Multiple 4PDT/3PDT

[Rushkoff]

Hi all,

I've got a project in the works where I have 3 effects in the one enclosure, all of these effects are using 3PDT switching. I've got a 4PDT switch to swap the order between the first two effects using the diagram below but I want to incorporate the third effect with another switch so that effect 1 & 2's order can be switch and effect 3 can either be BEFORE first the effect or at the end of the chain.

My question really is, how would I add another 4PDT and 3PDT into this diagram?

so you want 5 footstomps? what enclosure are you planning on using?

and also, im on my phone on vacation so i cant draw you a diagram but it seems to me that one 3pdt would suffice for this (or a 4pdt if you want a led as well). just do what you did with first two effects, only treat the two switchable as one unit.

Let's develop this from ground up, OK?
You need two type of wirings: bypass switch and order switch.
How about some nice 80s ASCII graphics?

Let's take this for the bypass using a 3PDT with the middle pole/column for LED switching.
The right one grounds the input of the fx board in bypass and usually is prefered.


     SND         RTN                 SND         RTN          
      ^  CLR/LED  |                   ^  CLR/LED  |            
      |     |     v                   |     |     v            
      O     O     O                   O     O     O            
                                       \                      
                                        \                      
IN --> O     O     O --> OUT    IN --> O  \  O     O --> OUT    
             \                            \  \                
              GND                          \  GND              
      O     O     O                   O     O     O            
      |___________|                   |___________|            


Now to the order switch, again using a 3PDT.
You could also use a 4PDT and use the additional pole/column for LED switching.


        RTN1  RTN2        
     SND1| SND2|          
      ^  |  ^  |          
      |  |  |  |          
      O  \  O  \  O --> OUT
       \  \/    \/        
        \ /\    /\        
IN --> O  /  O  /  O        
        / \___/__          
       /     /   \        
      O     O     O        


If you start with the order switch and have one bypass switch at SND1/RTN1 and a second bypass switch at SND2/RTN2, you get an equivalent to your wiring:


    +---+ +---+
    |FX1| |FX2|
    |   | |   |
    |I O| |I O|
    +---+ +---+
     ^ |   ^ |
     | v   | v
    +---+ +---+
    |S/R| |S/R|
    |Byp| |Byp|
    |I O| |I O|
    +---+ +---+
     ^ |   ^ |
     | v   | v
    +---------+
    |S/R   S/R|
    |         |
IN-->|  order  |-->OUT
    |  switch |
    |         |
    +---------+


Now let's add the third FX:


    +---+ +---+ +---+  
    |FX1| |FX2| |FX3|
    |   | |   | |   |
    |I O| |I O| |I O|  
    +---+ +---+ +---+
     ^ |   ^ |   ^ |
     | v   | v   | v
    +---+ +---+ +---+
    |S/R| |S/R| |S/R|
    |Byp| |Byp| |Byp|
    |I O| |I O| |I O|
    +---+ +---+ +---+
     ^ |   ^ |   ^ |
     | v   | v   | |
    +---------+  | |
    |S/R   S/R|  | |
    |         |  | |
    |  order  |  | |
    |  switch |  | |
    |I O      |  | |
    +---------+  | |
     ^ |         | |
     | v         | v
    +---------------+
    |S/R         S/R|
    |               |
IN-->|     order     |-->OUT
    |     switch    |
    |               |
    +---------------+


The ground wires should be clear.

I'm using Eddystones answer to a 1590DD with 3 3PDT's along the button and two 4PDT toggle switches so there's a ton of space in there. Just to clarify, it's three seperate effects that can be independently switched on, one and two's order can be swapped and the third one can either be at the start of the chain or the end of the chain.

Mmmmm confused. I think I have a grasp on how it's supposed to be wired. I know I'll be swapping between the 4PDT and 3rd 3PDT using the 2nd 4PDT, just unsure if I've got a total grasp where the wires are going  


EDIT : kothoma, thank you so much! I'll get right on that !
