The Logitech Mouse Double Click Problem and How To Fix It!


logitechmouse The Logitech Mouse Double Click Problem and How To Fix It!

We’ve long had a love hate relationship with Logitech mice. On the one hand they’re ergonomically designed and feature the wonderfully useful hyperscroll wheel for sweeping through documents and web pages, but on the other they suffer from a fundamental fault after a few years of use, when the mouse buttons start to fail (note that other mice also seem to suffer from the problem, although we’re not sure whether that’s because they’re OEM models made by the Logitech factory).

Despite our rant four years ago, little seems to have changed, and the other day yet another mouse here, an  M705, started failing again for the same reason. The symptoms are that the mouse click delivers two clicks for one press, which can be extremely annoying and renders the mouse unworkable for important tasks. This time, however, instead of consigning the device to the trash and buying another, we decided to see if we could solve the situation with a bit of DIY. And the answer is yes!

A quick search on Google revealed that other more intrepid souls had managed to fix their own meeces, and so we got to work on two ‘dead’ mice lying around in Ferret Towers, a Logitech M705 and an older MX Revolution. The first thing to note is that the culprit is tiny, a sliver of copper which can’t be worth more than £0.02p.

The actual spring mechanism is a tiny piece of intricately designed copper (top left in the image above) which sits inside the black microswitch housing on the right. What seems to happen over time is the copper flattens out through repeated clicking and once that happens, you start getting unpredictable results and double clicks etc. To fix the problem, you need to dismantle the mouse, open up the black switch casing and restore the bends in the copper to the original shape.

It’s hard but not impossible to do. You’ll need a steady pair of hands, patience and a small screwdriver and thin knife or blade. I fixed the two mice, the first took me 2 hours or so, the second (the M705) one hour. To be fair, I’m including here a link to the original Overclockers.com forum post I used, where they fixed a Logitech G7 mouse, so I won’t repeat everything. Just give a quick overview of the task for the M705. Click on the thumbnails to expand the image. [Update: I have now added this video below, to try and make things a little easier. Hope it helps.]

Oh and the usual disclaimer: You do this entirely at your own risk, DO NOT attempt it if you’re not at ease with electronic DIY and we are absolutely not responsible for what happens to your mouse, warranty, lifestyle or flowerbeds as a result.

The key thing to read and remember by the way is this comment. It is essential that you restore that tiny curve at the end of the copper mechanism before reinserting it.

Steps.
1. Unplug and dismantle mouse. You’ll usually find around 5 screws under the rubber feet and/or under labels. On the M705 they’re as arrowed below.

2. Once they’re removed you just carefully prise the mouse apart, taking care to gently remove the connected wire from the side.

3. Once open, you’ll see the switch boxes (left and right mouse buttons) in front of you. In most cases the most common problem will be the left mouse button since that gets used the most.

To remove the switch box cover you’ll need to get a thin blade under the catch on the sides (A), and gently (careful, they break!) lift the top (B) away from the switch body and upwards to prise it open.

My earlier attempt on the MX Revolution mouse below (easy to scratch the cover getting it off, especially if you’re clumsy like me, but as long as you dont break the end catches, it’s fine.

4. Once open, you’ll see the copper switch, which you remove with a gentle sideways push to dislodge it from its position.

5. Now make sure the copper spring switch is flat, but with the nice curve on the middle curved part and a upward kink at the end as per the forum post above. The copper is very thin and malleable, so be careful, you can break it with just a bit too much pressure with your finger nail. In fact just a gentle tweak with a fingernail edge or a pair of tweezers is all you need.

6. To insert the copper spring back, put the front part of the spring back first (A), then gently curve the rear upwards and slide the whole thing into place under the rear catch.

The thing that confused me the most, until I opened the other switch to compare, is that the spring at point (A) actually slots into a tiny slot which catches and holds it. The other end just slides under the catch, so it’s different at both ends. Then the curved bit in the middle (C) slots into another slot in the middle to give the whole thing some tension. The end result should be that you can press down on point (B) and hear a distinctive click. If you can’t the thing isn’t installed properly, so you’ll have to keep fiddling until you find the tension.

See this video to get an idea:

and here’s my close up video of just refitting the copper spring which should also help –

This bit is undoubtedly the most fiddly part of the whole exercise, but once you get it right you’ll not forget for the next time. If you get stuck, re-read the whole of the above forum post again, all the clues are in there.  If you lose the spring in error (they do tend to ping away if you’re not careful, you can pick up spare switches from eBay which should have the same copper spring inside.

7. Finally, reassemble the mouse in the reverse order and give it a test. You’ll be amazed at the fact that the thing works again properly. I should also mention that the forum post mentions a free software utility called MouseFix which is supposed to fix the problem with double clicking mice, but it’s very old and there’s no guarantee that it will work with anything other than Windows XP. Good luck.

    A quick tip to help with putting the cover and the tiny white bit back on: put a small patch of adhesive tape on top of the cover where the slot for white clicker thingy is. Then just push the clicker in and it should stick to tape. That way you can mount it again without it falling out.

