Props

Name	Type	Default	Description
aria-describedby	string		The id of the DOM node that describes the switch
aria-labelledby Required	string		The id of the DOM node that labels the switch
defaultChecked	boolean		Uncontrolled - whether the switch is turned on
disabled	boolean		Whether the switch is ready for user input
loading	boolean		Whether the switch's value is being calculated
checked	boolean		Whether the switch is turned on
onChange	(on: boolean) => void		The callback that is called when the switch is toggled on or off
onClick	(e: MouseEvent) => void		The callback that is called when the switch is clicked
size	'small' \| 'medium'	'medium'	Size of the switch
statusLabelPosition	'start' \| 'end'	'start'	Whether the "on" and "off" labels should appear before or after the switch. This should only be changed when the switch's alignment needs to be adjusted. For example: It needs to be left-aligned because the label appears above it and the caption appears below it.
