This is an electric puzzle that was shown to one of our electricians at a supply house. I have been told that hundreds of people have tried to solve it to no avail. I have not seen this thing but our guy has explained it to me. If there are any questions I will try to get answers. I have not tried to solve it myself as of yet but I will later.
Here it is,
There are two single conductors connected to a 120V male 2-wire cord cap.
Each wire, the hot and grounded conductor, goes to a different box made of porcelain or something similar and non conductive.
There is a single conductor between the two boxes.
In each box there is a toggle switch and a porcelain light socket with an incandescant lamp.
The toggle switch controls the lamp in the opposite box regardless of the position of the switch in the box with the controlled lamp.
The switch is a mini toggle switch. Don't know if it is SPST, SPDT or DPDT.
Our guy swears it works as described.
Good luck? Let me know what you come up with.
Edited female cord cap to male cord cap.

I added a couple caps and sent dxfs to Scott & Master66. Did you want dimmers with those? I was stuck at work on Emergency Standby until the fireworks were finished. I knew the answer immediately, just not my ECN password for the work computer. Joe
Similar circuits for signaling have appeared in electronics journals for years.
Another variant is to have a multi-way switch in one box signal four different states to lights in the remote box by feeding rectified positive, rectified negative, or straight A.C. down the line. The receiving end then shows lamp A, lamp B, both lamps, or none.
According to the information that I am getting, JoeTestingEngr was correct.
This "puzzle" was presented to one of our guys by Sam Scott of Scott Electric Supply near greensburg PA. Found out today that one of our other guys suggested to Mr. Scott a while ago and was correct also.
