First-time poster, sorry if this already exists. I didn't find anything in a brief search/scan.

I am wondering if anyone can point me to a contactor that can be operated by 24 v or less DC circuit to provide power to a 110 v AC appliance. What I want to do is use a DC circuit to monitor a flow switch mounted in a pool return line that can provide power to a chemical controller when the switch is closed. I've always used a 120v circuit to operate the contactor. But that is for lighting controls, and emergency stops, not a flow switch tapped into plumbing. Harwill makes a unit for this purpose, but it sends 110 to the switch, and that is what I am trying to avoid. Any suggestions?
