Use Boolean controls and indicators located on the Boolean subpalettes to enter and display Boolean (TRUE/FALSE) values with objects such as buttons, switches, and LED lights. Boolean controls have a configurable mechanical action that defines how user interaction toggles the control.

The following list describes the common use cases of Boolean controls and indicators on the Controls palettes in LabVIEW.

Note The availability of Boolean controls and indicators might vary depending on the subpalette style you choose.
  • Button—Use as a control to select a command by depressing the button.
  • Rocker—Toggle—Switch—Use as a control. Select a command by rocking, toggling, or switching the object from one position to the other.
  • LED—Use as an indicator. Display that a condition is met. LabVIEW turns the light ON or OFF depending on whether the condition is met.
  • Radio buttons—Use as a control. Select a command from a list of choices.
  • Checkbox—Use as a control. Select a TRUE or FALSE state, such as when only one option is possible.
  • Mixed checkboxes—(System palette only) Use as a control. Select a TRUE, FALSE, or MIXED state, such as when simultaneously setting a property of multiple objects where some are TRUE and FALSE.
