No it doesn't. The switch in the link only has a pair of contacts. Both off on 0 or one or the other on the 1-2 position. It needs 2 levels of contacts to cut both lines.

You should know better than

This one is straight forward to install

First contact is between 1 and 2. The second, 3 and 4. Usually there is a little hidden bar connecting 2 and 4 or 1 and 3 to make the common connection. It can be seen just under the square washer on the screws

This is the correct one.

Any why do you need 8 terminals?

Actually, you do need 6 terminals - two in and one out per line.

Neither of the switches are right - the first one or the one you linked to.

You need 4 terminals for a 2 input, 1 output switch - a piar for Live and a pair for Neutral. The first one is not what I would buy, BUT it would work.

There are 2 pairs with a common connection on one side which makes it 6 connections. 2 inputs grid, 2 inputs inverter and 2 outputs.

read my post (I corrected my post as I forgot to add the output lines before your reply).

This is what it looks inside that switch on each level except for the central cam design

 

[HTF]

The one I linked is correct because since it's made as a change over from factory, the pair of screw connections on the picture right have an internal metal link making it effectively only 3 connections on each level. That is just how it is. Don't believe, your problem. Maybe someone else who understands will step in and confirm.

Thanks guys I think I will go down auto switching, now to find auto switch ,, there's so many, any suggestions very much welcomed.

I think this is the simplest more reliable choice Mains supply to the top, off, center and inverter bottom. Completely fool proof and cheap.

Just looking at this one .easier to mount I think. Would it work,?https://ebay.us/m/X92Kso

It will but since it's automatic, might be more complicated to adapt. The one in the previous post is just 2 inputs and one output with manual switching and can be installed on the breaker panel next to the other circuit breakers.

You must take care to connect the on-board battery charger only to the mains wiring otherwise the inverter will feed it and try to charge the battery when it's supplying the 230v which will lead to a dead battery
