Wiring a float and relay to protect your ATO pump and more

[gregzz4]

Thanks for the nice feedback

You could always get a power supply rated the same as your valve
My floats are rated @ 500ma, but my power supply is 600ma
Maybe I'll have an issue down the road, but I doubt it
It's not like I'm pumping 120vdc through them

Sure you can use a lighter load relay, such as a 5 amp
It'll save you a few bucks

I chose the larger one due to the heater and powerhead, and wanted all my parts interchangeable
You can even use an automotive relay for the 12vdc stuff, but it cannot be used for a 120vdc circuit
You could connect the wires to it without a socket and screw it to the wall/stand somewhere

There are also less expensive sockets, but they are not surface mount and do not have screw terminals - solder tab socket

I just noticed I linked the wrong 12vdc power supply - I'll have it fixed
I grabbed the box for our router supply by mistake
