CheckBox 
With a CheckBox you can implement a single on/off switch. A checkbox enables the user to select a Boolean value (TRUE/FALSE). The UI element consists of a graphic with text. The checkmark in the box indicates that the option is selected and the value is set to TRUE.

If the properties text and label have not been set, the property tooltip is checked during the design time to ensure Accessibility.
A tooltip does not necessarily have to be set for this UI element, but it could make sense to set it if it contains detailed semantic information.

If you want to offer a group of logically related check boxes, use the UI element CheckBoxGroup.
