How to Use Toggle Properly

Toggle is a simple user interface control that allows users to update preferences, settings, and other types of information. It is also a preferred control for changing system settings on mobile devices since it takes up less screen real estate than two radio buttons. It is important to know when and how to use toggles correctly so that they do not confuse users. To do this, keep in mind that toggles should only be used when they are able to achieve immediate results and provide clear visual signifiers of their current state. They should also be accompanied by clear and direct labels.

The word “toggle” originates from the 18th century and refers to a pin passed transversely through an eye or loop in a chain or rope to temporarily bind it. Today it’s mostly used in software and systems where a toggle is a form of binary or “on-off” command, like the Caps Lock or Num Lock key on a keyboard. A toggle switch in the form of a button or lever is usually used for the same purpose, though it can be any type of switch that allows for on and off states. Toggle is the ideal user interface control for switching between different states of a function or setting. It can be found in all sorts of apps, from the options menu to the download button.

When a feature is being implemented it’s sometimes necessary to use a toggle to test its impact on the user experience. A toggle is a useful tool because it can allow you to compare two code paths in a small cohort of users. Then, if one of the code paths performs better it can be implemented as a permanent change using a standard product release mechanism such as Champagne Brunch or Canary Release.

When implementing a toggle you must consider its longevity as well as the size of its scope. It’s important to keep in mind that a toggle should not be longer than a week or two since it will only reach a small group of users. It’s also good to remember that toggle configuration lives side-by-side in source code, which means it is easy to make changes to a specific toggle without impacting other users who may have been affected by the previous configuration.
