HI

I want setup a button like SPST in Labview...where the logic is something like A or B else C. Can anyone help?

Your question doesn't really make sense. A SPST switch is either on or off - there's no in-between state (excluding physical effects like arcing, etc). Further, it cannot have an "else C" state.

I'd normally ask if this is a homework question, but your previous posts don't indicate that it would be, so could it be an issue of no hardware experience?

Hello

Sorry for the confusion. This is not a Home work questions. What I am trying to do is use only ONE boolean button to do following three actions:

Press the button once: State On (~500 msecs)

Press the button again: State Off ( ~500 msecs)

Else: Nothing happens

Right now my code looks like this:

 

 What I would like to do is just one button to do this logic.

I hope this is little bit more clear.

If you use a latch button and a while loop you could do this easily with a shift register to remember the previous state, but I don't see any timing in your VI. You could also do it with a switch button by using an event structure (see attached example).
