Switches toggle the state of a single setting on or off. The switch is useful when we want users to toggle between any value, like iPhone Silent Button, etc. Material UI for React has this component available for us and it is very easy to integrate. We can use the Switch Component in ReactJS using the following approach.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command:

cd foldername

Step 3: After creating the ReactJS application, Install the material-ui modules using the following command:



npm install @material-ui/core

Project Structure: It will look like the following.

Project Structure

App.js: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

Javascript




import React from 'react';
import FormControlLabel from '@material-ui/core/FormControlLabel';
import Switch from '@material-ui/core/Switch';
  
const App = () => {
  
  // Our States
  const [state, setState] = React.useState({status: true});
  
  // Change State Function
  const handleChange = (event) => {
    setState({ ...state, [event.target.name]: event.target.checked });
  };
  
  return (
    <div style={{
      margin: 'auto',
      display: 'block',
      width: 'fit-content'
    }}>
      <h3>How to use Switch Component in ReactJS?</h3>
      <FormControlLabel
        control={
          <Switch
            checked={state.status}
            onChange={handleChange}
            color="primary"
            name="status"
          />
        }
        label="Switch Silent Mode"
      />
    </div>
  );
}
  
export default App;

Step to Run Application: Run the application using the following command from the root directory of the project:
