  • The remote control of my TV has two kinds of buttons. There are "normal" ones for the digits etc. which work by bringing a conductive material on the underside of the button in contact with the board of the remote control.
  • And then there are these round silver buttons in the centre for the remote. One pushes their curved surface down to bring it into contact with, presumably, a contact below (not visible from the outside).
  • ![Photo of the board of the remote control. In the centre are 9 round silver buttons](https://electrical.codidact.com/uploads/ukodxdfuhc3ng7w97x09xv478zbg)
  • How is this later type of button called? I don't need a specific part name or number, just a general category name would be helpful.

What type of button is this on a remote control
The remote control of my TV has two kinds of buttons. There are "normal" ones for the digits etc. which work by bringing a conductive material on the underside of the button in contact with the board of the remote control.

And then there are these round silver buttons in the centre for the remote. One pushes their curved surface down to bring it into contact with presumably a contact below (not visible from the outside).

How is this later type of button called? I don't need a specific part name or number, just a general category name would be helpful.
