Question

Do it yourself

What is the name of the button mechanism with the spring bringing the anchor of the contacts?
For example, let's take for example an ordinary mikrik, and an ordinary clock button.
In an ordinary tact button, however strange it may seem, one can also say that when arching, the cup presses, thus, as if there is this effect of a leading spring.
But here in the mikrik, it is better seen, there is a spring that flips the anchor of the contacts from normally closed to open groups.
So what is this mechanism called? (Google seems to have banned me)

Answer 1

Instantaneous mechanism, sort of. Or - prevention of a bounce of contacts.
