Are there any brands of silent (or close to silent) micro switches? The typical ones are very loud and thus aren't good candidates for mouse-like equipment.
Micro switch type I'm looking for

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
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.

Tact switches like on the picture are very bad idea for "mouse like applicatoans" as they work not so stable as should, have short life and overall feeling while pushing them won't be good. Only right choice is proper microswitches like those http://www.ebay.com/itm/2Pcs-Micro-Switch-OMRON-D2FC-F-7N-10M-For-Mouse-New-/251336866229?pt=LH_DefaultDomain_0&hash=item3a84d839b5 (http://www.ebay.com/itm/2Pcs-Micro-Switch-OMRON-D2FC-F-7N-10M-For-Mouse-New-/251336866229?pt=LH_DefaultDomain_0&hash=item3a84d839b5)

It needs to be the same type as shown on the photo, so that omron won't fit.
Googling for tactile switches then -- found Omron B3F-1002

My Hama twister mouse has just died as well due to the use of tact switches but as it was 7 years old I wont hold a grudge against it, the tact switches were not of the usual type either so I could not find replacements. Just ordered anothe wireless mouse meanwhile I have to put up with a rat that I keep just in case.

Grab those out of an old cheap mouse, you will probably find one that has the right switches if you look through a pile of them in a ewaste pile.

I have some B3F-1050 which are same as B3F-1000 just taller. Seem to be quieter that average. And they are with lowest operating force (0,98N) in B3F series. B3F-1002 is 1.47N however. Take in account that lower force switches have longer life than high force ones. B3F-1000 has 1 000 000 operations durability, while B3F-1002 only 300 000

I prefer the click. But that's just me. I used to use a Model M keyboard for a little while at one job. I loved it.

Anyone knows where I can find this type of switch, but normaly closed. Means, it opens when pressed. :-//
