Secret Passageway Switch
Use to activate a secret passageway (or turn on a lamp). When placed in a bookshelf, this electrical switch uses your favorite hard-bound book, without damaging it, to conceal its true function. Lamp not included.
The installation instructions can be found here: http://blightdesign.com/misc_book_instructions.html
NOTE: There will be a 10 day lead time, after payment, before the switch is shipped.
