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.

You can create a custom appearance for a Switch by

assigning a \l {SwitchStyle}.
