# Switch

Change a boolean setting.

## Public import

```svelte
<script lang="ts">
  import { Switch } from "rom-studio/controls";
  import "rom-studio/styles";
</script>
```

## Composition and responsibility

The host supplies data, callbacks and application policy. The component does not provide persistence or authorization.

Public names: `Switch`.

## Declared props

This declaration comes from the installed package. Imported types retain their upstream meaning.

```ts
type Props = WithoutChildrenOrChild<SwitchPrimitive.RootProps> & {
		size?: "sm" | "default";
	};
```
