Logitech MX Ergo: What type of switch is used for the multimedia buttons?

Wed, 31 Dec 2025 04:35:21 -0700

The multimedia buttons (or browser forewards backwards buttons) have broken on my device.

More specifically, the forewards button does not spring back to its origional position.

I've opened it up, but I wouldn't have the slightest clue what switch it is. Prefferably I'd like to replace the little print plate, as it seems to be seperate and connected through a cable, but I haven't had any luck finding replacement parts...

Hi Team,

My MX Master 3 mouse scroll wheel click is not working properly. I used to work with CAD designs, for that i need to press hold the scroll wheel to rotate the cad models. Recently i am facing this issue, while holding the scroll wheel press is not holding properly. I am pressing and holding it very hard. I think press button for scroll wheel is damaged. If it is the case, please let me know how to repair or replace it. Appreciate your support and solution.

Logitech MX Master 3S: MX Master Left Click Replacement?

Fri, 14 Nov 2025 08:28:41 -0700

Using an MX Master 3s - need to fix/replace my left click switch or spring. Can someone point me towards my options? Whatever is easiest is best. I don't really want to deal with soldering, but buying a new $100 mouse also seems out of the question.

Logitech MX Anywhere 3S: Wheel does to not respond to clicks

Fri, 14 Nov 2025 08:09:32 -0700

Hey there, I've had my Logitech MC Anywhere 3S for about a year now and rather suddenly clicking with the middle mouse no longer works.

Some trouble shooting I've already done. I've used the mouse on another computer (same issue) and I've confirmed my drivers are up to date, If anyone has any ideas on what could be causing this issue please let me know! Thx.

Logitech MX Master 3: Middle click randomly not working and some time it would double click.

Mon, 16 Jun 2025 15:07:31 -0700

The mousewheel click would randomly not work unless I pressed it harder than normally. I also noticed that if mashed the button repeatedly it would work normally as if the mashing was priming/warming it up to work normally.

Logitech MX Master 3: MX Master 3 not responding randomly

Mon, 03 Mar 2025 02:53:08 -0700

I have my MX Master 3 for 2 years now. Recently while using it normally it stops responding for few seconds and then goes back to normal. Not responding no buttons and no movement of the cursor is happening.

This is happening regularly lately and don't know the reason and how to solve it.

It is not a battery issue (i think) as the mouse is fully charged.

Logitech MX Master: Not Charging? The 3 lights don't light up.

Fri, 14 Nov 2025 08:29:30 -0700

My MX Master( M-R0052) seems to work fine but the charging lights don't light up when plugged into a known good cord and power source. Is there a way to know if it is still charging other than waiting for the battery to go dead? Which board might be suspect? The Battery is a new battery.

Logitech MX Master 3S: Can't get the ribbon cable in

Mon, 09 Sep 2024 14:34:44 -0700

The lock broke and I can't get the ribbon cable back in. Am I screwed? The cable came out super easy and nothing had broken. Trying to get it back in has been like wrestling an eel. The lock fell off and the ribbon cable won't slot in no matter what I do. I can get the lock back in without the cable and it stays. Can't get the cable in though.

The idea of do it yourself repairs is a nice idea, but nothing stresses me out more than ribbon cables and jst terminals.

Logitech MX Anywhere 2S: Automatically scrolling on the horizontal direction (to the right).

Thu, 11 Jul 2024 05:08:06 -0700

I am a Mac user.

When hovering the mouse over a window showing the horizontal scrollbar or over an accordion component, scrolling takes place by itself.

Same behavior on Bluetooth or USB connection.

Other mouses (Logitech and other brands) do not have this behavior, on the same macbook (bluetooth or USB connection)

I opened the mouse and removed the wheel, the same behavior.

Is it an electronic failure or can I do something else to solve the problem?

Logitech MX Anywhere 3: Disassemble mouse wheel unit

Tue, 19 Mar 2024 10:42:15 -0700

The mouse wheel unit seems to have some dust or hair stuck in it, reducing the wheel's ability to spin. How do I take the wheel out to remove dust?

Also, while attempting to figure out how to do it myself, I removed a spring from the bottom of the unit. I cannot figure out how to put it back. I reassembled the mouse without it and it does not seem to affect functionality, but I'd like to put it back anyway.
