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.


<p>Thank you very much. It took me around 15 mins to complete the fix (on a second attempt).</p><p>Actually <br> you just need to increase the strength of the curved part (the spring), <br> so you can use a steel rule or whatever to slightly flatten the curved <br>spring, then put it back on the contacts.</p><p>After you flattened the spring, it will be harder for you to put it back on the tiny switch.<br>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.</p>
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? <br> <br>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. <br> <br>Hope this helps. And once again, thank you!
<p>I have done it and everything is working well now. Thanks a lot!</p>
<p>Awesome!! Great stuff. Save a me a tiny sum to go get another mouse. Thanks a lot.</p>
<p>Oh wow, thanks for the instructions. I tried to not yelling at midnight while installing the damn spring lol.</p><p>My mouse is Toshiba U20. The curved part of original spring was snapped at first attempt to repair it (before I found your instruction. Basically it was a blind repair lol). </p><p>After I read your instruction, I remember that I have another broken mouse, so I decided to repair it again... and it works! It was hard to install the spring especially if there is a very little space available (the pic is not mine, but it's the same Toshiba U20)</p>
<p>Fantastic guide!</p><p>Unfortunately, to my dismay, my mouse does not come apart easily. </p><p>I have written a piece of software that seems to help (http://github.io/cemrajc/clickfix/releases/lastest) - it just debounces mouse clicks (left, middle or right clicks). It works for my mouse and hopefully it's useful for someone else too :)<br> </p>
<p>Note that the correct URL is (as of 2016) <a href="https://clickfix.cf" rel="nofollow">https://clickfix.cf</a></p>
<p>Brilliant piece of software, thanks alot!</p><p>Now I only need a Mac OS(X) version for my office macbook..</p>
<p>Old Logitech Mouse (10 year old!) repaired in 30'. Thank you!</p>
<p>The double click was bugging me big te and this fix did it! </p><p>Step 8 to many many tries though. I finally got that piece in place by holding the left end steady with my thumb and adjusting the piece with a set of pincers. </p><p>A THOUSAND TIMES THANKS! </p>
<p>Why does view all steps not work? it just refreshes the page</p>
<p>I did the same on my 4 year old Performance MX and it worked.</p><p>Actually 2 years ago I had the same issue and I fixed it by adding a thin layer of adhesive tape between the plastic button and the micro-switch.</p>
<p>Thanks for great manual. 5 years old mice received 2nd life. In step 6 instead of flat head screwdriver I found very convenient to use pin or needle to leverage the front part of black box with white tiny button.</p>
<p>Awesome! Works.<br>I did however first place the spring part under the ledge first, then made sure the spring was in place, and then retracted it to the front.</p>
<p>Thank you for the most excellent instruction!!! I have the exact same mouse that has recently encountered the exact same problem. Normally I wouldn't bother and just toss the mouse since it's served me well for years already, but I figured I could spend 15 minutes on it. It took me more like 30 because of that dang Step 8. You instruction was about as good as possible, but there still is a certain knack to reassembling those tiny pieces that you have to learn. Hopefully, I will remember the next time it happens. </p><p>I took the opportunity to clear out all the dust balls as well. Now the mouse works like new. Thanks again.</p>
<p>Saved my G602! Only took about an hour, tweezers were really useful. Ordered some Omrons just in case even though this seems to have fixed it. Man double clicks can really destroy your sanity...</p>
<p>Took me 3 hours on step 8, finally bent the tension spring in tension and threw the mouse away...</p>
<p>ya dont try this at home... only try this at home if you want suicidal thoughts, step 8 took me about 2 hours of trying and i think i broke the thing but i broke it in a way where it works , its like crushed in..... never again will i try to fix my mouse if it double clicks , the guide is not bad, but doing it is, point.... DON'T TRY</p>
<p>Saved a $5 mouse.</p><p>The mechanism cover, from steps 5 and 6, was placed on this board in such a way that only one side was available. I had to lift the only exposed side, then push a small stiff wire through the mechanism box against the far side in order to safely open it. It was like a jack-in-the-box.</p><p>Thanks for the simple and fun instructions.</p>
<p>I have found a much easier solution to this problem. Just put a small piece of paper in the space between the mouse button and the mouse. This will fix the problem to quite an extent and is a much easier solution. Albeit it may not work for all mouses</p>
<p>I can't believe it but I was able to do it!!! Saved a $80 mouse! These instructions and comments are great! Thanks so much!</p>
<p>The idea is to keep the same pin angle, but flattening the curve so the pin is slightly longer. This is what will increase the tension. Also once you know the trick for putting the spring back, it's really fast. First one took 30 minutes to figure out, second one took 1 minute. I've drawn the steps because it might be clearer than having the real pictures, focusing on the important parts</p>
<p>The drawing helped me alot dude, thanks for taking your time to do this. At first it took me like idk 40min to figure out how to put the copper thing back in plase, but after I saw your drawing it took me like 10 min to get finished. Thanks again! :D</p>
