I need some help in deconstructing the following ( please see photos of upstairs downstairs switches ) as I don't know what the circuit diagram would look like in this case?
It works perfectly well
Is seems to be a shared neutral circuit but does not follow the normal convention as shown in the diagram.
As the cabling is inaccessable I cannot trace the route.
Is this a known standard 1960's circuit
