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...

How about on-on-on .

What does It use ?

I have a tendency to want to eliminate any controls, especially pots, yuk.

After assembling, then dissembling cabinets many times while testing
values, I started to mount the crossover on the outside for one of a kind
speakers !

That would be a DP3T.

DPDT, ON-OFF-ON.

It has no pots. The switch controls the tweeter level.

** 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.

2 states v 3 states, no?

No. Two positions versus three positions for a double-throw toggle.

NONE is for a two-position switch, OFF is for a "double-throw" switch with a
center position in which nothing is connected.

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.

Have any of you ever run across what looks like a double pole double
throw that is actually a one pole three position?



1 T 2T T T T T
l /l /l /
l / l / l /
3 T/ 4T T/ l T/ T
l l l
l l l
5T 6T T T T T

fig 1 fig 2 fig 3

In all figures the hash marks between 3T and 2T represent an outside
shorting connection. The small case l's represent the "wiper" positions.
If you take 4T as the output and 1T,5T and 6T as inputs[or vise versa].
The Sw becomes a 1 pole 3 pos sw.

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 ?

You just don't get it. They must now "interpret" things like the Law and Constitution so everything is up for redefinition. Yes, that means you are all right and the world is all wrong.

Glad to be of help.

Agreed. I think most people understand that ON-ON describes a double-throw
switch with two positions, while ON-OFF-ON describes a double-throw switch
with three positions.

and Constitution so everything is up for redefinition. Yes, that means

Courts have been interpreting the meaning and application of laws for hundreds
of years. This necessarily carries with it the interpretation of
constitutions.

Huh? Assuming a 3 position switch, and that it is impossible to have
a make before break feature in a 3 position switch, the two
designations are identical. What am I missing here?

You're missing the fact that ON-NONE-ON is a two-position switch. When I read
the spec sheet, and saw that ON-NONE-ON was two-position, and ON-OFF-ON was
three-position, for the same switch series, the light finally went on.

I can refer you to spec sheets, if you like.

Why would that be impossible? If the switch have 1 input and 3 outputs.

ON - None - ON simply means the DPDT switch only has TWO positions - ON
& ON with no center spot (OFF). Consider it ON (A circuit) and ON (B
circuit) relative to the commons.

Think of a 3-Way switch as used in house wiring - but with an extra pole
- then it is obvious.

A "3 Way" switch in the wall is an SPDT (the only thing a 3 port
switch can be.)

Sigh. Got it. All the desktop publishing computer jocky that created
the data sheet could have done was to put a big "X" in place of the
"NONE", or possibly left the box blank, and there would not be any
confusion. Extra credit if they had added a column with the number of
positions. In any case, it's not very clear as the designation SPDT
could be 2 or 3 positions. Usually, it's marked SPDT center off, from
which the designer is expected to deduce that this is a 3 position
switch. Argh.

I find it fairly obvious.
What is the connections in the center position?
Answer: "It is OFF" - A 3-position switch, center position OFF
Answer: "It is NONE" - A 2-position switch, there is NO center
position

An X would be less obvious.
Answer: "It is X" - I don't know / Crossed over / ????

At least you will only make this mistake once ;-)

Not to insult you, but are you self-taught, or have you formal
education in electronics, or some sort of apprenticeship? You should
have learned the meaning of switch-nomenclature there.

I remember those old selenium rectifiers, they had a distinct smell if they warmed up during their usage, I remember them being used in car battery chargers in the 1940's.

First solid-state rectifier I remember was a 1N34 that I used in a crystal radio in the 1947-48 time frame.
