/**

 * Constructor for a new Switch.

 * 

 * Accepts an object literal <code>mSettings</code> that defines initial 

 * property values, aggregated and associated objects as well as event handlers. 

 * 

 * If the name of a setting is ambiguous (e.g. a property has the same name as an event), 

 * then the framework assumes property, aggregation, association, event in that order. 

 * To override this automatic resolution, one of the prefixes "aggregation:", "association:" 

 * or "event:" can be added to the name of the setting (such a prefixed name must be

 * enclosed in single or double quotes).

 *

 * The supported settings are:

 * <ul>

 * <li>Properties

 * <ul>

 * <li>{@link #getState state} : boolean (default: false)</li>

 * <li>{@link #getCustomTextOn customTextOn} : string</li>

 * <li>{@link #getCustomTextOff customTextOff} : string</li>

 * <li>{@link #getVisible visible} : boolean (default: true)</li>

 * <li>{@link #getEnabled enabled} : boolean (default: true)</li>

 * <li>{@link #getName name} : string</li>

 * <li>{@link #getType type} : sap.m.SwitchType (default: sap.m.SwitchType.Default)</li></ul>

 * </li>

 * <li>Aggregations

 * <ul></ul>

 * </li>

 * <li>Associations

 * <ul></ul>

 * </li>

 * <li>Events

 * <ul>

 * <li>{@link sap.m.Switch#event:change change} : fnListenerFunction or [fnListenerFunction, oListenerObject] or [oData, fnListenerFunction, oListenerObject]</li></ul>

 * </li>

 * </ul> 



 *

 * @param {string} [sId] id for the new control, generated automatically if no id is given 

 * @param {object} [mSettings] initial settings for the new control

 *

 * @class

 * A switch is a user interface control on mobile devices that is used for change between binary states. The user can also drag the button handle or tap to change the state.