<p>Your drawing help a lot !</p><p>Thanks a lot and have a nice day!</p>
<p>Thanks for the diagram! You're the only person who was smart enough to draw a simple diagram. Putting the copper piece back in is really a two-step process.</p><p>The second step that I missed, is pushing the curve straight down until it clicks into place.</p>
<p>I am using the Gila GX mouse <a href="http://www.geniusnet.com/Genius/wSite/ct?xItem=55373&ctNode=3605" rel="nofollow">http://www.geniusnet.com/Genius/wSite/ct?xItem=553...</a> and I did all the steps without problems but now the mouse isn't working. <br>When I plug it into the pc, the lights blink once for few milliseconds. So it does know that it is plugged in, but when I click/move the mouse, it doesn't do anything. <br>I'm pretty sure I haven't damaged any internals and I've reinstalled my drivers. I've also restarted the pc a few times but the mouse is still not working.<br>Does someone know what the problem is?</p>
<p>That resolve one of my problem with my Logitech G700!</p><p>&quot;Step 8: reinstall tension spring&quot;</p><p>WOW !</p><p>You are surely not one of the more miser guys (like Bill Gates) on this planet) to teach us free!</p><p>Thanks a lot and have a nice day !!!!</p>
<p>Do people really not know what a microswitch is? Why does everyone call it a &quot;click&quot;? I guarantee you that if you tell someone in an electronics place that you want to buy a &quot;click&quot;, they'll look at you like you're nuts.</p><p>As for the tutorial itself: I find that when my mouse starts double-clicking, the solution is usually to clean the contacts in the microswitch. The spring is usually fine and after cleaning the contact points with a Q-Tip soaked in alcohol, it works great for 6-12 months.</p>
<p>Well, this is Instructables. If you want more in depth and nit-picking analysis, I'd recommend hackaday.</p>
<p>Thank you! I have 2 logitech mice and BOTH have started having this problem. I might replace the switch if I can find or build a better one that lasts longer. At any rate, once the mice die for good, no more cheaply made logitechs for me. One year then broken is designed obsolescence. I won't be supporting a company that does things like this.</p>
<p>Just awesome! Fixed the annoyance that I've been having since months!!</p><p>Thanks :)</p>
<p>Big thanks. Took me 5 minutes and it was fixed.</p>
<p>Thanks fixed my mouse after about 20mins the clicking sounds gone but atleast it doesn't double click when i single again</p>
<p>Thank you so much!! You saved my life, LOL!! </p><p>It really works. You are genius!! Be happy and keep helping others by give such helpful solutions!!</p>
<p>Here are two very close up pictures I had from my Intellimouse Optical USB. They are very similar to the ones all of you have shown. Hope this helps someone to see it close up.</p>
<p>I actually ended up swapping the switch with another one from my other Intellimouse Optical that wasn't working for a different reason.</p>
<p>Thanks for nice document. I tried repair my Logitech G700 by following this instruction and it seems to be working better than before.</p><p>During fixing it I felt that OMRON's click mechanism is not perfect and there should be more safe way to give a tension to the left click button...</p>
<p>Thanx a lot :)</p>
Thanks for this. My m570 made it so I had to remove a tiny circuit board to get to the left click box. It's like they don't want you to fix things!
<p>Thanks so much. Works really well now. Have a nice and firm click to it. I had to open the right click button also to have a reference of how it should look. easy useful fix</p>
<p>Just replaced the clicker with one from an old a4tech mouse. Works great. Get a desoldering iron if you haven't already.</p>
<p>Created an account just to thank you. It was a meticulous process but your instructions helped a lot in fixing my mouse. More than saving money it was a great experience, especially since I love DIY stuff with electronics. Thanks once again. :)</p>
<p>I have a G700S and found by taking the batteries out and clicking both (left &amp; right) over and over for about thirty seconds it went back to working again (no double-triple clicking) seems the capacitors need to be discharged....it surprised me that it did work....thought I'd have to take it apart and re-bend the copper contact.</p>
<p>I just wanted to say thank you, it took me a good 45 minutes of taking it apart and putting it back together again to get it right. But I still really appreciate it!</p>
<p>It worked !</p><p>Most difficult part was inserting that white button.</p>
<p>It worked !</p><p>Most difficult part was inserting that white button.</p>
<p>Thanks a lot for the guide, my Roccat mouse now works like it's supposed to!</p><p>It's quite fiddely and took me between half an hour and an hour. I had to disassemble the right mouse click to figure out how it was supposed to look like. But it was okay, I ended up figuring it out.</p><p>Note that you can retension the copper &quot;spring&quot; without removing it! In my case, I removed it and flattened it like on the pictures but couldn't put it back in. When I managed to do so, it was a pain because it wouldn't click correctly. I ended up pressing down on the whole thing with a finger, and pushing up on the spring to flatten it with the click still assembled. Which I should have done in the first place as it would have spared me a lot of trouble putting it all back together.</p><p>Thanks a bunch for the guide!</p>
