Still not clear what you are wanting to do I am afraid, the " turn a switch on" is the first thing that has me confused, how can you turn a switch on? Are you meaning a relay? Next thing that has me a bit puzzled is do you wish the signal to be turned off halfway through a move or when? Is the On state to be for a predefined length of time or is it just when you command it to be off? If the latter how are you going to command this off?
I can tell you that it would just be a do nothing pass signal but that may not be the case as it all depends on what you are wanting to achieve and afraid I am no closer to understanding that
