What kind of switch did you build? I'd like to build it as well
What I did was very specific for my use case, not sure if it will fit yours, you can have a look and decide yourself.
Basically I wanted way to turn on and off my whole system pressing one single button of a remote control. So easy but so difficult to achieve sometimes.
A microcontroller receives the signal from the remote and activates the switch, that is based on a mosfet.
The mosfet open/closes the DC supply of the minidsp.
I also have a motu ultralite mk5 connected exactly the same with an identical mosfet switch. I asked Motu if this could damage the ultralite and they said it was fine, but I did not ask minidsp, so I don’t know if this usage is supported or not.
You can find details on the mosfet switch here:
Hi all, I am working on a way to get my minidsp 2x4HD to turn off when the raspberry pi to which it is connected turns off. The minidsp is powered by a 12V DC wallwart and uses 2.5W according to minidsp specs. Because of safety/insurance reasons, i don't want to do anything on the mains level...

And on the final build here (of course, to just switch on and off the minidsp you dont need such a complicated setup, mine has many other functionalities):
Hi all, I am in the process of drafting and ordering my first PCB ever, and thought i would post it here for suggestions or important deficiencies before sending out to print in China. This is a project I make for fun. I came across recently of that very cool project squeezelite-ESP32 that...

If you finally want to go for it and need help, just let me know, I will be happy to help, but be aware you will need to learn a bit about microcontrollers if you never used them before. good luck
