Introduction

This guide will show you how to replace the micro switches for the left and right mouse buttons of your Logitech G603 gaming mouse to resolve double-clicking issues.

This repair requires soldering so for those who are not experienced it may be a difficult repair. Please refer to the How to Solder and Desolder Connections for more information on soldering.

Tools

Step 1

Flip the mouse onto its back.
Peel back the pads on the top and bottom of the mouse to reveal the four screws.

Step 2

Remove the four screws with a small Philips screwdriver and set them aside.
Remove the battery plate and batteries.

Step 3

Start at the same location as the previous step, and use your thumb to carefully pry the base from the shell of the mouse.

Step 4

Now that we have displaced the lower half we need to move to the front of the mouse.
There will be two crevices that are attaching the base to the shell of the mouse.
Using a spudger, gently and carefully pry along the dotted red line marked in the first photo until the shell and the base are separated.
As soon as the base and shell are separated, be careful not to pull them apart as they are still connected via a power and ribbon cable.

Step 5

Use this photo as a reference of what is to be expected when opening the mouse.
There will be two cables that need to be disconnected before completely separating the shell from the base.
In this photo, the left is the ribbon cable for inputs, and the right is the power cable.

Step 6

To remove the ribbon cable, use your thumb and index finger to pinch the latch upwards.
Once the latch has been released, pull the cable out of its slot.

Step 7

To remove the power cable, slowly and carefully wiggle the cable out of its socket either with your fingers, a spudger, or a flat head screwdriver.
Take your time with this process as the connection is a tight fit and might accidentally remove the socket with the cable.

Step 8

Use this photo as a reference of what the inside of the shell looks like once the power and ribbon cable have been displaced.
Here, you will be able to see the underside location of the switches that need to be replaced.
Here, you can see the location of the next step which will be to unfasten the side button circuit board.

Step 9

Because the mouse switch circuit board is connected to the side button circuit board, we will need to remove the screw guard that keeps it fastened to the mouse.
Locate the screw marked in the first photo. Remove it by using a Philips head screw driver and twisting in a counter-clockwise motion.
Make sure not to lose the guard underneath the head of the screw as it keeps the circuit board from falling out of place.

Step 10

The switch will be hidden under a cover to prevent debris from entering the device or being displaced. This step will remove that cover.
The cover will be secured by a latch and a screw.
Use a screwdriver to remove the screw by twisting in a counter-clockwise motion.
Using a flat head screwdriver, push the latch upwards and into hole from which it protrudes until the cover loosens.
Do not forget to separate and categorize your screws for when the mouse is being put together.

Step 11

Using your index finger and thumb carefully displace the cover to reveal the switch.

Step 12

The switch board will be secured by two screws. Using a Philips head screwdriver, remove the two screws using a counter-clockwise motion.

Step 13

Using a spudger or a flat head screwdriver lift the circuit board from its slot.

Step 14

To reiterate, the mouse switch board is held down by the side button circuit board. Now that we have unfastened the side board, use tweezers to dislodge it out of its slot.
Once there is enough room, pinch the board loose with your index finger and thumb

Step 15

With the side board in hand, twist the board until there is enough room for the switch board to exit the gap located in the last photo.

Step 16

Now that we have the first switch displaced, repeat steps 11-14 to displace the other.
Proceed to step 16 to remove the mouse switch from its hole

Step 17

Now that the switches have been displaced, prepare your soldering equipment for the final steps.
The setup in the photo contains the minimum of an exhaust vent, a solder sponge, a soldering iron, a solder, and flux.

Step 18

Remove solder from the pin joints to displace the switch by using solder pump.
Flux can be used to evenly distribute the heat from the soldering iron to the solder joins.
Use 91% Isopropyl alcohol or above to remove residual flux.

Step 19

Once the residual soldering flux has been clean, begin soldering in the new switch into the board. Repeat steps 19 and 20 for the other switch.
Clean all residual flux.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Excellent guide! Thank you for putting this together. I replaced my switches following my mouse double clicking on the left button about 5% of the time. The switches I ordered didn't have the right terminals (they were flat and short with holes in them). I had to truncate them a little to make them fit into the holes in the PCB. I also replaced both left and right buttons since the switches I ordered had a minimum order quantity of 5.
Perhaps indicate part number for the switches that are the correct type in the guide? I ordered the Omron model D2F-01F-D. They work great except for having the wrong terminals. You probably want to order the model D2F-01.

What an awesome guide. The pictures and detailed descriptions made it possible for me to follow even though I never do these things normally. I just thought I'd give it a try since it would save me so much money - and it did! :) Thanks man, you're a gem.

I got the replacement clicker called 2FC-F-7N (costs basically nothing) and it fits and works perfectly after installation.

I only know the basics of soldering, and haven't soldered anything for 15 years, but was able to change the component successfully, so it seems like it is somewhat forgiving even if you don't handle it perfectly.

Thanks for the Guide! managed to replace the switches on my mouse with kailh gm 8.0 after it had been getting on my nerves with false double clicks for a long long long time... (did this even without desoldering pump or wick, prying below the switches and heating up the solder spots one after the other dislodged the old switches bit by bit)
