I got a 12 volt relay from radio shack. here is the data sheet http://datasheet.octopart.com/R40-11D2-12-NTE-Electronics-datasheet-55584.pdf
I am trying to figure out if this relay could generate AC (I understand the frequency would be limited to the relay's switch time. )
essentially I am trying to make a H-bridge.
I don't know if the data sheet says but this relay has 2, three pole switches
(I think it is double pole double throw)
thank you for your help.
