Usage

Link to “Usage”

Switches are similar to checkboxes, and can be unselected or selected.

<md-switch></md-switch>
<md-switch selected></md-switch>

Icons

Link to “Icons”

Icons can be used to visually emphasize the switch's selected state. Switches can choose to display both icons or only selected icons.

<md-switch icons></md-switch>
<md-switch icons selected></md-switch>

<md-switch icons show-only-selected-icon></md-switch>
<md-switch icons show-only-selected-icon selected></md-switch>

Label

Link to “Label”

Associate a label with a switch using the <label> element.

<label>
  Wi-Fi
  <md-switch selected></md-switch>
</label>

<label for="switch">Bluetooth</label>
<md-switch id="switch"></md-switch>

Accessibility

Link to “Accessibility”

Add an aria-label attribute to switches without labels or switches whose labels need to be more descriptive.

<md-switch aria-label="Lights"></md-switch>

<label>
  All
  <md-switch aria-label="All notifications"></md-switch>
</label>

bookmark
switches are not automatically labelled by <label> elements and always need an aria-label. See b/294081528.
