There is an old way of wiring three way switches. It saves one wire between switches. It does require power source at each switch. That way was used a lot on farm yard lights controlled in more than one place. I doubt it makes code anymore. Basically, you don't have 2 travelers on that method.
We had that too. I think that was a special magnetic switch, and the switch itself needed to be spring loaded, momentary. Two wires from each switch to the magnetic control box, didnt really matter how many switches you had.
It had a bit of complicated box controls to run the magnet, dad got cheap and just used a regular switch when the spring loaded one wore out, 'remember' to flip it back again. You know how that ended.....
