latching relay with 2 seperate switches

Hi there, would like some help with the above, I would like a relay design that would give me 12 volt supply that latches on when one 12 volt pulse is received and then switches off when another 12 volt pulse is received. Any help would be appreciated, i did find something that latches on and off with a pulse, but what I want is "on" from one switch pulse and "off" from another switch pulse.Thanks

The circuit above will do just that.  Replace the "momentary switches" with your pulses and the 12vdc output will be what turns the camera on and off.Kevin Pierson

Thanks again, I still have not been clear, the camera needs to run on its own 12 volt supply, completely seperate from the supply giving the pulses, I was thinking more of 12 volt latching relay or relays that could be activated with one pulse and de-activated with another. Hope this all makes sense.Thanks

Then control a third relay off the output of the circuit above.  You would then essentially have a set of dry contacts to work with.Kevin Pierson

you also could just use a single relay. you would need a latching type relay thats has dual coils rather than a single coil.

CK has the answer, and if you hang on, I'll post you back with the Maplin UK part number once I get back to discussing beer with KP and finishing my emails,  'cause it's 11:15,  I've just got back from a 230 mile round trip,  reading up on Spurs' win and having a cup of tea and a ciggie. 

As promised Maplin Electronics, 2Amp rating DPDT latching relay, Maplin part number N38 AW about £3.50

The dual coil latching relay would definately simplify things!  Good call guys.Kevin Pierson
