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.

Step 5: Locate the click mechanism that is causing the problem (usually left click)

Picture of locate the click mechanism that is causing the problem (usually left click)
Depending on the mouse, there can be one, or several click mechanisms. This particular mouse has 6, with the left and right click being the main mechanism. The left click is the one causing me problems, and is likely the one you are looking for also. Locate this mechanism so we can continue the repair.

Before you proceed, be sure to notice the very tiny white button located on the top cover. This will fall loose when the cover is removed, and you will want to be sure you retain this piece to be reinstalled later.

Step 6: Open the mechanism box

The small rectangular box, contains the part we need access to in order to complete the repair.
To open the cover, use a small flat head screwdriver to gently pry the box cover away from the latch. This will allow the cover to lift slightly until you can do the same to the backside. Be careful not to pry too far or hard as it could damage the cover. The first time I performed this repair, I damaged the cover on mine, but thankfully it still stays in place, so there was no real harm done.

Be sure to retain the small white button to reinstall later.

Step 7: Locate, remove, and retension the spring

Picture of locate, remove, and retension the spring
This is the key to the repair. You must remove the very tiny copper tension spring from inside the click mechanism.

After you have removed this part, make sure the small tab has a decent curve to it. You can see in the picture how I use the screw driver to bend the curve while holding it down with my finger.

Then bend the tab up, so there will be more tension on it after it is reinstalled. You can see the before and after pictures showing how this will look.

Step 8: Reinstall tension spring

This is where the patience comes into play.  This is probably the most tedious and time consuming part of the repair.
To reinstall the tension spring, first attach it to the small hook at the front of the mechanism, as shown in the picture. Then use the flat head screwdriver to push the curved tab into place while keeping the rear of the spring under the small arm at the rear of the mechanism. The second picture shows what it should look like after being reinstalled. Notice the arrows pointing to the spots that need the most attention. You want all three to be correct or the mechanism will not operate properly. 

Step 9: Reassemble the click mechanism and test

Picture of reassemble the click mechanism and test
Next, you will need to reassemble the click mechanism. First reinstall the tiny white button into the mechanism cover (you did remember to find and set aside the tiny button right?).  The easiest way to do this is by dropping or placing it into the cover with a pair of tweezers. With one hand, pick up the cover  while keeping it upside down so the button stays in place. With the other hand, pick up the mouse body, turn it upside down, and push the cover back into place. Doing it this way will insure that the tiny white button stays in place while the mechanism is put back together.

At this point, before reassembling the mouse, set it down on the table, and give the tiny white button a few test clicks. You should notice that it is making a crisp click sound when pressed, and that it now springs back with more force than it did before. If you are not hearing and feeling a difference, you may need to open the mechanism back up and try retentioning the spring again.

If all seems well, than go ahead and put the mouse top back in place, reinstall the 4 main screws, and put the slide pads back in place. If there is not enough adhesive left to keep the slide pads on, you can add some more. Regular elmers glue stick has worked for me, or a dab of superglue would certainly do the trick.

Thanks for reading. I hope you now have a mouse that clicks properly.

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 for the great tip!!! it was kind of difficult to put the very tiny copper tension spring back again on the click mechanism but after that surgical action the mouse works like new. Genius NS6000

Excellent tutorial! It's all close-up and the actual parts were shockingly small :D Reinstalling the spring was a bit tricky, I noticed the tiny ledge in the middle where the spring goes, but I didn't notice there was a tiny ledge in the hook, I was hooking it all wrong...once I figured that out, it was a matter of a few tries. I hope it won't pop out now, the slide pads DO take damage from being removed and put back and the adhesive doesn't adhere like it used to. THANKS for saving my favourite MX Revolution :-)

Works great so far. Lost a screw though, but only took about 10 min.

Yeah when doing this please put your finger over the white button! Unfortunately in my case it was red, and when I was trying to release the small black box, it flew away with the red button (on a carpet and dark wooden floors, at night). It took about 2 minutes for me to find the black box, but after almost 10 minutes looking for the small button I gave up. After a few seconds looking at the mouse, I figured I'd use the button from the scroll wheel click, which I don't really use at all. This time, I put my finger over the box and got it off without either of them flying away. But, when I went to put the red button in the other black box, it accidentally fell too. So this time I searched for about 15 minutes and gave up again. Thank god it's a laptop. I guess tomorrow I'll sweep the floor and hopefully it'll show up!

Did this operation in about 10 minutes on my logitech g500 gaming mouse. I am an IT Expert though.

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 http://sh.st/lDXry 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.

my old mouse had this problem, really had fun doing it.
step 8 took some time but i think the next time i do it it'll only take me a few minutes :)

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. (:
