Switch

Switches allow users to turn an individual option on or off. They are usually used to activate or deactivate a specific setting.

Example#


<Switch>Low power mode</Switch>
<Switch>Low power mode</Switch>
<Switch>
  Low power mode
</Switch>

Content#


Switches accept children, which are rendered as the label.

Switches are best used for communicating activation (e.g. on/off states), while checkboxes are best used for communicating selection (e.g. multiple table rows). Switches, unlike checkboxes, can't have an error state.

Accessibility#

In certain cases a visible label isn't needed. For example, a Switch located at the top of a panel which toggles the panels options on or off. If a visible label isn't specified, an aria-label must be provided to the Switch for accessibility. If the field is labeled by a separate element, an aria-labelledby prop must be provided using the id of the labeling element instead.

<Switch aria-label="Low power mode" />
<Switch aria-label="Low power mode" />
<Switch aria-label="Low power mode" />

Internationalization#

To internationalize a Switch, a localized label should be passed to the children or aria-label prop. For languages that are read right-to-left (e.g. Hebrew and Arabic), the layout of the switch is automatically flipped.

Value#


Switches are not selected by default. The defaultSelected prop can be used to set the default state (uncontrolled). Alternatively, the isSelected prop can be used to make the selected state controlled.

function Example() {
  let [selected, setSelection] = React.useState(false);

  return (
    <>
      <Switch defaultSelected>Low power mode (uncontrolled)</Switch>

      <Switch isSelected={selected} onChange={setSelection}>
        Low power mode (controlled)
      </Switch>
    </>
  );
}
function Example() {
  let [selected, setSelection] = React.useState(false);

  return (
    <>
      <Switch defaultSelected>
        Low power mode (uncontrolled)
      </Switch>

      <Switch isSelected={selected} onChange={setSelection}>
        Low power mode (controlled)
      </Switch>
    </>
  );
}
function Example() {
  let [
    selected,
    setSelection
  ] = React.useState(
    false
  );

  return (
    <>
      <Switch
        defaultSelected>
        Low power mode
        (uncontrolled)
      </Switch>

      <Switch
        isSelected={
          selected
        }
        onChange={
          setSelection
        }>
        Low power mode
        (controlled)
      </Switch>
    </>
  );
}

Events#


Switches accept a user defined onChange prop, triggered whenever the Switch is pressed. The example below uses onChange to alert the user to changes in state.

function Example() {
  let [selected, setSelection] = React.useState(false);

  return (
    <>
      <Switch onChange={setSelection}>Switch Label</Switch>
      <div>The Switch is on: {selected.toString()}</div>
    </>
  );
}
function Example() {
  let [selected, setSelection] = React.useState(false);

  return (
    <>
      <Switch onChange={setSelection}>Switch Label</Switch>
      <div>The Switch is on: {selected.toString()}</div>
    </>
  );
}
function Example() {
  let [
    selected,
    setSelection
  ] = React.useState(
    false
  );

  return (
    <>
      <Switch
        onChange={
          setSelection
        }>
        Switch Label
      </Switch>
      <div>
        The Switch is on:{' '}
        {selected.toString()}
      </div>
    </>
  );
}
