What is “big”?
From 1960–1990, most keyboards had discrete “mechanical” switches, because they were competing with typewriters, and the main purpose of a computer was “word processing”. By the early 1990s, there were millions of “mechanical” keyboards being produced every year. Computers marketed to professionals still needed to have high-quality keyboards or they would be avoided.
Early rubber dome switches were not particularly cheap, and their selling point was the lack of sound. These were popular for use in open offices, etc.
At some point, computer vendors figured out that customers cared more about price and CPU speed than they cared about keyboards, and figured out that they could produce very cheap rubber dome keyboards consisting of a couple pieces of mylar with some metal contacts on them, one rubber sheet, a couple pieces of injection molded plastic frame, and a pile of injection molded plastic keycaps which popped into the frame, and thereby dramatically cut their assembly costs.
