The two buttons to open and close each switch are another interesting feature that looks strange from an English point of view.

The 0 and 1 markings have been added alongside ON and OFF to many of our switches and breakers though.

I've also seen Ein and Aus used on German radio equipment, and it interesting that ein also means "one."

Tex,
Does ein by itself also mean "in" as well as "one" or "a/an" ? I'm thinking of Eingang and Ausgang for entrance and exit, so I assume that Aus also means "out"? Or am I hopelessly confused?! [Linked Image]
