That is basically an "intelligent" vsr, . It would be a good choice. It would be wired as I have shown for a vsr in # 53.
If you feel persuaded by the arguments in favour of a12both switch that could be used in place of the two separate switches.

Your sketch, depicting 2 separate switches make no sense.
I've already posted proper schematics showing how to wire the VSR, with a 1-2-B switch, or with separate switches.
Your fag packet sketch shows that each separate switch switches one battery or the other, to supply power to the engine and the domestic circuits and there is no "emergency" switch. Why on Earth would the OP fit such an abomination ? He's better off with the existing 1-2-B switch, it does the exact same things as your sketch, but has an emergency setting and involves no cost, work or changes. If the OP were to swap the 1-2-B switch for separate switches, it makes sense to have each switch perform a dedicated purpose and to fit the 3rd, "emergency" switch as depicted in my schematic.
Once again, you've tried to reinvent the wheel and just confuse matters.

Go away let those do what they are happy with, why insist they follow you??????????????????????????

I've already said, you can do whatever you you like, i could care less. I've not insisted that anyone follows me. I've posted some suggestions for the OP, including sitcking with his 1-2-B switch, fitting separate switches and three different split charging solutions, so how's that insisting that he "follows me" ?

Jesus. Are you still following this thread even though you clearly have no interest in it?

It might make no sense to you but I am sure it will make sense to anyone with a little understanding of simple electrical circuits and the ability to read a simple circuit diagram.
I don't call those pictures " proper schematics"
There is nothing wrong with my diagrams, especially compared with your pictures that look as though they've been lifted straight from a kid's book on electricity.
There is no need for an emergency switch in the circuit I show with two switches. Switching both ON serves the same purpose just as switching a 1, 2, both switch to the "both" position does, I thought you might have realised that..
The OP does not have an existing 1, 2 , both switch, at least in the first sentence of #1 he says he has two on/off switches so he would not be swapping a 1,2 , both switch for separate switches . He would be using the existing switches.
More Rainbow insults and garbage.
I'm not reinventing the wheel or confusing matters. I have merely responded to the OP's question with a simple diagram showing how I might do things with just the existing two switches and how the same result could be achieved with a good old 1, 2, both switch, favoured by some
It is you who is confusing things .

It would indeed function in the same way as a 1-2-Both switch, but has the big disadvantage of paralleling a good battery with a flat/faulty battery, which is never a good idea. A proper emergency switch, as shown in PaulRainbow's diagram in post 45, links the load side of the two switches, so that a flat or faulty battery can be isolated.

With a 1, 2, both switch if you have a flat or faulty battery that you don't want to parallel with a good battery you simply just select the good battery, leaving the other isolated.
With two separate switches, rather than a 1, 2, both switch you simply leave the isolator for the faulty battery open and just use good battery..

I doubt anyone with even the most vague notion of battery switching and automatic split charging will make any sense of a system design where separate batteries and separate switches, with a VSR, have all domestic and engine loads connected to one battery, or the other. As for switching them both on in an emergency, how does that go:
"I have a problrem with one of my batteries, i know, i'll parallel the good one with the bad one" What could possibly go wrong ?
See above, what could possibly go wrong ?
As for the "kids" comment, i suspect the people on here who have made use of my diagrams might disagree with your childish comments and everyone else can see them for what they are, childish.
Amidst the chatter form others about 1-2-B switches and the anti VSR vitriol i missed the OPs switching arrangement. But my comments in post #10 still stand, especially in light of the diagram you posted.
My drawing don't cause any confusion, they are all very straightforward and well proven. You concepts are typical of some of the ideas that you dream up and post on here, born of a lack of real World experience and understanding.

Thank you Paul Rainbow for your schematics. I've found them most useful and they've encouraged me to draw my own. But with a pencil! Still working on a good schematic of how my alternator booster interfaces with the engine control panel and the buzzer circuit. ??

It is a simple system that will be familiar to anyone who uses a 1,2, both switch and which anybody with any understanding of simple electrical circuits will be able to understand
I've explained how this works in #71 but an "electrician" should be able to follow such a simple electrical circuit diagram without needing an explanation
You seem to think that the circuits you posted in #18 and # 45, and your version of the circuit with a 1, 2, both switch in #23, have some magical ability to prevent a failed battery being paralleled with a good one.
I have news for you. They don't.
Close the "emergency combine" switch, or set the 1,2,B switch to "both", and they will do just that.
You don't even seem to understand the circuits you've posted yourself.
How pathetic
You keep on harping on about this "real world".
My world is one of heavy electrical and mechanical engineering, working with other engineers and scientists and a substantial manual workforce.
What's your "real" world? The insular world of a one-man-band doing electrical work on small boats ?

It's a foolish design that fails to take advantage of the two switches and the VSR
I can see how it works, i can't see why anyone would want to design and install such a system.
Note your use of the word "ability". My designs have the ability to be able to do several things, things that the 1-2-B switch cannot do. The schematic in #23 isn't a design i would plan and install, it's something that i previously posted for someone who wanted split charging but didn't want to change the 1-2-B switch at that time.
I understand my systems perfectly well, as do the people i install them for. We all understand that one isolates the faulty battery before one switches the emergency switch on. The only person that seems to have difficulty grasping that simple concept is you.
Like i said, lacking real World experience of the subject matter, something you have demonstrated many times on these forums. Googling boat manuals does not constitute real World marine electrical experience.
You also have a complete lack of any clue as to how small businesses operate. We don't sit around all day looking things up on Google and dreaming up bizarre ways to do things. I'm part of the marine industry and have contact with a great many other individuals in the industry, as well as those i can call open when my work requires more than one pair of hands. I also have direct contact channels with major equipment manufacturers within the industry and access to information and training that you won't find on Google.

According to #57, you could well be right Richard, seems like he's going for a VSR, who'd have thought it

This never ends well. Like bashing head against a brick wall, it's nice when you stop.
