How exactly do cherry switches work?

[maximus20895]

I am pretty new to mechanical keyboards in general and to be honest I have never even used one. I have read the mechanical switch guide and most other wikis, but I still don't know exactly how the switches work.

I don't know what they look like inside, or how it sends a signal, or how the brown, blue, black, white, etc differ physical from one another.

Is there a post that shows the ground work of switches or anything of the sort?

Thanks!

You could look through the Wiki.

This is how blues work apparently:

The yellow parts are the electrical contacts. I can kind of see how it works, but I understand the Alps and buckling spring mechanisms  better.

Hmm we should start a "how switches work" wiki article.

[msiegel]

with links to patents in it? that would be cool

but I understand the Alps and buckling spring mechanisms work better.

Please elucidate. IIRC alps have shorter lifespan.

They are simple switches. Normally open, and closed when you press a key down. If you dissemble a switch, removing the plunger, the circuit closes.

As mentioned by Pylon, the wiki page is useful. Linked there is Qwerter's Clinic, which in pictures explains it.

Check out the graphic for how the Brown MX actuates, and the comparison of other switch profiles. The plungers determine the actuation characteristics, when combined with a certain spring.

Stupid typo on my part (edited). I meant that I have a better understanding of how they work compared to Cherries.
