Intro: 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.

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!

If you need help repairing your mouse and don't want to mess with insides of the actual button switch, you can replace it instead! If you need any help with that I just made a video on the process:

Don't go all out and remove the copper spring. For most issues with mouse buttons, just take the cap off the micro switch and carefully clean the copper contacts inside with a small brush and alcohol (96% isopropyl alcohol). Chances are it will fix "bad" clicks and you won't need to remove the copper part.

:/ <-- The face you're making when you spend 2hrs on a switch using this method, and then you realize you just did the WRONG switch, the one for the middle-button from the wheel...

.

Anyway, here is my takeaway on this method:

.

* If you take out the copper spring, you will hate the world, yourself and everything else. I figured it out now, but anyway...

.

* I suggest NOT taking out the copper spring, but instead just take the cap off from the switch, and with a small brush like I did clean the parts with alcohol instead. I think that in a majority of cases, the problem is not a lack of "spring power" so you'd have to re-shape the spring, but oxidation on the parts. (I noticed the oxidation on several mice who had problems with the buttons). Sometimes it can also be dust/hair preventing proper contact. Sometimes, I noticed the copper part is not centered right, eg. with Chinese no-name switches.

This is my experience. I fixed mice now WITHOUT having to take the copper part out. (I used 96% alcohol like you can get in any drug store).

.

-> soak the brush with alcohol and clean the parts inside instead. At the location of the small plastic switch, push down so the contact opens and also brush in between, or use a paper towel that you soaked with alcohol and clan between the contacts. I wouldn't recommend a Q-Tip since they "shed" hair, but you can try.

.

Wait a minute until the alcohol has evaporated, maybe with a lens check whether there's any hair etc. left, put the cap down again. (Thanks for the tip fixing the white switch with clear tape when you do this).

.

Again: I do not believe you need to take out the spring! Likewise, the copper is so soft that any bending you do will likely not last long anyway, and just the re-assembling of the part, in my experience, bends everything back as it was before. You will end up like before, maybe even worse.

I attempted this repair but did not have tweezers. I gave up and just salvaged the button from another mouse I didn't use anymore.

I'm trying this on a 2013 Razer DeathAdder, the srpings are absolutely horrid to put back in place, it's like there's an almost invisible groove you have to put the spring in from which it will constantly go out at the slightest breeze (have to to it twice because I wasn't sure about where the spring actually rests, managed to put the right click back together at least).

Here's a little trick for putting the button back together, it will save you a LOT of nerves:
put some clear tape on top of the cover, put the button back in and press it all the way out against the clear tape. Voilà, now you can put the cover back on the mouse without having the hold it upside down.

Lovely! This saved me a ton of trouble and tremendous cussing on the mouse for not working right.

I used this on a different mouse and it worked. Only thing is that there were five screws and one was under a label. Sneaky.

I have the same mouse as the one in this article but for me the issue was not the double click, it was the right click that was not working half of the time, and it was getting worse. I followed this tutorial to disassemble the mouse and just after the step 7 I noticed some greenish rust on the contact part of the tension spring (that circle on the opposite side of the small hook). I removed the rust with a screwdriver, followed the rest of the steps and the right click works perfectly now.

Thank you, great tutorial! Step 8 indeed the hardest one, it took me more than one hour to reassemble the tiny and flimsy click mechanism. Now my msi Ds100 works normal. Also thanks to csheng1 for the tip, helped me on step 8.

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.

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.
