Kill Switch?

There's a scene in Father Ted where the priests are all on a plane and Father Dougall is shown into the cockpit, and there's a big red switch with a sign above it that says DO NOT TOUCH and you just know he's going to press it....
This is my Father Dougall moment.
This switch is in the room outside our office. It's currently an unoccupied room, though there are some electrical things plugged in to other switches and power points elsewhere in the room. No one knows what this switch does. No one knows if it's important. No one knows what will happen if anyone switches it off.............my hand is hovering...........
