Are you sure?

Well in that drawing yes, current state is fuel pump on buzzer off, if you throw the switch then your turning the fuel pump off and the buzzer on

you are right

how about keeping the 2 switches in series as in your very first picture and use these to switch the coil of a changeover relay, put a 12 v ignition fed feed onto the relay contact feed terminal, put the normally closed to buzzer and normally open to fuel pump?
Maybe you could draw it up as i cant visualise it!

The programme is Microsoft Visio, it's a great programme used for all sorts, it has mechanical symbols, all electrical, plumbing, even garden and kitchen design! I used to use it at work for process mapping on business redesign.

some examples, out kitchen plan, and garage plan. I had a Caterham at the time

What about wiring the buzzer into the courtesy light/door is open switch. As per the headlight is on buzzer..

Immob switch open/off = buzz when open door
Immob switch closed/on = no buzz

You could even use the existing warning buzzer, assuming it has one of course.

Am I being very thick? You seem to be making this over-complicated; the other posters have said it.



If and only if ignition on but immobiliser off, then buzzer.

Common or garden three leg rocker switch:
