Picture of Repair mouse with double click problem

I have a Logitech wireless laser mouse and after a year or so of use, the left click button would double click every time I tried to single click something. As can be imagined, this gets frustrating very fast. So, being the tinkerer that I am, I decided to open her up and see if it could be repaired. Sure enough, It's a pretty simple fix, if you have some common tools and a teaspoon (edit:a tablespoon) of patience. There are some very small parts involved, so you will want to make sure you ware working in a well lit, clean environment so that any parts that are dropped can be easily found. I have now performed this fix for the third time and decided to take pictures this time to share with others who may find this useful. Each time the repair lasts about 6 months to a year before needing to be redone. I imagine at some point the piece causing the problem will break, at which time the mouse will need to be replaced (unless you're determined enough to try and source parts). Good luck with your repair, I hope this helps.

EDIT: There are quite a few comments about the difficulty of step 8. I would advise that you read through some of the comments for various approaches to completing that part of the repair.

Step 1: Remove batteries

If you are working on a wireless mouse, you will want to first open the battery cover, and remove the batteries from the mouse.

Step 2: Access screws

Picture of access screws
On this particular model there are four screws which hold the mouse body together. These screws are located underneath the slide pads on the underside of the mouse. To remove the slide pads, gently pry the edge of the pad up with a small flat head screwdriver and peel it off. They are held in place with some sort of adhesive.

Step 3: Remove screws

Step 4: Open her up

At this point the top cover should lift off, revealing the mouse's innards.

Thank you very much. It took me around 15 mins to complete the fix (on a second attempt).

you just need to increase the strength of the curved part (the spring),
so you can use a steel rule or whatever to slightly flatten the curved
spring, then put it back on the contacts.

After you flattened the spring, it will be harder for you to put it back on the tiny switch.
I don't have tweezers with me, I used a pair of nose pliers to put the spring back in place. My mouse is like new again.

I cant believe it worked. After some yelling and time I finally got the damn copper piece into place. THANKS!

Hi, thank you very much for the great tutorial - I've tried it and my mouse is working fine. May I suggest that for step 8: Reinstall tension spring, you (1) place the curved tab (which is in the middle of the spring) at an angle on the tiny ledge of the metal piece on the mechanism first, then (2) hook the spring onto the front part of the mechanism, before finally (3) sliding the spring beneath the rear part of the mechanism?

I did not have much luck with the original action series of 2-1-3 until I tried 1-2-3 and the whole spring just slid into place while pivoting on the middle curved tab.

Hope this helps. And once again, thank you!

Thanks to you I saved ~$60 towards a new gaming mouse. The only difference is that mine had a groove instead of a hook. I had to slot the back bent piece in first and then the front. Also if someone does this again then do it in the middle of a big table. You'd be surprised how far the tiny pieces (especially the small bit of plastic on the switch) can fly and bounce even on carpet.

It is a great article for me. I repair monitor,smps, mouse,tv etc but i never repaired this switch, i just replaced it. Now i can repair the switch also. I repaired my mouse switch and it is working like a new mouse. Thanks for the tip.

I need one more help, in usb mouse, it is not detected ( no new hardware found message). Mouse cable is ok, i checked each wire individually, led is lighting but not detecting, Is it a chip problem or something else. Thanks in advance

It's helpful but I just use this instead after running it, my mouse doesn't double click anymore. But thanks for this, I'll do this and if it's still double clicks I'd just use the tool

Thank you very much. Now I can use my gaming mouse back!

But putting the small copper back to it's place really needs some patience.

That's a G700? Were you able to reuse the teflon pads? They really look like they will end up destroyed if I remove them.. :-/

Thank you very much for this! My GX DeathTaker was saved. Tried countless times without managing to get the clicker to work until I decided to dissasemble the other one to see the exact shape of the spring and that was it.

When my Cyborg M.M.O 7 started doing this. I found a sorce of the switches, very cheap. I think it was $2 for two. Instead of replacing the whole switch again I'm going to try this. If anyone want's that link for some of the switches let me know I'll find it. ¤I love this website¤ This is my new favorate site. Keep tinkering

Many thanks. I had to disassemble it and reassemble it again to make sure I understood it. Tricky but perseverance does it.

Thank you very much for these instructions! Following them helped sort an annoying double clicking issue on a generic wireless mouse from eBay - not a lot of money saved but worth it for the satisfaction of fixing it myself. :-) For this mouse reattaching the spring was not too bad as it was possible to completely remove the electronics from the case, making it easier to work on.

Sounds great. I have the same problem. I will apply the procedure and share the results.

Thanks in advance.

Thanks for this tutorial, fixed my double clicking mouse! I broke one of the springs on the first attempt after forcing it out. The trick is to swivel it to the side about the hooked point until it dislodges. Do not just yank it up like I did. After a bit of practise, I could open any of the microswitches with ease. A penknife to lift the plastic cover and tweezers to align the spring can help a lot with this tiny job. This saved me money and extended the life of my mouse.

I also bought a couple microswitches from ebay to replace in future.

Holy hell trying to get that spring back into place with only your fingers is probably the worst mechanical thing I've ever had to fix, and I've fixed/dismantled cars! I tried all the tips I could find but in the end I just shoved the one end under the arm, made sure the spring was in it's little nook, then just pressed down on the front hook until it snapped into it's position, probably not recommended, but I had about given up.

When it clicked into place and didn't go pinging off into space I could tell right away that it was solid and in it's correct position. A quick test with the on-screen keyboard after reassembling the rest confirmed the fix worked, but hell if I'll ever bother spending 2 hours trying to maneuver a microscopic piece of metal into a tiny notch again.

Thanks for the instructions tho!

The little metal prick took me four hours to install back in its place. My back hurts like hell. Thanks a lot for the guide!


That's an awesome kit. where did you get that holder with magnifying glass thing?

Oh, and mine's got a LED and a soldering iron holder (they can't be seen on that picture I posted). It's so nice. (:

It's just now that I see your post. They're called "helping hands". They're cheap ($10-20 / £7-13). You can either get them from a local electronics shop or from eBay. (: Very useful clankers. (:

I managed to mess it up on the first try and I ruined the spring, but luckily though I had a broken spare mouse from which I "borrowed" a new spring, here is a tip for anyone who tries to make this repair.
The amount of tension needed to put the spring back in its place is VERY small, I found that this trick made it on the first try, good luck.

Thank you so much :) Very much appreciate your tutorial / instructable. Helped to repair my Logitech wired mouse :)

Actually you don't have to pry off the slide pads. Just use a thin screw driver to make a hole on the pads and unscrew the screws just enough so that you can open up the mouse.

Thanks for the tutorial. For the step 8 I put the front end of the spring on the hook and while holding it, put the rear end in between the hooks and finally put the middle part sliding it from the side.

Hell yea! finally got my mouse working!!!!!

The copper piece was not a big deal, just put the curved edge in its place first then do the lock thing.

the hardest part was the small white part as I didnt had right thing (did it with hands , I dare u to do it with hands in less then 30 mins!)

Hi there

I did it in just 4 minute.

1 I opened the mouse Genius

2 Looked for the microswitch

3 cleaned the microswitch with spray electronics cleaner 3 times clicking the microswitch

4 closed the mouse

5 whoa! is working again pretty fine

it worked for me as well. no need for "cleaner" actually, just blow air strongly with mouth , that's it
