Quiet Touch
Provided by the ASK Keyboard Dictionary
Quiet Touch is an IBM, Lexmark and Unicomp marketing term for a rubber dome over membrane key-switch used to contrast it with "Classic Touch" key-switches such as buckling springs (any implementation). As such, the term was typically used only when the host keyboard had a choice of key-switch or the host keyboard directly placed a keyboard with a louder key-switch. The term was typically referring to their own 'simple' rubber dome implementations, but it was sometimes used to refer to IBM buckling sleeves and Micro Switch ST series key-switches.
