`GtkSwitch` is a "light switch" that has two states: on or off.

The user can control which state should be active by clicking the empty area, or by dragging the handle.

`GtkSwitch` can also handle situations where the underlying state changes with a delay. See [signal@GtkSwitch:GtkSwitch:state-set] for details.
