The V3 Matcha Green Pro switches are a part of Akko's new V3 Pro product line. To start off, they are now 5-pin switches with dust-proof stems. They both increase the stability of the switch when you are using it. The contact pin is also being upgraded from silver pins to palladium gold pins. The leaf spring is now made of alloy copper instead of phosphor copper. The 50gf actuation force is great for enthusiasts who prefer a heavier spring weight.
