What kind of switches are used on the K3?
The K3 uses full-custom, high-reliability switches selected specifically for their tactile properties and long rated lifetime (typically > 1M operations). They’re fully sealed against moisture, which is important for use in high-humidity environments. Each switch incorporates a large polydome for positive tactile feedback (about .02″ travel), and the contact surfaces are gold-plated. (These are not the hard-to-press, no-feedback matrix switches found on cheap calculators.) The switches are molded into several custom shapes, including two rocker switches (BAND UP/DN and MODE UP/DN). They’re labeled in two different colors, and the ink is protected by a hard-coat that’s also rated for very long life.
