Secret passageway switches are a necessary component in everyone’s dream library. The room opened by the switch could be anything: a panic room, man cave, or even a parisian bakery (if that’s your thing). This switch in particular, uses the classic “hinged book” as its activator.

Of course, if you don’t have access to a hidden room (not many of us do) you can always use it to switch on your light. Illuminating a room won’t be nearly as awe-inspiring as revealing a secret passageway, but it will at least keep the dream alive.
