Its hard to describe, imagine a column made of (say) 8 segments, this is the spine of the book.  Each plastic page is connected to a pair of the segments, so those segments move with respect to the others when the page is turned.  The segments and the page is molded from one peice of plastic.  I've not (yet) taken it apart, but I suspect the switches are simply small PCB's and springy contacts.  Probably not suitable if the pages are of the traditional "bendy" type.
