Mouse scroll wheel sensor - can I buy it?

Question

Do it yourself

I'm probably using mice the wrong way, but all my mice have a wheel that flies very quickly. You have to either buy new ones or buy something for $ 3 and solder the scroll sensor module from there. Such a box is small, where the axis of the mouse is inserted.
So, is it possible to buy a bag at some dx.com or somewhere else? I have no idea what it's called, especially in English, so I can't find it myself.
I would be grateful if someone could tell me where these things can be bought.

Answer 1

It's called "rotary encoder" or even just "mouse wheel encoder". The Chinese have such good stuff in bulk, choose:

Answer 2

Buy a mouse with an optical wheel sensor. Not with an optical scroll, but with an encoder on an optocoupler.
These do not break so easily, at most - sometimes the cracks get clogged with dust, but this is corrected by simply opening the mouse and blowing it out.
