The key binding "CMD UV-26 power switch cover" is not operating the cover in the cockpit. As far as I could see, it's not operating anything else neither.
In addition to this, the cover position looks weird when the power switch is on and the cover is closed. The switch doesn't fit into the upper locking notch and the cover doesn't close properly. Might still be the correct behaviour, but it looks wrong to me when compared to all similar switches in the cockpit.
