Switch
Switches toggle the state of a single setting on or off.
Introduction
Switches are very commonly used for adjusting settings on mobile. The option that the switch controls, as well as the state it's in, should be made clear from the corresponding inline label.

Component
After installation, you can start building with this component using the following basic elements:
import Switch from '@mui/joy/Switch';
export default function MyApp() {
return <Switch />;
}
Controlled
To create a controlled switch, use the checked
and onChange
props.
Label
When a Switch
is used together with FormControl
and FormLabel
, the switch is labelled automatically. You can also use FormHelperText
to include a description to the switch as well.
An alternative way is to place the Switch
component inside a label element. The Typography
is used in this case to leverage the typography scale from the theme.
CSS variables playground
Play around with all the CSS variables available in the switch component to see how the design changes.
You can use those to customize the component on both the sx
prop and the theme.

Common examples
Fluent UI
Here's how you'd customize Joy UI's Switch to make it look like Microsoft's Fluent UI:
- Unchecked state:
outlined

solid
variant andprimary
color.
iOS
Note how we've used the :active
pseudo-class to replicate the small thumb size increase, which happens when you press and hold the switch.
Accessibility
Here are a few tips to make sure you have an accessible switch component:
The
Switch
will render with thecheckbox
role as opposed toswitch
. This is mainly because the latter isn't widely supported yet. However, if you believe your audience will support it, make sure to test with assistive technology. Use theslotProps
prop to change the role:<Switch slotProps={{ input: { role: 'switch' } }}>
Every form control component should have proper labels. This includes radio buttons, checkboxes, and switches. In most cases, this is done using the
<label>
element.- If a label can't be applied, make sure to add an attribute (e.g.
aria-label
,aria-labelledby
,title
) to the input slot inside theslotProps
prop.
<Switch value="checkedA" slotProps={{ 'aria-label': 'Switch A' }} />
- If a label can't be applied, make sure to add an attribute (e.g.
