Getting a job in Switzerland without degree

Hi everyone,

Like a lot of peoples here, I do not have a CS degree but I want to change career as a software engineer.
I am a french citizen currently living in Singapore. I would like to relocate to Switzerland and I was wondering if it is difficult to get a job there without CS degree. I am currently a teacher, by the way.
I do not think it will be easy anyway, but is it at least possible? French peoples tend to need the degree above else. How is it going on in Switzerland regarding the degree?

Thank you all for your answers!
