Could the time change the "clicky" sound of a switch ?

[Retrete]

Hi! Few days ago I bought a 2nd hand (with heavy marks of use) acer 6312-ta ,like this one but with the old acer logo ;


I also have a benq 6312-ta ,exactly like the one of the top
Comparing them head to head I noticed a different "clicky" sound , acer one is softer and less noisy than the benq .
The acer kb mounts their own keyswitches , and the benq looks exactly the same but with no acer logo on them .
The benq switch ;


I've read that the benq use Alps black , that's true ? so , alps black=acer switch?
I will upload a video in a few hours , "la duda me corroe"

The Alps Black is a different switch than the Acer switch. The Acer is clicky while the Alps with black slider is not.
The acer switches can feel a bit different depending on how hard and fast you type on them.

Def acer-benq 6312 switches are not the same; the proof:

Deu!

Is it just me or is that white keyboard squeaking?
