The dynamic button is a switch control withvisual sliding feedback: clicking to toggle ON/OFF, sliding the slider from left to right (or in the opposite direction) to simulate a physical switch. It is most intuitive for operations with a strong "switch feel" such as device start/stop and enabling/disabling.
