Step 12

              Removing Mouse Wheel
  • Disconnect the mouse wheel sensor cable from the main board
  • Insert the flat end of a plastic spudger underneath the rear clip of the mouse wheel
  • Using the spudger as a lever, push up on the rear clip to release it from the assembly
  • Be careful as the mouse wheel could go flying when the clip releases

Step 13

              Removing Top Board
  • Remove the black round head Phillips screw holding the top board
  • Lift the top board straight off of the bottom board
  • The top board connects to the bottom board via a pin connector. Use caution to avoid bending the pins when removing and reassembling

Step 14

              Replacement Micro Switches
  • There are a number of replacement mouse micro switches available for replacing a faulty one. The quality control on these is not the greatest so buying in at least pairs is advisable
  • The original micro switch is an Omron D2FC-F-K(50M), the 50M referring to its lifetime click expectancy
  • The replacement switches here are from a Lenovo mouse that was bundled in with a new computer. These switches are the right-click (black) and middle-click (black/white)
  • Micro switches donated from another mouse ideally should have little to no use on them, otherwise you might be doing this repair again

Step 15

              Removing Faulty Microswitch
  • Apply flux to where the faulty micro switch is soldered to the board
  • Using a solder sucker pump in conjunction with your soldering iron, heat up the solder and then use the sucker to remove the molten solder
  • Don’t be afraid to put the solder sucker tip right up next to the soldering iron; it will only need to be in contact for a brief moment when you press the release button
  • Remove the faulty micro switch once desoldered. You may need to heat up the pads while doing so
  • Use a pair of tweezers to avoid getting burned if removing while applying the soldering iron

Step 16

              Soldering on New Micro Switch
  • Fit the new micro switch in place, noting the proper orientation
  • Heat up one pad at a time with your soldering iron, adding fresh solder to the pin and pad
  • Be sure that the micro switch stays in place when soldering
  • Once the solder has cooled, clean the flux residue off with isopropyl alcohol

Excellent guide! Was super easy to follow.

My left button works again (although I took the switch from a Logitech MX1100 that had the exact same Omron switch and the same fault with the other switch in that mouse).

Solid guide thanks. I also replaced the right click since I had it open, that is on the main board so only recommended for the confident, it’s fiddley but not any harder.

  1. Replace the magnetic side on the mouse. This will hold the inside magnets in place in later steps

  2. Unplug battery! Pull the connector, not the wires

  3. Unplug the ribbon, the black part is a tiny lift-up latch to unlock the cable, gently pull

  4. Remove all screws holding the plastic inner frame & battery (battery can stay glued to that)

4a. Note there’s a tiny wedge light-pipe by the magnets that’s now loose. remember to put that back

  1. Gently unstick 2 silver tapes connecting the thumb circuit board to main. You need to put those back to reassemble

  2. Remove screws in main board. Gently lift out sidewise and up.

6a. Note the bottom on/off & 2.5/BLE switches may or may not stay in place.

Reassembly == reverse steps. Take your time lining up the pieces slotting the mainboard back in.

Tip: Cut the microswitch apart if de-soldering is being a pain

I’m having issues with my forward side button, do you happen to know what type of switchs they are and how can I replace them?

Michael Fiorenza - Jan 17, 2023

I’m experiencing the same issue with my side button, and Corsair support told me I was out of luck. I’d like to know what the side switches are as well so I can do a full refurb on mine.
