A 'voltage regulator' can be based on semiconductors, valves or even things like saturable reactors, e.g. magnetic amplifiers. But I fail see how a mains input selector switch can be regarded as a 'voltage regulator'.
Perhaps I have something to learn here.

That IEC mains voltage input connector is a modification, of course, but IMHO, it's a worthwhile improvement over the original connector.
