Here’s how to create buttons that click on and click off like a light switch.
Select the button in the work area
Click on the button (1) in the work area to select it. This will show the button’s properties in the Proerty Editor (2) on the right.
Click on Group Index property and type in -1
The Group Index puts buttons in interlocked groups so if one button is pressed the others are released. If you have one button on it’s own and you want it to latch just set the Group Index to -1.
Done!
