Order Switch Question

[Markus]

I'm doing a 2 in 1 pedal with an ADHD and Muroidea and I have a 3PDT switch pcb to swap the order. Is there a way to incorporate an LED so that you can tell the order of pedals when they're both engaged? If so, how would you go about wiring that? thanks.

You could use a 4PDT switch and use the extra column of lugs to switch an LED (or two).

Is it possible to just run a wire from the positive of the DC through a 4.7K resistor into the anode of an LED and connect the cathode to one of the pins of the 3pdt that sticks up through the switch pcb? That way I don't have to order any more parts? If so, which pin would I use?

 

[Robert]

No, that would interfere with the effects. You'd need an unused set of lugs to switch the LED.

 

[Markus]

So I found that I had an extra 4PDT. What lugs should I solder the LED to?

Think of send A as IN and return A as OUT for your first effect on the 3pdt and then the same applies to your second effect.

If you are going to use this 4pdt, I wouldn’t use a 3pdt order switcher board. I would just manually wire it. Or you can buy a GPCB dedicated 4pdt order switcher board.

I like the way Beavis lays it out, easier to see what's what than GGG, but just for a different perspective of the same thing and a schematic and a few other ideas (translocator, Anderton's):

Got it all set with the 4pdt. Thanks for all the help!
