Logitech G102 Lightsync: Teardown & Fixing Double Click Issue
This is Logitech G102 Lightsync Mouse that developed the common double click issue. My original unit didn't have it but that developed the scroll wheel issue so RMA-ed it under warranty and then this replacement unit developed this double click issue after warranty expired. Today we will be repairing the same.

Hey Everyone! This video is about how to fix double click issue on G102 LightSync Mouse.
Now some may say that G102 LightSync is an improved version of G102 Prodigy and doesn't suffer from that problem but that is not the case, not for me at least. I'll briefly explain what this double click issue is, it is when you hit the left Mouse button once but your operating system registers it as a double click it can be very frustrating if you work with professional applications like Photoshop or Premiere Pro on your computer. So, we start by taking off the two mouse feets to unscrew two screws and then puncturing the sticker below the sensor to reveal the third screw. After opening up the body you'll find that the main left and right click buttons are Omron Switches and the rest of the three switches that is scroll, back and forward buttons are Kailh Switches. What came to me as surprise was that this mouse is using a mechanical encoder from Kailh for the scroll wheel. These mechanical encoders are more prone to failure as compared to the optical encoders in my opinion. I have already RMA-ed this mouse once when the
Scroll Wheel was not working properly (Skipping more lines then scrolled). Then after warranty expired this Replacement Mouse developed this double click issue and that's where we are today. So, let's continue further. Be very careful when you are opening the black plastic housing for the switch. Open it equally(evenly) from both front and back side so that you don't bend the fragile metal clip which is inside this housing. After you remove the housing, you will need to take out that metal clip out of the switch terminals. I can't stress enough on this - BE VERY CAREFUL while removing it as well as when putting it back together. Do it like I'm showing you here. If this breaks you are done and you will have to find or order this switch D2FC-F-7N(10M) somewhere online. Then you'll also have to do some soldering work or you will just have to buy a new mouse straight head. So,
this issue develops because of the carbon deposits on the switch terminals. That happens naturally as you are using your mouse every day so to clean it off just use some isopropyl alcohol or glass cleaner liquid with maybe an old toothbrush which has some soft bristles you know and just rub it off all that gunk from there and yeah and you are done. Now you just need to put this metal clip back together and I'll repeat just BE VERY CAREFUL and do exactly what I'm trying to show you here and we'll close everything
DO NOT TRY TO BEND THE METAL CLIP'S CURVED PORTION. TRUST ME IT'S NOT WORTH IT, I HAVE RUINED AN OLD LOGITECH MOUSE WHILE DOING THAT.
and lastly I will be using this particular website (Link in description)
to test if my issue is finally resolved or not.
So, as you can see that I clicked 30 times and this website registered 30 clicks only, no more than that. So, our repair was successful.
