SparkFun Electronics sells a missile switch cover
“…The hot red safety cover protects a toggle switch from accidentally being turned on. When flipped up, the user has full access to a switch underneath. Upon closing the cover, the cover will force the switch arm back into the lower position – a safety mechanism so you can quickly hit the cover down and deactivate the switch.” (It’s also available in Carbon Fiber)
What a neat idea. There are few things that can ruin your day like
accidentally firing a missle. That queezy sensation you get as
you watch the smoke trail spire into the heavens punctuated by
an involuntary “D’oh!”..
