I love these switches because they sound musical. Switches pulled from new Akko keyboards, I went on a binge collecting the Akko switches, they're excellent, so many good options. The Akko Piano Pro V3 Switches 87 Pack is a high-quality keyboard switch set designed for professionals and enthusiasts alike. Made by the reputable brand Akko, these black switches are built to last and provide a smooth and tactile typing experience. With a model specifically designed for the Akko Piano Pro V3 keyboard, these switches ensure precise and reliable performance. Imported from China, these switches are ideal for those looking to upgrade their keyboard for improved efficiency and comfort. I only have five boxes, so the last person to buy will only get one box.
