Quiet Touch
Provided by the ASK Keyboard Dictionary
Aka/also known as: Enhanced Quiet Touch, Easy Touch
"Quiet Touch" is an IBM, Lexmark and Unicomp umbrella term for a non-clicky keyswitch of some kind. It's largely associated with keyboards that use rubber dome over membrane keyswitch designs such as the IBM Basic Keyboard, but it's also been used to refer to other IBM Model M variants with IBM buckling sleeves and IBM Model 1B (Micro Switch ST-series based) keyboards as well. It was used to contrast them with the companies' typical clicky keyboards, for which Lexmark in particular referred to as "Classic Touch" as a counterpart. Sometimes the term also appeared in a keyboard's marketing name, for which IBM has released several different "Quiet Touch Keyboards".
