The porcelain knobs in the wall and associated porcelain fittings (to modern standards) are still available for the authentic look, if you like that sort of thing. The porcelain knobs are designed to hold fabric covered twisted cable, a bit like our old lamp pendants were. The twisted cable, now double insulated and with an extra cable, the earth, is still available as a replica if you want to retain the period look.

I think the plastic Ticino brand switch and the wiring itself is relatively modern, though looks like a bodge to be honest.
If not, scrap the cable and look at ebay or similar for selling the porcelain stuff.
In fairness, I've seen much worse than that over here, and since the Italians consider twin and earth cable ('piattino') for mains wiring to be a relic of ancient history, I think it's fair to say that our wiring and their wiring developed differently, and leave it at that.
