It's late and I should have gone to bed already, but I stayed to surf.
I think the switches I bought in the US are Chinese (of course since they were cheap) but that the clones are from one brand called Carling Technology V-Series Contura II & III. As far as I can see, the original is not cheap. I'll have a pair of brackets in case the breakers get the better of me.
The relay and the fuse book, I stumbled upon module construction, there are many nice things we can buy. I am happy with the one I bought which is supposed to have six circuits, it is well thought out. Found out that it is pretty much waterproof...
In my youth, 17-18, I went to high school, car electrician, I sat for the trade test when I was eighteen and failed, my only fail. I wasn't good at everything in the field, including starter motors and batteries, but I was good at dynamo, voltage drop and wiring.
So some of my old life comes back again.
I became a professional when I was 20, in the car industry just a little differently, but ended up working mainly as a car painter.
25 then I was burnt out by the industry, we had ups and downs, we had jobs, then unemployed, a couple of times a year, so I gave up working with cars.
Took three more at school and came out with car, machine, construction techniques, the step under engineer.
That was my backstory from my youth.
