Switch

Design System - Switch component

The Switch component is used to toggle between two binary states, such as On/Off, Enable/Disable, or Active/Inactive. It offers a direct, easy-to-understand interaction and provides instant feedback. The design ensures accessibility, responsiveness, and consistency across applications.

Component React

// Sample code
<Switch
  isLabelFirst={true}
  label="Enable notifications"
  shapeOnOff={true}
  isCheckedInitially={false}
  onToggle={(state) => console.log("Switch is now:", state)}
  className=""
  style={}
  disable={false}
/>

Anatomy

Variants

---

	Default This is a clean toggle without any accompanying label or icon. It's compact and ideal for minimal layouts where the switch’s meaning is already clear from context.
	With Symbol This variant includes a symbol (like "|" for On and "◯" for Off) inside the switch thumb. It enhances visual clarity and is useful when colour alone isn't enough to indicate the switch's state.

---

Properties

With Icon An optional icon can be added to the left or right (dismiss/close icon). This enhances usability and improves scanability, especially for chips used in status indicators or filters.

Property Configuration Table

Each design component offers a range of configurable options. These options are intentionally platform-agnostic, allowing implementations to adapt and tailor them to align with the specific requirements of the chosen framework.

React

Property	Value	Default
isLabelFirst	text
label	text
shapeOnOff	yes/no	no
isCheckedInitially	yes/no	no
onToggle	number
className	yes/no
style	yes/no	no
disable	yes/no	no
switchStyle	yes/no	no

Behaviours

	Label Use switches to represent binary on/off states. They are ideal for toggling settings or features that require immediate activation or deactivation. Avoid using switches to indicate errors. Switches are not designed for error states.
	Label Alignment The placement of the label can be customised to appear left or right of the switch. This helps maintain visual balance depending on layout needs and reading flow.

Usage Guide

	Use dividers for activation states Use switches to represent binary on/off states. They are ideal for toggling settings or features that require immediate activation or deactivation. Avoid using switches to indicate errors. Switches are not designed for error states.
