AC/DC 24V SPST 20Amp 250Vac/30Vdc Latching Relay Module, Plastic Enclosure Wired

With AC/DC 12V clearly listed, you can quickly check it against your current setup.

A nice touch is the3P-210B pin layout, which aligns neatly and prevents guesswork during wiring.

You will find that the relay and socket stay cool under load, helping you trust the build over time.

The relay runs on DC 12V, so it's a good match for battery-backed systems you already have.
