DC pump float switch

The colours dont match the cable.

Sorry didn’t zoom on pic. Easy to test with continuity as it’s only a No/Nc contact.

I would imagine red should reflect brown?

My thoughts too hence my post above. Not sure if the OP has any continuity testing equipment. Easy enough to wire up and if it works opposite swap red and blue.

You are correct, there is an error in the instructions.
Your assumption of how it should work is also correct.

Since there is a mistake in the instructions, I would suggest you test the float switch yourself to establish which is correct. (I will assume Black is common)

It has 3 wires to give you the choice of "up on" or "down on" If it had two wires you would only have one option.

Cheers Rich,

Thanks for confirming.

The float switches I've used before you just flip the wiring, so not seen 3 wires before.

Cool, I'll give it a test and see which way is on at the top.

Thanks again.

You do get some bad luck with some of your projects!

I would suggest Black and Red will stop the pump when it's low and start when it's high, if it works the opposite way to what you want, then black and blue.

Hi John, your first sentence really made me chuckle, you've noticed. Lol.

Cheers for the reply, I'll test it out and see which way is which.

Cheers.

Lol, that's cool, I'll give it a test and see.
