That's generally a rocker switches work on devices in America, e.g. guitar amps: the side that is pressed is "on" or selected/enabled. Last time I was in Europe (Portugal), I remember having a lot of difficulty making sense of the light switches, but it was one of those apartments where you have two or three light switches controlling the same fixture, which is always confusing. Still, I think the American light switches are actually pretty good. Maybe one day we will get a Technology Connections video about light switches around the world.
