Relay Bypass Module Questions

[himers1990]

Hello.
I want to put effects A and B in one enclosure.
Use one relay bypass module to switch between A and B with one switch, and also do this with a remote switch.
Which relay bypass module should I use to accomplish this?
How do I wire effects A and B and the relay bypass module?
Any suggestions or advice would be greatly appreciated.

maybe you can use 2 latching relay bypass boards like this:


they would have to bet setup with one on and one off and would swap when a switch is activated. They should be non latching two pole switches
***MIGHT WORK*** not sure. There may be a smarter way. You might be able to do it with a single 3pdt switch but no remote switch

So you want to toggle between Effect A and Effect B with a single footswitch?

Do you want to be able to bypass both effects?

I didn't account for a bypass lol prob not the best idea

With bypass:

I think you could do the A/B switch with the DPDT relay module instead of two bypass modules

Thank you everyone!!
If possible, I'd like to be able to switch between A and B with one switch.
If possible, I'd like to know via an LED which effect is active.
I would appreciate your continued suggestions and advice.

Here's a quick drawing. Assuming you do not need bypass, you can use one PedalPCB intelligent relay bypass module like this...
Effects A and B both have the inputs tied together and come from the input of your pedal.
Pedal A output goes to "Jack In."
Pedal B output goes to "Out."
"In" is not connected to anything.
The output of your pedal comes from "Jack Out."
The "SW" controls the LEDs. Two LEDs can be connected to that as shown. You will need a 1n914 as shown to not allow both LEDS to be on at the same time. Sorry for my crappy hand drawing.
Not shown here, you can hook up as many normally open, momentary switches as you want in parallel.
If you also want a bypass, you'll need a different design altogether.

You might need a 2nd 1n914 to make sure LED A does not remain on (dimmly) when it is supposed to be off. Like this. And those can be 1n4148 or 1n4001 or what ever. They are not important values. Might not need the second, newly added diode if the first one is a shotkey.

And, of course, the DPDT module can do this, too. Either one will work, if bypass is not needed. Neither will work if bypass is needed, since that is three separate states. The other switch in the relay could be used to make the LED circuit simpler (no extra diodes needed) if using the DPDT module.

Here it is with the DPDT module instead of the intelligent relay bypass module.

Here it is with the intelligent relay bypass module. Of course, if ordering something, use the DPDT version. This is only if you already have these in hand. I used a schotkey diode to make sure LED A goes fully off.

Will this wiring completely turn off the LEDs of effects that are not selected?
I'm curious about the wiring method.
Is the LED 10kΩ specified?

LEDs will turn off. Input signal is connected to both effects and both effects will be active at all times and sending output to the relay board. The relay board will select one of the two outputs.

10k for the LED is a guess. LEDs vary so much that you should always test yours for desired brightness and hand-choose a resistance.
