What is this button-like clickable metal, on a PCB, called?

When I receive prototype from supplier, I see a button-like clickable metal on it. Very interesting. What's that?

It’s called dome switch.

To use this switch you will need to:

  • Decide actuation force
  • Size of the switch
  • Select a switch — try a few different types before you pick one.
  • Implement contact footprint in PCB compatible with the dome switch.
  • Get the dome switch or it’s assembly (dome switch stuck to a plastic film. Lay it down on PCB after SMT process.)
