You know what this is. This is the 3PDT switch nearly all boutique pedals are built upon. It's a triple pole, double throw latching push button/foot switch. It's got solder lugs. It's ready for you.
These are used by some really big builders. If you could handle the cacophony of noodling, you'd likely find one of my switches in your local Guitar Center. And I say that as I guy that worked at Guitar Center and noodled all day.
12mm Mounting hole
Soldering Temperature: 250℃ Max for 3 Seconds.
