Hi,
I need to know whether some circuit is activated (drawing power). I.e. I have a water pump out there in the field and I need visual evidence in my house to see when it is on. Of course I can use DPST relay using one pair of terminals to connect an LED, another - to power the pump 220V circuit. But is there a more simple solution to get the LED on using the same 220V circuit?
