That's very interesting, and especially confusing to anyone with a bit of electronics education. A light switch in a simple circuit needs to close the circuit to allow electricity to flow through the light source.
English is my first language, and yet my wife and I tell each other to “open the blinds” and “close the blinds” with far more frequency than “turn on/off the light” (which is on a timer).
In my language you "close the circuit" and when you do so you "open lights" and vice versa. It's not confusing (to me) since "the circuit" and "lights" (in plural) are different words.
