You might notice that each time you run the VI, you must turn on the

vertical switch and then click the Run button in the toolbar. With G, you

can modify the mechanical action of Boolean controls.

There are six possible choices for the mechanical action of a Boolean

control:

• Switch When Pressed

• Switch When Released

• Switch Until Released

• Latch When Pressed

• Latch When Released

• Latch Until Released

Below are figures depicting each of these boolean switches, as well as a

description of each of these mechanical actions.

Switch When Pressed action—Changes the control value each time you

click on the control with the Operating tool. The action is similar to that of

a ceiling light switch, and is not affected by how often the VI reads the

control.

Switch When Released action—Changes the control value only after you

release the mouse button, during a mouse click, within the graphical

boundary of the control. The action is not affected by how often the VI

reads the control. This action is similar to what happens when you click on
