This interface has both a toggle switch and a light indicator next to it. Both state and action (ish). The light is independent of the toggle and shows the current state, which is why they mentioned a delay - clicking the toggle doesn't immediately change the light indicator next to it, clicking the toggle tells the system to turn it on and the toggle changes immediately to show desired state, and only after the system changes and sends back "I'm on now" does the light indicator change.
