Switch

Switches toggle a single setting on or off with immediate effect. Use them for binary choices that take effect without a submit action.

The thumb slides smoothly. The track color transitions to indicate the new state.

Keyboard focus

Adds a visible focus ring. Toggled with Space.

Usage guidelines

Switch vs. checkbox

Do

Use a switch for settings that take effect immediately.

Don't

Don't use a switch for form consent — use a checkbox.

Content standards

  • Write labels as the setting name: "Notifications" not "Turn on notifications".
  • Use sentence case. Keep to one line.

Keyboard interactions

KeyInteraction
SpaceToggles between on and off.
TabMoves focus to the next element.

Accessibility

  • Use <input type="checkbox" role="switch">.
  • Associate label via <label>.
  • role="switch" communicates on/off semantics.
  • Disabled uses native disabled attribute.
  • Focus indicators meet 3:1 contrast.

Theming

Switch adapts across brands and modes through tokens. Use the hero switches above.
