Kailh Square Silent Micro Switch

I have 2 M220's and a M550. M550 buttons started sticking and missing clicks while the scroll registered double clicks. I wanted to try these on my spare known old M220 that had same issue. despite costing 3X more, Logitech used same buttons in both mice. They work fine for now, time should tell how they hold up. Exact drop in replacement part. Only down side is, you have to know your way around a soldering iron.

Exactly what I needed

I bought the silent switch for logi M750 signature mouse.It’s a perfect fit.

The sound is silent, which I’ve tested, and I still need to install them on my Master 3s; I'll be doing that next week.
