I would like to know how can I control pump one float switch using relays. I have three pumps. only one float switch. we want to run two pumps together while float switch is enabled. third pump is stand by. same time pump should run by cyclic 1-2-3, 2-3-1, 3-2-1 like that. anybody have relay circuit diagram for this? if i will add one float switch how will be circuit design?
thank you.
