Slider switch pin layout confusion SOLVED
« on: January 19, 2016, 11:29:15 AM »
Hi.

Im modding a CryBaby clone using ideas from both
Stinkfoot: http://stinkfoot.se/archives/557
Electrosmash: http://www.electrosmash.com/crybaby-gcb-95
and draco05:

In the picture from draco05' post on "the site that must not be named", he has done a variable sweep range via 3 caps on an on-on-on slider switch. Caps in parallel.
I want to do the same but the switch I have ordered have a different connection pattern
https://www.banzaimusic.com/3-positions-Slider-Switch-DP3T.html

It has a center pin and 3 seperate outputs like a rotary switch.
Let the left pin of the front row be pin 1 and the right pin be pin 4. Pin 3 are the center pin.
With slider to the left, pin1 and 3 are shorted.
With slider in middle, pin 2 and 3 are shorted.
With slider to the right, pin 3 and 4 are shorted.

My question: Is it possible to wire my switch for parallel like the one on draco05' picture?

The reason I ask is that Ive already bought the caps for parallel switching and a new order will cost $9 in shipping alone.

Thanks
Nordskov

Looking at the layout  you have included I think their  switch is left:1-2, middle:2-3, right:3-4   (a design that used to drive me crazy when I was a kid wrecking japanese radios for switches).   

If the operation of your switch matches the C&K  SS-23E05-G, and you turn yours around so that you have pins:1 234   (space is the gap) then  pin 2 is the 'wiper':  slide to the left:1-2, middle:2-3, right:2-4.


For using the switch you have, my solution is clumsy, but should do what you want (the switch is shown pins toward you, and gap towards the left).

good luck,

david

Hi greaser_au.

Your solution seems to nail the problem, clumsy or not, I couldnt have done it better.
So you let the 5.6uF be in the circuit and switch 3.9 and 4.7 in as needed.
Excellent :)

Thanks

That's what the original diagram did, but it isn't arranged clearly (the orange incoming wire is connected to the brown incoming wire by the 5.6 directly).  the values shown are 1: 5.6+ 3.9,    2: 5.6+4.7,  and 3: 5.6+3.9+4.7.

that was fun, thanks!
