Float switch question

[Jim Reynolds]

I am going to build a sump and would like to put in a float switch. My
question is: Do most people use a relay with the
float switch to control the pump or is there a 110v float switch available ?

Thanks,
jmr

I know there is a 110v one on http://www.mcmaster.com/.

John,
Thanks, I will take a look at this.

I am using an Utralife Reef Products float switch. It is hooked up to a
little giant pump for rapid top offs of my 120 gallon setup. Its been set up
this way for 2 years without any problems.

Don't just check voltage. Be sure to check the wattage of the switch
and that it matches up with the pump you are attaching. I use the
following to drive a small powerhead. I replace the small metal piece
with a tie off and it works fine.

It is common for motors to have "inrush current" (startup amperages) in the
area of 6 times the rated amperage. Large pumps will likely have to have a
relay to deal with this. It is also likely a cheaper way to meet the
required amperage for the large pumps.

I used a simple 12v relay. I didn't want to put 120v that close to the
water.

Also, nice story for the usefulness of relays :)

I used to have a 150g and the built in overflows got clogged when I was
away, so, of course the tank couldn't drain as fast as the pump was pumping
and it had endless supply of top off water (RO unit fed top off tank). This
caused a flood in my living room :(
Not wanting this to ever happen again. I buillt a second float switch in the
tank with a smart relay (once it's flipped it stays flipped). so if the
water level got to high it shut off the main pump until it was manually
switched back :)
