Left click not working randomly

Hi There,

I have a 3 year old MX Master 3, that from time to time does not register left clicks. The click feels normal, but it doesn't happen on the OS. I tried it with Windows, MacOS and iPadOS all with same behavior.

Is it possible to replace the switch?

Thanks in advance,

I am also interested in this. Where can I purchase the switch?

also is the switch hotswap? or solder?

I dont know in your country, but in my country you can find it in online marketplaces

Just try to find 2 pin silent microswitch for the keyword

FYI you'll need soldering iron and tin suction to do that....flux and solder wick for additional for your board safety and cleaning the pad
