!!

Regarding Logitech quality: it’s a shame that such an expensive mouse (paid 100€ !) has only “normal” micro switches (10M)

I’ve also replaced the switches by a 50M variant (OMRON D2FC-F-7N(50M))

Great work on the guide. My mouse wouldn’t drag reliably anymore, all better now!

I wouldn’t classify this as difficult btw, medium maybe but everything is fairly easy to open.

Just one thing for anyone attempting:

-The first, big ribbon cable to the big mainboard is slide-to-unlock

-All other ribbon cables on the top half are tilt-to-unlock (lever style).

I didn’t look/read carefully and broke the latch on one of them trying to slide it…
