I have a relay that I picked up from Radio Shack a while ago, and now I have a use for it, but I don't have the datasheet, and can't seem to find it online.
The top says GEO 3F-12V3
Below that it says 12VDC, which I'm hoping it's the coil voltage.
Near the bottom it says 15A 125VAC.
It is a SPDT relay, if that helps.
I just don't want to over volt the coil.
