closedopenThe classic from every mystery ever, this leather-bound book sits on a shelf inconspicuously. However, pulling on it activates a switch that can be connected to another electrical system, such as a hidden door, or a audio message.



  • “Book” can be easily installed into any existing bookshelf with only three screws (base shown in picture is used as an example)
  • Can be made to virtually any size; standard is 2″ x 6″ x 8″
  • Leather can be customized with burned-in design
  • Switch can be wired as normally-open or -closed
  • Additional features available, such as “knocker” inside book to draw players’ attention
