# Interaction >> Switch >> Overview ||10
The Switch is used to toggle a property or feature on or off.
```js script
import { html } from '@mdjs/mdjs-preview';
import '@lion/switch/define-switch';
```
```js preview-story
export const main = () => html``;
```
## When to use
- Toggling the component on or off has an immediate action (no confirmation by the user required).
- The Switch is typically used in setting applications.
- The Switch is not a Checkbox in disguise and can not be used as part of a form.
## Features
- Get or set the checked state (boolean) - `checked` boolean attribute
- Pre-select an option by setting the `checked` boolean attribute
- Get or set the value of the choice - `choiceValue()`
## How to use
### Installation
```bash
npm i --save @lion/switch
```
```js
import { LionSwitch } from '@lion/switch';
// or
import '@lion/switch/define-switch';
```
