# Class OnOffSwitch

java.lang.Object
com.codename1.ui.Component
com.codename1.ui.Container
com.codename1.components.OnOffSwitch

All Implemented Interfaces:
  `Animation, Editable, ActionSource, StyleListener, Iterable<Component>`

public class OnOffSwitch extends Container implements ActionSource
The on/off switch is a checkbox of sort (although it derives container) that represents its state as a switch each of which has a short label associated with it. It has two types: Android and iOS. The types differ in the way that they are rendered. The Android type (the default) is just a button with a label that can be moved/dragged between the two states. The iOS version is more elaborate due to the look of that platform.
