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.
It's red. Like the engorged lips of mammal in heat.
Super reliable. Well loved by lots of respected builders.
12mm Mounting hole
Soldering Temperature: 250℃ Max for 3 Seconds.
