How to wire float switch?

[Brad Perkins]

240 volt pump so I have 2 hot wires. If I want to wire in float switches. 1 down switch to protect my cistern pump and 2 up switches to power my well pump, how do I do this? For the up switch do I simply splice a float in each leg of the 240 volt circuit? Pics would be great if anybody has some. Thanks!!

Float switch in series with one hot. Have a 2-pole shutoff switch before the float switch.

Here is wiring diagram for a float switch with a relay. If the float switch can handle the amperage of the pump you can just wire one leg directly through the float switch and not use a relay.

Thanks guys. These float switches are the high amp type so I don't need the relay.

Those float switches are available with piggy-back plugs, which I think you could stack up. Outlet on bottom, switch#1, switch#2, and pump plugged in to the stack. I have never worked with them.

I read the fine print on the label when installing today and noticed they said for sewage only. The spec sheet showed it was approved for potable water. Now I'm concerned about these switches. They are centripro a2d23w. Are these not safe?

Sewage probably means a pump down switch and you need a pump up switch.

I have both but the lable read was a pump up... I ordered anther cycle sensor today for dry run protection on my cistern pump so I won't need the pump down anymore. wonder if the raw materials used is the issue.

 

[Valveman]

Same raw materials. They just pay out the nose to get it certified and then you pay out the nose for the same thing with no added safety.

is there a recommended float switch that is reliable and bullet proof?

I have never really heard anyone complain about any particular brand. Six of one, half a dozen of the other.
