on-on-on switch

[psy]

Hi,
I wonder if I can use a LP toggle switch for split/series/parallel.
2hum_2vol_2tone_3way-w-ssp

Does it do the same like a on-on-on?

Thanks a lot for the info my heroes!

Re: on-on-on switch

Nope. LP style switch won't do it. The middle position on a LP style switch just combines the other two settings.

Can't do it with a push/pull pot either...you need a triple throw switch.

You need a real on/on/on switch....also called a Double Pole/Triple Throw...DP/TT.

Whoa! ... Let's get the proper name going, because electronics supplier's are rather anal about this, and will ship the *wrong part* because you asked for the *wrong part* ... The term triple throw is a misnomer technically.
What you want is a DPDT on/on/on ... in the center position it combines one pole with the upper lug throw on one side , and the other throw with the lower lug on it's side.
Mostswitches connect the right pole to the upper throw, and the left pole to the lower throw these days. Bit don't count on it, a quick check with a meter will show you the convention used by that maker.

Thanks Kent. I thought if the switch had three positions it was called a "triple throw" and if it had only two positions it was called a "double throw".

So a on/on/on switch with three positions that would be used for switching a 4 conductor humbucker to series, single or parallel operation is called a "double pole/double throw"? :smack: That doesn't make sense...but OK.

It sorta does. "Poles" refers to the number of physically isolated switches that are controlled by the handle, so DP means two independent switches.

"Throws" refers to number of contact positions that the "common" terminal can connect to, so DT means you can route the signal to either of two points.

The number of handle positions is yet another specification, that defines switch options.

You can have the "ordinary": on-on, or there's:

on-on-on
on-off-on
(on)-off-(on)
on-off-(on)

Positions in paranthesis refer to spring-loaded temporary positions.

Thats probably more info than anyone wanted.

I see. Thanks!

No, man, see there is no *third throw* there are only two, they are just simultaneously used ... Example a strat 5 way switch is 2poles,3throw, 5 position switch ... the 2 & 4 positions share two throws. Now the switch used in the Fender Hot Rod Tele is 2 poles, 5 throw ... as it has 5 independent throws.
The *regular* DPDT switch is called a ...
DPDT (double pole double throw) on/on switch ...
The one you are referring to is called a ....
DPDT on/on/on switch. One that turns off in the middle is a ...
DPDT on/off/on switch ...
The term throw means the actual number of separate electrical contacts that the pole (common) can connect to.
Most people still know what you are referring to, but you can get shipped the wrong part, especially if the person on the other end of the phone/fax/computer, etc. isn't that familiar with the parts and their common conventions of use. If you don't believe me look up how the switches are listed in an electronis supplier's catalogue like Newark, Digi-Key, etc.
I know it seems a bit picky, but it's true ...

Ya know, one day I'm actually going to read the replies before posting my reply ... :smack:
Right now Artie is saying ...*Is there an echo in here? ....*
Ah, yes the SPDT or DPDT on/off/(on) switch ... otherwise known as the square wave tremolo switch ... :laugh2: :laugh2:
