switch switch selector's Main properties

##Attribute nameBooleanStringEventHandleThe change event is triggered when checked changes, event.detail={ value:checked}

Type	Default value	Description	checked
false	Whether checked		type
switch	Style, valid values: switch, checkbox		bindchange

Personal experience: It is suitable for selecting true and false in a single item. It is not recommended to use the checkbox style

This is suitable for selecting true and false for a single item. It is not recommended to use the checkbox style. Because the checkbox control already exists. Moreover, when using the checkbox style, there is no following text. The text on the picture is pieced together by me, and no control events have been added (it should not be used this way)
