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.
<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>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>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>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>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>
<p>Thanks</p>
<p>Hi,</p><p>Because of the warnings, I first tried all the simple things I could think of before starting to disassemble my mouse.</p><p>I found a very simple measure that worked in my case:</p><p>1. Go to mouse settings</p><p>2. Set double click speed to &quot;fast&quot; (as fast as possible)</p><p>3. Problem solved.</p><p>Of course this might not solve your problem, but it is worth a try! And actually it is not a solution but a work-around. But that doesn't bother me. ;)</p>
<p>Very good tutorial. Cured 3 defunct mice already. </p><p>As they did not last very long even after this process so I swapped the spring/plate (in question) with the one under the scroll bar (I rarely use the click function of the scroll bar so it was as good as new). It has been 2 weeks since, it is working like new.</p>
<p>I did this and i think it worked. My mouse would not always click on the first try and now it does. Thank you. Good stuff</p>
<p>I was having the double and triple click problem. It was static electricity between dissimilar plastics in the mouse design.<br>Try this first cut a small square of heavy duty packing tape and put it over the part of the part of the finger pressure plate that comes in contact with the switch. The part that comes down onto the white post on top of the switch on the circuit board.<br>place the top back on your mouse and test it here. <br><br><a href="http://unixpapa.com/js/testmouse.html" rel="nofollow">http://unixpapa.com/js/testmouse.html </a> <br></p><p>If this doesn't fix your mouse like it did mine then it may be your spring :(</p>
<p>Many thanks. A very well written and illustrated guide.</p><p>I was *CERTAIN* that my fault was owing to S/W but, after testing in Safe Mode, nothing changed. Being mechanically minded, I didn't read every page of instructions because your intro indicated the component on which to concentrate. Over the years, I've &quot;repaired&quot; many electrical switches simply by cleaning so I thought I'd give this a go and chanced it without tweezers. (Complacency on my part!)</p><p>Stage 8 certainly is fiddly especially in ambient, winter overcast outdoor lighting! I had to bother to get out my fine nose pliers! (I've never worked on a switch THIS small) I used a sewing needle (a pin would do) to uncatch the switch housing because of other components obstructing access - that wasn't difficult once I'd chosen the right tool.</p><p>As &quot;Artmis36d&quot; suggested in the comments, I recurved the spring to create a better resistance.</p><p>Perhaps overkill, I affixed a tiny piece of tape onto part of the spring in case it makes contact with the side of the lower contact &quot;post&quot;. That's what I anticipated created the double click: the contacts clearly worked but I imagined that there was a &quot;double tap&quot; of the components during function.</p><p>Mouse single clicks by default, as designed! :-) Have now joined Instructables.</p>
<p>Thanks to this tutorial I have now permanently disabled my 75 euro computer mouse, after about 2h of nothing but rage and salt with only negative results i have decided to leave this comment as a reminder that some of us are not gods, and do not have deathly still hands.</p>
<p>Hello. thank you for the fix. It worked but i have a problem. the clicking is not as crisp anymore, it feels loose if you see what i mean. doesnt feel right . i think i put the click assembly back wrong. if you can help me thatd be great. thanks</p>

<p>very good indeed.</p><p>you could also replace the clicker itself using solder + gun.</p><p>Thank you very much!!!</p>
<p>Thank you for making this repair guide.My logitech g300 have this problem after 2 years of use.Both left and right button has the same problem and it take me around 2 hours to do this.All the pain that i have to go through on step 8 really worth it.My mouse works like new again.</p>
<p>It took me about two to three hours (i'm not so good at fine work like this), but it eventually worked! The clips on the switches were on the side instead of the front, The middle mouse switch was in the way so I had to remove and re-solder the left mouse button switch and use a precision knife to lift the plastic off the clips.</p><p>Thanks very much for sharing this solution!</p>
<p>It worked. Very fiddly but rewarding.</p>
