That is some first rate Appalachia engineering right there.
My only question is, if you are going to go to all of that trouble to run those PVC pipes and strings through the wall, why not just run a WIRE through the wall and put a switch on the other side of the wall? Just wire it as a two way switch so that either switch can make or break the circuit to whatever you are controlling with that switch.
I think this may be some sort of work around to get around an arbitrary policy such as, “employees are prohibited from modifying the electrical system in the buildint in any way”.
