Michael, I believe this is the data you are looking for. 73, Roger WA7BOC K2 #755
"The K3's front panel switches do provide positive tactile feedback, via integral polydomes. The material we selected is rated for extended lifetime (many decades, in this application), and the silver contacts are fully sealed. As for the printed legends, they're protected by a matte silicone hardcoat that's impossible to rub off. In addition to the tactile feedback, we provide visual and audible confirmation of every switch closure. 73, Wayne N6KR" [K3] question to Elecraft staff /Wayne about K3 keytopmfg...
