Introduction

One of the main culprits of the scroll wheel button not working may be due to accumulation of dust, which can be solved with the use of WD40 — or even better if accessible: Permatex dielectric grease.

If the switch needs to be fully replaced, steps 8 and 9 will consist of soldering and desoldering of the tactile switch on a PCB (Printed Circuit Board). The switch size of this particular mouse is measured 6.00 mm by 6.00 mm with a depth of 5.00 mm vertical (with two pins).

Before tearing down the mouse, double-check the scroll wheel button by connecting your mouse to other devices, running your hardware troubleshooter, and by updating the mouse drivers. Once identifying it’s not a software issue, you may proceed to fix the button physically after disconnecting the mouse from any ports.

What you need

Step 1

              Tactile Switch (Scroll Wheel)

Flip your mouse over so the bottom is facing upwards.
Make sure the mouse is disconnected from any ports before tearing it down.

Step 2

Pry in between the aluminum and plastic parts of the lower part of the mouse chassis using a spudger.
Work around the left and right click areas with the spudger to further loosen and remove the mouse shell.
You may need to use extra force to displace chassis slots from the mouse shell.

Step 3

Pry in between the aluminum and plastic parts of the upper section of the second mouse chassis using a spudger.
Carefully make your way around the chassis with the spudger.
A little force may be needed at the bottom as the chassis is being supported through plastic pillars underneath.
Potential for device damage. Do not pull the chassis from the mouse; these parts are connected by sensitive ribbon cables.

Step 4

Remove the three 2 mm screws attached to the PCB using a Phillips screwdriver.

Carefully wiggle and pull the white plastic ribbon cable attached to the PCB.
Now you can work on the half that has all the components.

Step 7

Spray WD-40/Permatex dielectric grease on the switch/button to lubricate and remove oxidation.
Press the tactile switch multiple times after spraying.

Step 8

If your tactile switch is not being replaced, Steps 8 and 9 are optional.
Desolder the faulty tactile switch.
For soldering help, check out the guide on soldering/desoldering connections.
Remove the faulty switch when loosened.
Caution: Hazardous situation which, if not avoided, could result in minor or moderate injury. Eye protection (safety glasses, goggles, face shields, etc.) must be worn when soldering. Usage of a soldering clamp is highly recommended as soldering irons can reach temperatures of 200°- 480°C.

Step 9

Solder the new tactile switch.
Make sure to heat the solder on to the copper.
Clean the solder tip with a brass sponge/normal sponge if necessary.
When you’re finished, make sure to turn off the iron and allow it to cool off on a soldering iron stand.

do not spray WD40 on electronic switches… clean them with alcohol

Please do not follow step 3 or you’ll break the cover. You don’t have to pry that plastic cover off. Just undo the two screws at the bottom and it easily comes off.

Also, if your left click feels mushy or has a lot of pre-travel where you can’t spam your clicks, just tighten those two screws at the bottom and that should solve those issues.

I can confirm that opening the mouse , cleaning up the omron micro switch(I am pretty confident those are high quality switch) , lubricating the micro switch , reclosing the mouse and tighten the srews fixed it for me. Theres no problem spraying a small amout of wd on a micro switch in the end its a mechanical micro device. Also do not follow step 1 and 2 . Simply unscrew the two philips screw under the mouse and it open very easely
