Where can I find "radio button" components?

[supersheep97]

I am trying to build a hifi speaker selector, which will take an input and allow the user to send it to one of three pairs of speakers.

I have a similar unit that allows you to select one of three inputs for the amplifier.

When one of the buttons is pressed, the other two pop back up, the same way that buttons on old radios used to do.

I have tried to find a component like this, I'm not sure what the technical name would be so I've tried as many different search phrases as I can. Does anyone know if and where I can find one?

Perfect, thanks very much! I take it the term I was looking for is "Interlock Push Button" then.

The term "Radio Button switch" is also correct and is still known by it today.
