Feed Back through series circuit
Feed Back through series circuit
(OP)
I am using one series ciruit having no of switches connected in series through two wire cable. I want to take feedback in control room, that which switch is operated, how it can be done? In this case I want use same pair of cable that is used for connection in series circuit.

There are (at least) two solutions; either use two diodes "anti-parallel" instead of a single diode or put a capacitor across the switch/diode part of the circuit. Select the capacitor to be around ten times the cable capacitance. A 100 m (330 ft) cable needs something like a 100 nF capacitor.
