Installation

pnpm dlx shadcn@latest add https://neobrutalism.com/r/switch.json

Usage

usage.tsx
import { Switch } from "@/components/ui/switch"<Switch aria-label="Enable notifications" />
  • For toggling a setting between on and off.
  • When a compact control is preferable to a checkbox for an immediate setting change.
  • When you need a small or default-sized switch that follows the app’s theme colors.

Examples

Labeled setting

Use a visible label alongside the switch.

labeled-setting.tsx
import { Switch } from "@/components/ui/switch"<label className="flex items-center gap-2">  <Switch aria-label="Enable notifications" />  Enable notifications</label>

Small switch

Use the small size for a compact settings row.

small-switch.tsx
import { Switch } from "@/components/ui/switch"<Switch size="sm" aria-label="Enable compact mode" />

Controlled switch

Use Base UI Root props to control the checked state.

controlled-switch.tsx
import { useState } from "react"import { Switch } from "@/components/ui/switch"function NotificationsSwitch() {  const [checked, setChecked] = useState(false)  return (    <Switch      aria-label="Enable notifications"      checked={checked}      onCheckedChange={setChecked}    />  )}

API reference

PropTypeDefaultDescription
size"sm" | "default""default"Selects the switch dimensions and the corresponding thumb size and checked-state translation.
classNamestring—A class string merged with the switch root’s built-in classes.
Root propsSwitchPrimitive.Root.Props—The remaining props are forwarded to Base UI’s Switch Root. This includes its standard switch props, such as checked, defaultChecked, disabled, and event handlers.

Accessibility

  • The Base UI Switch Root provides switch semantics; provide an accessible name with an associated visible label or an aria-label.
  • Keyboard focus receives a visible outline through the focus-visible styles.
  • Disabled switches display a not-allowed cursor and reduced opacity; pass the Base UI disabled prop to disable the control.
  • The root includes aria-invalid styling for invalid states; provide the relevant accessibility state and validation messaging when needed.
