Toggle is a user interface component that helps users update preferences, settings, and other kinds of information. When used effectively, toggles help reduce cognitive load by requiring only a single click or tap to deliver immediate results. However, it’s important to be aware of the potential pitfalls associated with toggle switches and take steps to mitigate those risks. Toggle’s can be confusing for users if they aren’t well designed, so make sure to provide clear labels, standard visual design, and consistent context when using them.

When creating a toggle it’s also essential to consider accessibility and the societal and cultural implications of the color scheme. For example, using green as the “on” state can be confusing for users with red/green color blindness. Additionally, some cultures associate the color red with stop signs or stopping, and so using that color to signal a toggle’s on position can be counterintuitive for some users. It’s generally best to avoid using colors that have a negative association with any societal groups when creating a toggle, and to include state descriptors next to the switch in order to clearly communicate its status.

Once a toggle reaches a certain scale it’s often necessary to migrate its configuration from static files into some kind of centralized store. This allows teams to more easily modify and test their toggles at a more granular level. In many cases this involves implementing some form of admin UI which allows testers, product managers, and system operators to view and manage feature flags at runtime.
