Hello from Dan KB7UXE..
I have a control ckt that works well using two relays.
I would like to eliminate the relays and change over to transistors.
I have a 12 V source , < 1amp , I need to sink to ground.
I would like to latch it to ground with a momentary ground.
Then release it with a momentary 12V signal .
Due to the sources, the control parameters are set.
ckt needs to be connect with gnd,, and open with 12V.
any help is really appreciated.
Thank you.

here is a drawing. any suggestions on what to use or better way to do it ? ???
