Switches are the preferred way to adjust 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.

Basic switches

import * as React from 'react';
import Switch from '@mui/material/Switch';

const label = { inputProps: { 'aria-label': 'Switch demo' } };

export default function BasicSwitches() {
  return (
    <div>
      <Switch {...label} defaultChecked />
      <Switch {...label} />
      <Switch {...label} disabled defaultChecked />
      <Switch {...label} disabled />
    </div>
  );
}

Label

You can provide a label to the Switch thanks to the FormControlLabel component.

Label

Required *

Disabled

import * as React from 'react';
import FormGroup from '@mui/material/FormGroup';
import FormControlLabel from '@mui/material/FormControlLabel';
import Switch from '@mui/material/Switch';

export default function SwitchLabels() {
  return (
    <FormGroup>
      <FormControlLabel control={<Switch defaultChecked />} label="Label" />
      <FormControlLabel required control={<Switch />} label="Required" />
      <FormControlLabel disabled control={<Switch />} label="Disabled" />
    </FormGroup>
  );
}

Size

Use the size prop to change the size of the switch.

import * as React from 'react';
import Switch from '@mui/material/Switch';

const label = { inputProps: { 'aria-label': 'Size switch demo' } };

export default function SwitchesSize() {
  return (
    <div>
      <Switch {...label} defaultChecked size="small" />
      <Switch {...label} defaultChecked />
    </div>
  );
}

Color

import * as React from 'react';
import { alpha, styled } from '@mui/material/styles';
import { pink } from '@mui/material/colors';
import Switch from '@mui/material/Switch';

const PinkSwitch = styled(Switch)(({ theme }) => ({
  '& .MuiSwitch-switchBase.Mui-checked': {
    color: pink[600],
    '&:hover': {
      backgroundColor: alpha(pink[600], theme.palette.action.hoverOpacity),
    },
  },
  '& .MuiSwitch-switchBase.Mui-checked + .MuiSwitch-track': {
    backgroundColor: pink[600],
  },
}));

const label = { inputProps: { 'aria-label': 'Color switch demo' } };

export default function ColorSwitches() {
  return (
    <div>
      <Switch {...label} defaultChecked />
      <Switch {...label} defaultChecked color="secondary" />
      <Switch {...label} defaultChecked color="warning" />
      <Switch {...label} defaultChecked color="default" />
      <PinkSwitch {...label} defaultChecked />
    </div>
  );
}

Controlled

You can control the switch with the checked and onChange props:

import * as React from 'react';
import Switch from '@mui/material/Switch';

export default function ControlledSwitches() {
  const [checked, setChecked] = React.useState(true);

  const handleChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setChecked(event.target.checked);
  };

  return (
    <Switch
      checked={checked}
      onChange={handleChange}
      inputProps={{ 'aria-label': 'controlled' }}
    />
  );
}

Switches with FormGroup

FormGroup is a helpful wrapper used to group selection controls components that provides an easier API. However, you are encouraged to use Checkboxes instead if multiple related controls are required. (See: When to use).

Assign responsibility

import * as React from 'react';
import FormLabel from '@mui/material/FormLabel';
import FormControl from '@mui/material/FormControl';
import FormGroup from '@mui/material/FormGroup';
import FormControlLabel from '@mui/material/FormControlLabel';
import FormHelperText from '@mui/material/FormHelperText';
import Switch from '@mui/material/Switch';

export default function SwitchesGroup() {
  const [state, setState] = React.useState({
    gilad: true,
    jason: false,
    antoine: true,
  });

  const handleChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setState({
      ...state,
      [event.target.name]: event.target.checked,
    });
  };

  return (
    <FormControl component="fieldset" variant="standard">
      <FormLabel component="legend">Assign responsibility</FormLabel>
      <FormGroup>
        <FormControlLabel
          control={
            <Switch checked={state.gilad} onChange={handleChange} name="gilad" />
          }
          label="Gilad Gray"
        />
        <FormControlLabel
          control={
            <Switch checked={state.jason} onChange={handleChange} name="jason" />
          }
          label="Jason Killian"
        />
        <FormControlLabel
          control={
            <Switch checked={state.antoine} onChange={handleChange} name="antoine" />
          }
          label="Antoine Llorca"
        />
      </FormGroup>
      <FormHelperText>Be careful</FormHelperText>
    </FormControl>
  );
}

When to use

Checkboxes vs. Switches

Accessibility

It will render an element with the checkbox role not switch role since this role isn't widely supported yet. Please test first if assistive technology of your target audience supports this role properly. Then you can change the role with<Switch inputProps={{ role: 'switch' }}>
All form controls should have labels, and this includes radio buttons, checkboxes, and switches. In most cases, this is done by using the <label> element (FormControlLabel).
When a label can't be used, it's necessary to add an attribute directly to the input component. In this case, you can apply the additional attribute (for example aria-label, aria-labelledby, title) via the inputProps prop.

<Switch value="checkedA" inputProps={{ 'aria-label': 'Switch A' }} />
