I'm experimenting with a modified Fuzz Face circuit and I'd like to have a 3 way switch that goes between 2 capacitor values plus an off position that acts as if there was no connection. This will be placed across the Base and Collector of Q1 as a 2 position LPF and no LPF. Would this be the correct switch to use and if so, how would I wire it to achieve the result I'm after?
3 way switch for 2 different capacitor values plus off position

From the same thread. Most DPDT are type 2, but always check.
No, the second example is basically an or switch, no series or parallel. 1 2 or 3.
This is nice because you get

Like a lot of lazy/cheap commercial builders do to save 59 pesos on a 2 pole switch
If you don't populate C1, it's an open.l to ground .Wire in place of C1 and it's a short to ground.
The first example uses series caps.
I'm confused. What is meant by "TOGGLE UP sums parallel C2 & C3" here? Or am I looking at the wrong diagram?
Also, I'm looking at the datasheet for these and I don't see a diagram or notation that specifies whether it's type 1 or 2. Man this stuff is confusing for a beginner!

Bear with me a moment...
When you add resistors in series, like a train hauling boxcars, the resistors add up together; so 10k + 12k = 22k
There is some weird stuff that happens when you stick resistors in parallel, like two pontoons on a catamaran:
10k + 12k = 5k4545.
Two identical values in parallel halve, so 10k + 10k = 5k, but the math (for me) is complicated when using differing values so I use this handy online parallel-resistor calculator https://www.1728.org/resistrs.htm.
NOW, capacitors are the opposite of resistors when it comes to the math.
Parallel caps SUM: so if C2 = 100n and C3 = 56n then C2+C3 in PARALLEL = 156n
Caps in series behave exactly like resistors in parallel, in fact you can use the same 1728 calc link above to determine C2+C3 in series = 35n897
The toggle diagram posted by Jwin615 operates in such a way that with toggle UP both C2 and C3 are in play and since they are parallel you get whatever the two values are added together, simple math, no need for the online calc nor the formula (said formula is posted on the 1728 site if you insist on doing the math yourself for series capacitors).
Also, I'm looking at the datasheet for these and I don't see a diagram or notation that specifies whether it's type 1 or 2. Man this stuff is confusing for a beginner!

The info is there, but it IS rather convoluted.
Normally when we talk about switches we're looking at the bottom of the switch, its lugs, and typically is numbered as top-left down and then back up to the top of the next pole... here a DPDT:
1 — — 4
2 — — 5
3 — — 6
Pole 1 or Pole A being on the left in orange,
and Pole 2 or Pole B on the right in purple.
I prefer to call them Pole A and Pole B because the lugs are numbered and it seems less confusing if you differentiate poles from lugs alphanumerically.
In MY experience MOST DPDT on-on-on are TYPE-1... took me so long to find a TYPE-2 that by the time I did, I'd already pulled apart a Type-1, flipped the widget inside to MAKE IT a Type-2.
The problem with Tayda, as I recall, was they were selling Type-1 switches but since they were looking at them, IIRC, top-down (like an x-ray through the top down to the lugs) and so then called them a Type-2.
At any rate, Tayda or the manufacturer of the switch WHOEVER wrote the damned datasheet has the lug-numbers all screwed up, so it takes some deciphering to determine what's really what, but all the info needed is there...
The above shows you what's connected in each toggle-bat position, with the unintuitive "5-4" instead of 4–5, and "2-1" instead of 1-2...
I mean, look at that
— they're calling a DPDT on-on-on a "SINGLE POLE, 3 POSITION" switch.Look at the numbering! It's not wrong, just ROTATE IT 180º and you've got lug-1 in the upper left corner where it belongs.
What they're calling "DOUBLE POLE" in the above datasheet snippet is actually a 4PDT.
As per Jwin615's post#2 above, first post in the thread and in addition to it:

I'm hoping this thread can be a catch-all for interesting and unconventional ways to use switches, whether rotaries, relays, footswitches, toggles...
Here's one for a starter:
I saw this a long time ago, supposed to be a DPDT "wired as on-on-on" that can act like a3PDT.[EDIT SP3T]
and info collector that I am I DL'd the diagram, thinking it might have some use down the road.
Recently came across it again and thought the diagram is a wee-bit confusing so I fired up DIYLC to make better sense of it:

Therein you'll find an easy-peasy method posted by PauloB:
For a CENTRE-OFF position, just swap the diagonal cap for a jumper.
Here's another level of wizardry posted by Cybercow:
Just remember that the TOGGLE-BAT points to the opposite side of the switch, so if you want small cap when toggle is left, you attach it to the lugs on right as below in orange:
I thought I'd posted a Rangemaster switcheroodoohickie, but I can't find the post...
Voila, still on the confuser's HD:
Yeah, okay. Enough.
