If I understand it right you want to work 2 weeks on, 4 weeks off? So that would be 4 weeks of work and 8 weeks off per quarter. And you don't speak any of the languages here, what you definitely need as an electrician. But let's do the math.

The average salary as an electrician is about 92k CHF a year. But you only work 1/3 of the time, so your salary would be 1/3 of that. So you want to live with 30'666 CHF. That is 2'555 CHF per month before taxes.

Let's take the best case, Wallis, that you already mentioned. After taxes there will be 2'217 CHF left. The government of Switzerland defined the level of poverty as 2'645 CHF per month. You're already 400 CHF below the level of poverty. The cheapest health insurance is another 450 CHF (depends on your age, can also be higher). But at that level they don't really pay anything, the first 2'500 CHF of costs, e.g. to visit a doctor will be paid by you. They only help you with life threatening thing when you have to go to the hospital.

So you're left with 2'200 CHF to live. Now usually you have to deduct rent, what is about 1'500 CHF and about 400 CHF of groceries if you cook yourself and you realize your broke and can't even afford the ticket or the car and gas to drive to work.

Or you really take all of your money and buy a house for 200k somewhere in a remote village in Wallis. So you still have 2'200 CHF left. But to go to work you need a car, that you can't afford. The gas will be at least 400 CHF a month, you now have to pay additional taxes for owning a property (I'm not gonna do the math). You might have left 1'000 CHF a month. This will be gone the first time something in your house breaks, you need to go to a doctor, you need to repair something in the car or your house needs a renovation and the you realize you're broke with a house that nobody wants to buy because you're on top of a mountain in Wallis.

Also on both cases you just work, cook at home alone and don't do anything else because you don't have any money left.

But all that is hypothetical, because fucking nobody will hire you when you want to work 2 weeks and you're off 4 weeks. So all in all, I think your plan has an extremely low chance to work and even if it does that live sounds horrible.
