Mini Silent Micro Switch, Used on Mouse middle button,micro switches with red buttons
Those are generally called "Tatctile switches" because they are (almost) silent, just mainly felt when you push the button. Almost any tactile switch you can get from farnell or ebay in that form factor would be near silent
They may look non standard, but they are the same dimensions as OMRON switches
which means that you can put them into most Logitech mice, and it should work/fit
here is my Logitech mouse with Kailh switches
Microswitches on the other hand are louder, though my mouse has microswitches instead of tactile switches, but it does make a nice audible click as you push the button.
