Thread: Technical: a switch opening and closing

I'm having a problem with the Russian terms for saying that a switch "opens" or "closes" in certain situations. A Google search on "выключатель закрывается" does not find any meaningful hits, so I'm wondering if the terms "открывать" and "закрывать" are used to describe the functions of a switch. Does anyone have any thoughts about this? What are the proper verbs to use when describing a switch opening or closing?

выключатель замыкается (closing) / выключатель размыкается (opening)

If you mean switch in electrotechnology, you'd better to use "ключ" instead of "выключатель": ключ замыкается/размыкается.
