Replacing the Left Button Switch on a Logitech MX Vertical Mouse

I use Logitech MX Vertical mouse and have been since its launch. The left mouse button recently developed an issue where it would intermittently not remain pressed or it would register two presses in a row. A little internet research indicated this was a somewhat common problem with the switches used in the mouse and the fix would be to replace the switch used for the mouse button.

TRY THIS BEFORE OPENING THE MOUSE. For those also having problems with the left button (erratic drag and drop, random double clicks), first try blowing compressed air under the mouse button (avoid air from your mouth). I saw this solution on a Reddit threat and this solved the problem for me and for many people in the thread. Sometimes it is just some dirt on the contacts.
Nice video though. Very thorough 👍

Thanks for this video! Mine is playing up too... and after watching your video and seeing how easy it is... I'm buying a new one 😀

I just sprayed some contact cleaner inside the button's hole, pressed on it about 20 times, and dried with compressed air. Worked like new. WIll need to order those switches so I'll be ready next time. We have quite a few users using this model at the office.

Awesome! I've just used your video to give me some assurance while changing my mouse's left button. Now, after changing the left button as you show, it's not having failed clicks and intermittent drags. Thank you very much!

I just did it. It was not so difficult with such a clear walk through. Thank you.

Thank you for such a clear and detailed walkthrough! I've had a stack of these mice building up, since the clicker keeps breaking on each one after about a year. I don't have any experience with soldering, so I figured I better try doing two of them to see if one might work. I burned them both to high heaven trying to get the old switches out, and I killed one of them, but the other one works great now! I never would have tried it without your guide here!

Thanks just followed your video and replaced both left and right switches while I was at it. Worked like a charm. No more double click problem and not holding the click

This video and comments section is gold. Wish I had thought of looking for a solution last year. Thank you!

boy, they really didn't make this easy, did they. Thanks for the walkthrough!

Thank you very much for this video. I had two MX Vertical mice with the left button not working reliably with click-n-drag. My first attempted fix failed. I had trouble getting the old solder off after removing the faulty switch, likely because I did not have any solder wick and I probably overheated that tiny board. Maybe I'll try selling that one on eBay for parts. I bought a slightly used one off eBay for just under $50 to replace that one. After buying some solder wick and paying more attention to how you did the soldering, my second attempted fix worked. The MX Vertical is my most favorite mouse. For $100 I wish Logitech would use better switches--I'd gladly pay a few bucks extra, rather than do this repair again... so many tiny screws.

Thanks! You have a great voice-over manner

Thanks for the inspiration, I've just fixed my left button :-) Switches ordered from Czech eshop, no problems to find some.

Merci pour cette vidéo. Je viens juste de terminer le changement du contact de clic gauche et tout fonctionne de nouveau à merveille. Je n'ai pas trouvé le switchs sur amazon france mais sur amazon allemagne et ils les vendent par 10. Bravo !👍👍👍

Great video!! repaired my mouse on the kitchen table.

[GameFactsSpecial]

Great video... this happen to my mouse after about a year and a half put a few pieces of electric tape on top of the clickers and it works again!

[algalvision]

very comfy video, thanks a lot man! I got an mx ergo from work but I like the vertical too much to have to throw it away, feels pretty much new now

[OriolSierra]

cool, good explanation. I did all steps but unfortunately I messed it up with the soldering portion... I burnt the contacts while removing the solder! For inexperienced people like me maybe it's good to make some trials on the side before trying to de-solder. Had fun anyways! :)

[silkyjoe]

Thank you! I was so unhappy when mine started having this issue.

Thaks so much or your video! replaced the left button, now its good as new!
