I found the relay diagram to convert constant positive to pulse, but not for a constant negative to pulse.

I know that I could use 3 relays to (1) reverse polarity (2) constant pos. to pulse (3) reverse polarity again to neg.

There has to be an easier way to accomplish this. Is there a way to rewire the relay above to receive and output neg signals?

Input?

Look at the relay section here or the Maplin Catalogue for latched relays.
