I wanted to call this "Flipping the Switch" since that is the action being taken here (and both the word "flip" and "switch" describe the text of this card - so good!), but that doesn't fit alphabetically within the card number slot Laboratory Maniac had. So, I went with the next best thing, which was just mentioning the object being used.
I'm not sure if I templated the rules text correctly, but you get what I did here: you flip your whole turn. Well, except for the end phase, which is crucial to be last since it handles many things like cleaning up damage dealt and ending effects that last only until end of turn.
