I've been selecting parts to upgrade a pair of Advents. In the process,
I discovered I didn't know the difference between ON-NONE-ON and
ON-OFF-ON. Duh...

The use of "none" in the descriptions of toggle switches seems to be a
new thing.
Google tells me that several makers are doing it but not when it was they
conspired to do so.
My Farnell catalogue (about 2 years old) has no such "none" sense in it.

I discovered my seeming ignorance when I read a catalog page that treated
all double-throw switches as if they had /three/ positions. Those
/without/ a center position received the NONE description.


I have not come across this, and it seems to me to be about the most
stupidly dopey change of spec for a component that could possibly have been
brought in. Why change what properly describes the poles and action of
toggles switches, and what everyone has perfectly understood for probably a
hundred years ?