      Excellent tip, thanks.

    God bless you for this, I was just about to throw my mouse through a wall.

    • http://www.redferret.net/ Nigel Powell

      Heh, glad you didn’t and happy we could help. :)

  • Karim

    Awesome! No more double clicking issue :D you saved me and my wallet lol thank you very much!

    • http://www.redferret.net/ Nigel Powell

      Our pleasure. :)

  • Steve

    Excellent write-up. Thanks. I experienced a similar problem with a similar mouse (Sumvision Paradox III). It’s about 2 years old and gets a good 5 hours use a day.The switch works in the same way, but it is a slightly different shape. I took the cover off the switch and sprayed PCB (non deposit) cleaner over the contacts whilst operating the switch with my finger nail. I didn’t need to re-bend the spring. Problem solved. I found a pin was the best tool for lifting the snap down switch cover lugs.

    • http://www.redferret.net/ Nigel Powell

      Thanks for the feedback. Great idea about using the pin. :)

  • XR400

    Wanted to pass along my thanks. I have the M705 mouse. Followed your instructions carefully and was able to eliminate the bogus double-clicking issue.

    Hi,
    do you have more pictures? I have a problem that the scrollwheel does not make the button-click sound when I press it. I disassembled the mouse but I haven’t found anything relevant. Check
    http://i60.tinypic.com/303by2w.jpg
    It is not a button, it is just some touch sensitive spot. Was there any other part that could fell out?

    Thanks

      I’m not sure what that could be. I have never had that part fail on me with any other Logitech mouses. Sorry.

  • Mike

    I did everything here, and when I press on the middle bar of the copper pieces, I get the desired click. When I screw everything back together, though, the buttons don’t click. Any idea why?

    • http://www.redferret.net/ Nigel Powell

      That’s really strange. If the copper clicks, the button should click as well. Hmm…are you sure it’s a proper click and not just a flex you’re hearing?

  • mouse

    thanks for the detailed tutorial. this saves me 50 USD and i will not buy any logitech mouse.

    • http://www.redferret.net/ Nigel Powell

      Oh but they’re **great** mice. I love them. This is their only fault as far as I’m concerned.

  • ilie

    I fixed with this operation a logitech v220, now it works as new. The next time i have this problem i might try to swap the two thin copper metal piese betwen the left and right button. (The right click metal piece must be as new, no ?)

    • http://www.redferret.net/ Nigel Powell

      Yes, I think that’s a great solution to swap them. Although it is twice as fiddly fitting them back in. :)

    Spray WD40 is magic for many problems, inclusive volume wheel in
    headphones with rac rac rac noises, also for repair this problem of
    mouse clicks…
    Test, is a very fast, not need open the mouse or open the headphones, spray and go well another time…

    Very Nice, it really helped me

  • Daniel

    Worked like a charm to fix the double clicks, only took me a few minutes due to my previous attempt on a Logitech G5. Also had to cut a small piece of Styrofoam to slide under the left mouse button, it didn’t seem to want to bounce back up after clicks.

    • http://www.redferret.net/ Nigel Powell

      Cool. It definitely does get easier if you do it more than once. The Styrofoam sounds interesting. :)

  • Rick Shin

    I love Logitech mice for their ergonomics and functionality, except for this problem. Does anyone know of a Logitech model that’s not prone to this issue?

    • ThereIveSaidIt

      Nope, they’re all prone to it. I have been using Logitech mice for around 10 years and it’s only in the last 5 years or so that this problem has arisen, as far as I can tell. They have basically downgraded the quality of their products to the point where customers should expect no more than 6-12 months of use from them.

  • Robert Makai

    yay! I also fixed my 59 euro worth anywhere mx! Thanks for the instructions!

    • http://www.redferret.net/ Nigel Powell

      Great, glad we could help. :)

  • ghkj21

    Mouse clicks are VERY firm after doing this. But the issue appears to be Gone :)

    • http://www.redferret.net/ Nigel Powell

      Excellent, sounds like a good result then. :)

  • ThereIveSaidIt

    How about Logitech just acknowledge the problem and fix the damn mice themselves? They have known about this issue for years because thousands have complained about it. I went through 2 MX Anywhere mice which both developed the double click problem after 6 months. After the second one went bad, Logitech – due to a snafu with their warranty department, sent me TWO replacements and they have BOTH developed the problem, one after 4 months and one after 6 months. When you buy a Logitech mouse you have to accept the fact that if you’re a medium to heavy user, the mouse is only going to be good for around 6 months. I believe a class action lawsuit is in order.

  • Chauncey Gardner

    The best way to fix this problem fast is for people to stop buying Logitech mice. I guarantee that the double click problem and software bug problems will disappear in no time! Spread the word on social media – the power of the consumer is highly underrated. I for one am not going to spend time or money on another Logitech mouse. It will take them years to win back customers like me. The markup on mice is outrageous as it is – they should offer a lifetime warranty at these prices but of course, these companies count on continuous product failure to boost sales. My motto is fool me once, shame on you; fool me twice, shame on me.
