   >>>Is there a way to run a three wire cable from the attic above without damaging the wall around the switch.

   Is it a plastic box or metal?

   >>>but if you're living right you can fish into an existing box.

   Hahaha..... that explains why I've never been able to!!!!!

   Always had to settle for the box-ectomy procedure.

   If it's an interior wall, running a new wire isn't usually as difficult as you perceive.

   Otherwise, there are electronic switches available that can "extend" a circuit either wirelessly or on a limited number of wires.

   Thanks for your advice.  I am not an electrician,but am  an electrical engineer and have done a fair amount of wiring. Unfortunately, your right on with my thinking. Just a tough job.

   I'm an EE as well, and have done my share of 'fishing" wires over the years (not as a pro, but as a homeowner & volunteer).

   So long as there's halfway decent headroom above and no fireblocks in the wall you can fish in a new wire fairly easily.  (However, it is still probably advised to banish small children and any others with sensitive ears from the job site.)  It helps if you have a person on each end, but it can be done solo.

   There was a article about small metal piece on a string and magnet rod from the box.  Also, fishing is easier with fiberglass rod although they cost more.  Hope it helps.
