So I am making a triple AB switcher

[PaulNYC]

I cannot leave well enough alone. I am building a triple AB switcher to allow me to switch amps and effects loop with a single button press. I only need three AB switches to choose which:
* Amp Input
* FX Loop

To start off I am testing my TQ2-L2-9V double coil latching relay. It's a little different than a single coil relay.

It's my first time playing with a breadboard. Why did I wait so long???

I am planning to do the left two poles of this 3pdt:

Here is my new oscilloscope:


the LEDs are a test of a flyback diode. They didn't light up for me.


I'll update as I get more parts.

Looking at the photos, my anode is not in the circuit ...

I fixed it:

I butchered the paint on the enclosure, but overall a good project.

I made this triple relay board:



and then I atrached it to this board from aliexpress that swithes based off of a momentary switch:


Then I enclosed everything. It works!
