that is sorta the circut, there is bits missing im sure,
basicaly i need it to latch when 3v is applied, then unlatch by a button
also i need it to stay latched if 12v is disconnected, or stay unlatched (memory sorta thing)
any help is much appreciated

and the relay needs to stay switched when the volts are removed, untill another switch is pressed (momentary switch).
i built a circut using a transistor, a...
