switching order (answered)

[Anonymous]

Trying to figure this out with no luck, I’d like to switch 3 pcbs 1-2-3 to 3-2-1 so I just want to switch the 1st and 3rd boards leaving the middle board as the middle, can I do this with a 4pdt or do I need to go to a 6, my brains not working well today any ideas or solutions

Thanks!!

If you use a 8PDT switch to change all positions at once, this will work.

Thanks, I’ll give it a try

I was trying to figure out a way to use a 4pdt that would leave #2 as a passthrough while switching the 1-3 around it, but all it did was give me a headache, 8pdt makes sense it’s just alot of switch! I appreciate you taking the time!

You are welcome.  I enjoyed the mental challenge of this.  I wonder if anyone else on the forum can come up with a simpler solution?

Wilkie – I saw this post shortly after you posted the drawing you did, and I have to confess, I first thought it was a simple as just extending the 2-circuit switching order concept. But when I looked closer at your response and drawing, my brain started to hurt. Now I need to sit down with a cuppa in the morning and better analyze it and get out my own paper & pencil to actually wrap my head around it. At the moment, I cannot conceive a simpler purely mechanical method. I was initially thinking of a combo of order switching PCBs with 4PDT switches to achieve an “any order” configuration. But I see now that the OP simply wants only to switch circuits #1 & #3. (If I read that correctly.)

It took me a few hours and several cups before I was able to come up with the diagram. I kept thinking there must be a simpler way to do this, but he wants the entire chain of three to be reversed.  An interesting problem.

got the switch and it’s not going to work, there is no way to mount it in the pedal except maybe glue/pray so I’m going to try and find something, it may end up being a double toggle

[wilkie1]

Bummer.  I thought it would fit mounted through the side of the pedal.

Yeah the image was pretty deceiving the round section all moves and holds the spring, other than maybe internally the only way to mount it would be a square hole with a retainer clip but the spacing is smaller than the thickness of a pedal housing
