temporized circuit

Hello to all !

we need to have the diagram with component list for the follow project :

we have 2 signal :

A - 12 V from a switch

B - 12 V power from battery

A,B connected to a DC converter ... our problem is we can't leave powered on the DC converter all the night so we need to shut down after few minutes (15-20 min can be good )

these are the states :

1) starting from shut down system :

A+B ON : pushing a C switch ( we already have this circuit ) the system will start

2A) if the system is ON, I can shut down from switch C, in this case the DC converter will be powered too and we need to shut down after 15-20 min

2B) system in ON, if I turn off the Switch A, system will be on for 15-20 min, then it will power off the dc converter input from battery

ask me if something is not clear

thank you

Please clear me the following points: 1) Is A comes from another supply source. 2) Do you mean SYSTEM as an unit other than DC converter. 3) In (2A), Will switch C OFF the SYSTEM immediately. 4) Will you power off Daha fazlası
