# Switch

A control for toggling between on and off.

## Import

```tsx
import { Switch } from '@coinbase/cds-web/controls/Switch'
```

## Examples

```jsx live
function SwitchDemo() {
  const [checked, setChecked] = useState(false);

  return (
    <Switch onChange={() => setChecked((s) => !s)} checked={checked}>
      Dark Mode
    </Switch>
  );
}
```

### Customizing Colors

Like other control components (i.e. Radio, Checkbox), you can customize the color of the Switch by setting the `controlColor` prop.

```jsx live
function SwitchDemo() {
  const [checked, setChecked] = useState(false);

  return (
    <Switch controlColor="accentBoldGreen" onChange={() => setChecked((s) => !s)} checked={checked}>
      Custom control color
    </Switch>
  );
}
```

For more advanced color customization, you can use additional style props like `background`, `borderColor`, `borderWidth`, and `color`:

```jsx live
function AdvancedSwitchDemo() {
  const [checked, setChecked] = useState(false);

  return (
    <Switch
      background={checked ? 'accentBoldPurple' : 'bgNegative'}
      borderColor={checked ? 'bgPositive' : 'bgPrimary'}
      borderWidth={200}
      checked={checked}
      color="bgPrimary"
      controlColor="bgPositive"
      onChange={() => setChecked((s) => !s)}
    >
      Advanced styling
    </Switch>
  );
}
```
