suiss/ui · Component

Switch

A toggle control that turns a single setting on or off.

Switch is an open-source component from suiss/ui for React, React Native, SwiftUI and Jetpack Compose. The @esuiss/ui CLI copies its source into your project, so you own the code.

Switch wraps the switch primitive of the chosen base and renders the track and thumb together. The thumb stretches while pressed, and the track fills with the primary color when on.

Use a switch for settings that take effect immediately. To select an option in a form that's submitted later, use Checkbox.

Installation

CLI

$ pnpm dlx shadcn@latest add @esuiss/switch

Works in any project with a components.json. See Installation for the one-line registry setup. Or use the suiss/ui CLI:

$ pnpm dlx @esuiss/ui@latest add switch

Manual

  1. Install the dependencies and add the cn helper:
$ pnpm add @base-ui/react
  1. Copy the source into components/ui/switch.tsx:
  1. Update the import paths to match your project.

Usage

import { Switch } 
<Switch

Use defaultChecked for an uncontrolled switch, or checked with onCheckedChange to control it. Wrap the switch and its text in a Label so the text toggles it too.

Examples

Checked

Starts in the on state.

Sizes

Compares the sm and default sizes.

With label

Wraps the switch in a Label so the text names and toggles it.

Disabled

Shows disabled switches in the off and on states.

Invalid

Marks the switch with aria-invalid to show an error state.

API Reference

01

Switch

The switch track and its sliding thumb.

PropTypeDefaultDescription
size"sm" | "default""default"Sets the switch size: default or the smaller sm.

Also accepts the props of the primitive part it wraps.

Accessibility

  • Renders with the switch role and aria-checked.
  • Give it a name with aria-label or by wrapping it in a Label.
  • Space toggles the focused switch.
  • A disabled switch sets aria-disabled and ignores clicks.

Notes

  • Uses data-slot="switch" and data-slot="switch-thumb", plus data-size and the primitive's state attributes.
  • An invalid switch draws a destructive border.
  • A transparent hit area extends around the track to make it easier to tap.
  • The thumb's travel flips in right-to-left layouts.

Switch is a pressable track with a round thumb that slides between the off and on positions. The thumb animates with Reanimated and stretches slightly while pressed. It comes in two sizes, default and sm, and has an invalid state that adds a destructive border.

Use a switch for settings that take effect immediately. For choices that are submitted later, use Checkbox.

Installation

$ pnpm dlx shadcn@latest add @esuiss-rn/switch

See Installation for the components.json setup. Or use the suiss/ui CLI:

$ pnpm dlx @esuiss/ui@latest add switch
$ pnpm dlx @esuiss/ui@latest add switch --platform swift

  1. Update the com.esuiss.ui package names to match your project.

Usage

import { Switch } from "@/components/ui/switch"
<SwitchDemo />

Use defaultChecked for an uncontrolled switch, or checked with onCheckedChange to control it.

A switch has no visible text of its own. Pair it with a Label and link them with accessibilityLabelledBy and the label's nativeID, or set an accessibilityLabel. Give the Label an onPress that toggles the value if the label should be pressable too.

The switch has a hit slop around it, so it is easier to press than its visual size.

Examples

Checked

A switch that starts on.

API Reference

01

Switch

PropTypeDefaultDescription
sizeSwitchSize"default"default or sm.
invalidboolean-Adds a destructive border when not disabled.

Also accepts the props of React.ComponentProps<typeof SwitchPrimitives.Root>.

Accessibility

  • The root has the switch role and reports checked and disabled in its accessibility state, so VoiceOver and TalkBack announce whether it is on.
  • The thumb is hidden from the accessibility tree.
  • Label every switch with accessibilityLabel or accessibilityLabelledBy.
  • The thumb animation follows the system reduce motion setting.

Notes

  • The track uses bg-primary when on and bg-input when off, with opacity-50 when disabled.
  • The thumb uses bg-background, or bg-foreground in dark mode.
  • Light and dark colors follow the system appearance.
