A Switch is a toggle button that can be switched on (checked) or off
|
||||
(unchecked). Switches are typically used to represent features in an
|
||||
application that can be enabled or disabled without affecting others.
|
||||
|
||||
On mobile platforms, switches are commonly used to enable or disable
|
||||
features.
