They lift up over a gate and you move them down to shut off, rather than turning. There’s no guard over them though. They’re not really close to any other switches you’d be manipulating at any time, especially right after takeoff, and they are a different shape than any other switch (Boeing likes to shape their switches differently so that if you grab the wrong one you’ll feel it). I cannot imagine how one could accidentally move one, let alone both switches do cutoff. But sometimes my brain does inexplicably dumb shit, so I dunno.
Oh, ya, ok. Those guards are really more to stop you whacking the side of the switches and breaking the plastic lens and lightbulbs in the top of the switch, but because the switches move up and down and not side to side, those brackets really have no impact on the actual moving of the switches, accidental or otherwise.
