Hm... sort of. I never managed to get a switch. I ended up disconnecting it. There is conflicting information online, but in the version I had open was flat, as I recall (which is what you would expect). I would still like to put a switch in. There are different versions of the terminal block and switch. I think the big changes occurred around 2011.

I would still like to get a switch (pre-2011 style) if anyone has one
