Thank you. Your answer doesn't have to be specific to an aircraft, however, the aircraft is the Cessna Longitude Citation.
The switch I'm using is a single press button providing keypresses. I have tried 3 options: 1. Preset only, 2. Preset and Input Event, and 3. Input Event only. The only option that worked was #3 without the offset modifier.
My problem, is I want first press on and second press off. The example in my post (without the preset) works to turn the event on but not off.
In addition, I am trying to use the offset modifier technique to use a rocker switch (as on the Alpha and Bravo) with a simconnect toggle event. Push top on, push bottom off.
