Design me an electronic circuit

I have a couple of switches connected in series with a load. The load remains energized until one of the switches breaks the circuit. The circuit is supplied with 110 Vac or 220 Vac.

I want to add one extra conductor in the circuit, and manipulate the AC electrical signal to generate some sort of identifiable address on this conductor. This address needs to be identified by a separate circuit board, and stored in a mod-bus register.

The last switch may be far away (<500 meters), and there may be more than 20 switches on one circuit.

You could do this with just live and neutral, by using carrier current. How many amps is your load? Does it have to detect multiple switches going open, or just the first one? Do you have to send live full ac voltag Mais
