Lack of info gets no answer, the relay you need depends on the load you will be switching...

OK you need one with a 9v coil that will switches 110v@20A or more...

Something like this should work, using only the NO pole...

FYI that was just the first hit in Google search, I have no opinion on that relay over the other 1000s of hits in the Ebay search...
