Introduction

It's an easy procedure to fix the problem. You can watch the mouse being disassembled for more help.

  • Take the mouse shell apart, held by 4 screws
  • Unsolder and replace the micro switch

I have found 3 different manufacturers which sell micro switch replacement part for Logitech Anywhere. I only have tried E-Switch.

2 screws are located under the battery stickers. 2 screws, one under each of the sliding pads under the mouse's nose.

Peel off the battery sticker to reveal 2 screws. Remove those screws with a phillips screwdriver.

Lift the upper shell away from the base. No cable connects the two parts.

Desolder the micro switch and replace it with a new one, E-Switch TS20100F070S I use a Weller ST7 0.03" X0.79 mm ST Series Conical Tip to remove and solder the micro switch Just remember, the micro switch doesn't have a polarity. But the connectors will guide you which side the micro switch needs to face.

Everything fine to this point, but I found desoldering the microswitch that it's too easy to actually pull off the pad it's soldered too, leave me a nice little square of PCB that I couldn't reconnect anything too.. which then required removing the entire PCB board (some tiny parts). I should have started at the top and worked down, but i tried to pull out the wheel without removing the top board and broke part of the anchor/swivel - not going back together now!

corrupted PCB is fixable ( i have fixed also pair on Logitech MX), and anchor-swivel depend on damage. If you are interested on repair, email me at info [at] skfree [ dot] sk. I am doing also other types of repairs on LT anywhere MX mouses and changing of microswitches also.

Yup I had the same problem. Solder pads went off when de-soldering the switches.

Do you have any pcb traces layout to reconnect the solder pads again?

Thank you very much.

I found a way to remove the old switch without damaging the solder pads. I used a Hakko CHP-170 micro wire cutters to snip the switch solder leads right at the body of the switch, and remove it. Then I carefully removed the remaining solder tabs with a small sharp razor blade knife. Only thing you got to be careful of is not to scrape through the solder pad. Solder is pretty soft to cut, and it is less risk to mechanically remove the switch than apply heat unless you have the right de-soldering rig.

BTW, Digi-Key and Mouser are out of stock on the E-switch PN. I am back ordered, so will use mouse with a tail until parts arrive.

Thanks Carl! Clipping the switch leads, then desoldering the remaining bit worked for me. The pads are *very* susceptible to lifting, so be cautious. The pads need to be well cleaned to allow the new switches to fit down snug to the board.

**** To avoid damaging the solder pads ****

The switch is soldered with ROHS, which has a high melting point. Before trying to actually desolder the defective switch add some good ol' non-ROHS solder to lower the melting point of the original solder. Then use a solder absorbing tape. I've fixed 4 mice so far with zero failures, first one desoldered twice.

Many many thanks to the author for providing the part numbers of the replacement switches. Couldn't have done it without those.

I prefer to open upthe micro switch

Then polish the ball end of the brass

No need to welding any part!

Cause the current make the little spot of the brass scorch

Thanks. Excellent guide.

Thanks, my mouse actually arrived out of the package with the double-click issue, and this fixed it. Needed pretty high-temp soldering iron to get OEM micro-switch off, and tight fit soldering the new one on the inside terminal, but otherwise pretty easy.

Got this mouse, had this problem, sent it off for an RMA. The one they sent back eventually developed this exact same issue. Here's to hoping I won't have to do this again for a while now. Thanks for the guide.

Ended up having to repeat the process for the right mouse button. This time I managed to knock off one of the solder pads. Eventually by applying a lot of pressure and heat though, I was able to get the switch to bind with whatever was left of it, although I still have no idea how long my fix will actually hold for. But, something to watch out for if you're doing this.

This is great as now i have a part number as when I pulled the original microswitch apart to fix it internally, the button flew away - never to be found.

These are great prices for little switches, however living in the UK means an expensive courier to £15 and a lounge wait. They simply do not sell these here in the GB :-(

The part with shipment is far cheaper than a brand new MX Anywhere mouse.

Thanks again for the info!

Great guide. Although I managed to repair the microswitches following this video: https://www.youtube.com/watch?v=82z-OpHd.... That guide is for a Performance MX, but the part about fixing the switches worked for me on the Anywhere MX although the switches are a different model.

Be very careful when opening the switch as it's easy to damage the cover closing mechanism, so when you put it back together it no longer snaps in place. I did that on one of them, and had to use a couple drops of loctite to hold the cover down but it worked out great still. Also when you open the switch be careful about the metal spring inside as it may easily fly out and get lost.

It was a bit fiddly, but it ultimately saved me delivery time and money for new switches, and the buttons now work perfectly again. Plus, if it fails you can always just desolder them and install new ones.

This worked great. Under 5 bucks for parts (if you already have the solder iron), and a new mouse is the result. Great stuff, thank you!

Why go through all the extra steps (and potential for problems) by desoldering the entire defective switch and replacing it with the new one? Simply open the defective switch and the new switch and take out the defective copper spring and replace it with the good copper spring from the new switch. If a piece goes flying (the white button or the spring), use the new one as a backup. Going through all this extra hassle is begging for problems. Also, don't bother trying to repair the curve on the defective spring. You'll never get it 100% perfect as new. It WILL fail again eventually. So just swap out the springs and move on with life. If you screw up the switch covers, you can use black electrical tape to seal the edges. Don't use glue.

Awesome, thanks so much for this guide!

*** Just a heads up guys - do a continuity check before ordering the tactile switch. It may be just a cold solder joint just like mine. Fixed it under a minute.

Tons of posts about the main front switches. Zero articles about the side switch and their part numbers. :(

You can find them on ebay. They sell as repair kit. If somebody is planing to open his mouse, can he/she put the mesurement on this post?

Since the described switches replacement procedure required periodically it is advised to screw back only the screws at the tail of the mouse. That is enough. And in that case you should not replace the foot gliders every time.

Nice hint, thanks!

Shinn Thanks for the ebay link. I also opened it to check. Side small buttons ( same as middle button ) measures 5.2mmx5.2mm footprint is about 2.5mm spacing in center, 4.5mm outter edge to outer edge, actuating height unpushed is 1.5mm. The ebay link doensn't provide part number but digikey has close approximations just a general description as ALPS Mini Push Button. Search shows it might be a ALPS SKQGABE010 which shows 5.2x5.2x1.5mm 160gf. I think those are it ! THANKS for the help.

Thanks for this guide! It was very insightful to check out the mouse from the inside!

Just got my Omron switch in, all works well now and wanted to thank you for the description and pictures.

My repair was complicated by my lack of soldering skill, I accidentally broke loose a chip of copper under the outer solder pad, and struggled a bit to scrape adjacent area down to copper trace to allow an electrical connection. In my efforts, I actually took the board out completely to see if the traces were visible on underside, that did not help. But I got to learn how ALL the tiny bits & scroll wheel get assembled. To be clear, if you break off the switch solder pad, it does not help to disassemble the mouse, just scrape to expose some copper and flow the switch leg joint solder toward that.

Afterwards, I was surprised it worked at all, as I had bunged things up pretty good, but the new switch fixed the “double click” issue and I’m happy!

Hey mate can you tell me please which exactly spot should i scrape and how?? i have same problem. Please check my link https://imgur.com/a/re0P8 its a photo of the damage. and if is possible open it with paint and draw some signs about the spots for scrape to understand and send me if you want.
