Introduction: 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

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

Remove the four screws with a small philips head screw driver.

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)

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

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

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.

Thanks, this helped me a lot. It was frustrating trying to put the spring back in and eventually it broke. I switched it out with my scroll-button spring, since I don't use it.

When putting back the spring, it has to be just right. The hooks, at both the end and the springy part in the middle, both need to be hooked right at the top of the post, as close as you can get it without it slipping off. The first time I did it, I had the spring too low. It would seem to click with the white button, but the mouse button, after assembling, would have to be pressed very hard in order to get it to click. The only way I figured this out was by disassembling the black box of the right mouse button, and using my smartphone camera's zoom feature to magnify the side view of the spring to see where it sat, exactly.

One tip in this guide that wasn't mentioned in Youtube videos is how to put the spring back in. After struggling for over an hour to get it back in, I finally found this guide which helped me get it back in immediately.

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!

Thank you for the great tutorial. Saved my mouse. And thank you for taking the time to share it with us.

Took me two hours to put the spring back in, but it works now! Thnaks :)

So I just attempted this on a Logitech MX280, which has an Omron switch. This instructable is quite dangerous in that it assumes that all the switches has similar construction on the inside. For the MX280, instead of pulling out the metal (which I did, and regretted), you can fix it in place as shown.

When bending metal you can never get it back to it's manufactured state and like the author says eventually the part will break. This seems to be a suitable replacement part (with a little soldering). Plastic housings do break etc so maybe this will save someone's mouse out there. My ripjaws MX780 has been double clicking so I was doing some googling and came across this - I prefer to solder a new button because this mouse is a bit of a pain to disassemble.

I'll dig through my mouser and Burklin catalogs to see if they also source these parts (I'm sure they do) and update as needed for other vendors.

Brilliant. Now all we need is someone who's fixed this button in a LAPTOP!

Thanks a lot! I was able to repair my performance MX mouse, the left click is now a bit hard but it's better than the double click disaster!

Wow, that was tense. After 30+ mins of trying and failing to get the spring back in, and trying not to panic that I had destroyed everything, I read through the comments, found @AlexandreP11 's brilliant diagram, and got the spring back on. But it seems I had weakened the spring with all the fiddling, and the click was worse than ever. Boldened by the small triumph, I took apart the right-click spring and swapped them over. Bingo! Left-click fixed and actually the right-click spring seems happier on the other side of the tracks. Thank you so much.

I have a Trackball mouse and it seems like everybody else has a regular mouse, I hope this procedure won't be much more difficult (assuming that trackball mice have more components stuffed and crammed into them tightly)

Thank you so much, my mouse is like new !

It's just hard to replace the tension spring but I place the small center curved tab first and the hook in a second time, easier for me.

I successfuly fixed double clicking in my Razer Orochi 2013 following this tutorial, but I recommend the alternative way of putting the tension spring back into place (I used the great visualization by @AlexandreP11), which resulted in a 10 minute effort after fiddling and yelling at the copper piece for 40 minutes.

Earlier
comments that this won't work if the microswitch is too far gone are correct -
I tried this on a Microsoft Intellimouse Explorer 3.0 which has been iffy for
some time and the sprung contact was very flimsy. I took the sprung part out of
another microswitch (they're all the same Omron switches) on another mouse but
it seems the centre post on my mouse's switch was worn too so it wouldn't
locate.

In
the end I borrowed a soldering iron, took a switch off the other mouse and used
it to replace the one on the Intellimouse. Success! Thanks for inspiring me to
do this! Incidentally, I noticed Microsoft just relaunched this mouse!

I have to say that I'm
filled with admiration for people who have pulled this off - once I'd finished
for fun I tried to re-assemble the switch I'd taken the spring out of and it
ain't easy!

I freaked out a little bit about how tiny the mechanism is and I was afraid I wouldn't be able to see the parts and or how where they are supposed to fit but in the end it proved much simpler thank I anticipated! My mouse is now clicking as good as new! Thank you!

Thanks a lot for detailed procedure, it worked quite well.

Though putting the spring back was not an easy task, but method described by @AlexandreP11 made it so easy.

W"hat if I have a mouse that single clicks when I click fast? like sometimes in games I click between 2 and 5 times for something but the mouse only registers one continuous click.

It might be related to spring getting stuck and not returning fast enough (even with the click sound)

I'm not familiar with that issue but if this guide helps you resolve it, please let us know.

It did solve the problem in less than a minute unlike before that I always replace the clicker and unsoldering is such a pain, however on my end it sacrifice the clicking feel and sound, does it really goes that way after repair or I did something wrong?

If your budget allows it, it's a better idea to keep a bag of good quality switches in your drawer and replace them when it no longer clicks like it did before.

Omron switches nowadays are pretty cheap -- though, you might want to look carefully so you don't get recycled ones. Else, Kailh makes decent switches too.

Just a tip! This tutorial will work best when the problem with the button isn't serious.
