radio button为什么叫radio button?

一直很好奇,为什么单选框取名叫radio button,查了一下,

A radio button or option button is a type of graphical user interface element that allows the user to choose only one of a predefined set of options (that's opposite to tick boxes).

They were named after the physical buttons used on older
car radios to select preset stations - when one of the buttons was pressed, other buttons would pop out, leaving the pressed button the only button in the "pushed in" position
