Toggle is the word we use to describe something that can be set either on or off. It can also be a piece of hardware that switches between two functions, such as the button on your keyboard that toggles Caps Lock on and off. In software, a toggle is a control that allows you to update preferences and settings. The goal of a toggle is to make these options easy for users to change and deliver immediate results. When using toggles, make sure you have clear labels that describe what will happen when the switch is on. This will help users avoid confusion and ensure that they understand what each switch means. The best toggles look similar to sliders and utilize visual cues, like movement and color.
A toggle is usually a good choice when you want to provide users with the ability to modify system functionality and settings. However, it’s important to remember that this type of control should be used sparingly. Oftentimes it’s better to replace a toggle with a checkbox or other control that provides a more explicit choice.
