No, a key object *itself* is a destination. Sorry for being confusing. The *switch* destination needs to be -> the key object.Hope this helps?The F0, F1 etc are just the example of Dirk's own setup. It is best to start from scratch - the example is a good one for reference, but do your own configuration. The F0 etc are good if you have a flap switch that has certain "detents" like an airliner has. Not needed for "more flap / less flap" switch.//Tuomas

Hi Tuomas,OK, now I understand.I have created key object entered in the sequence you suggested for on action and repeated it for off action. (Called it Key_f7 & f6 as suggested)I then created switch and made the destination fsbus object Key f7 and the other one key f6. Called them Flapup and Flapdown respectively)When I move the switch, I get an action in the switch and in the key object but nothing happens in flight sim.I tried FSInterrogate to locate what was changing but that only confused me more.Any ideas?David
