PP Double Ball Float Switch

[alcatoe]

Anyone ever used these before? Am I correct in thinking this serves as 2 float switches in one? I want one switch that will detect low and high levels - hoping this is it. Space saver in sump and DT.

Never seen one of those before but that is pretty cool. I just built my own ATO and probably could have used one of those instead of two separate switches.

Sure looks like it. The two black wires should connect to one float switch while the two read wires connect to the other. My question would be how are the floats configured. In other words, On a rise in water level do the switches close or open. Or, do they work in reverse from each other. Unless you are using them as sensors for a controller, I would want both to open when water level rises. That way the bottom one turns the pump off if the water is high enough and the top one is a safety breaking the entire circuit if by chance the lower one gets hung up.

Usually with that style of switch you can take off the clip and flip the float to change how they work. Up can be either on or off based on float orientation.
