A toggle is a control that is used to quickly switch between two possible states. It is most often used for “on/off” switches. In contrast to checkboxes and radio buttons, toggles don’t rely on color alone to convey meaning. Instead, they use a visual design that reflects the current state of the toggle. They are also usually designed to have a clear and concise label that communicates what action the toggle performs, and the underlying state of the element it controls.

A common use case for Toggles is when they are used to implement Multivariate Testing or A/B testing in a product. With this technique a feature can be exposed to multiple cohorts and the performance of each can then be measured against one another. This can be used to drive significant improvements in user experience, conversion and other business metrics.

Toggles can be very useful in these situations, as they make it easy to experiment with new features. However, it’s important to ensure that they are well-designed and consistent with existing design patterns. In addition, it is important to clearly identify the setting, view or content that a toggle controls. This helps users understand what effect their actions will have and allows them to make informed decisions about their preferences. If the toggle is not intuitive, it will be difficult for users to learn how to use it effectively. This can be especially problematic if the toggle is hidden or obscured from view.
