I see, well I remember my father tried to replace a 220V AC plug when I was like 15... A "old" house (1950s...) we had in town (Nantes). Well, let's say my sister had to use an extension cord for her room the few years we spent there. To his credit France 1950's seems to have been quite an anarchy period from an electrical perspective (post-war rebuilding era, people were not picky)... They used anything they had to wire the houses, regardless the colors, even some cloth-insulated wires... We were lucky the house didn't burn. Well some estate agent offered my parents a nice check for the land to build appartements and that house of electrical horror is no more ?
So OK those are big, space-grade switches.
