Editing SMK second generation (section)

==Identity==
The official series name remains a mystery. The name "second generation" was selected to differentiate it from the [[SMK J-M0404 series]] switch. So-called "second generation" switches appear to have been introduced as early as 1986 (with the tactile [[SMK Alps mount|Alps mount]] in the [[Apple Desktop Bus Keyboard]]), and J-M0404 series has been found as late as 1984.<ref name="Wouter" /> No other SMK metal contact switches are known to exist, but the possibility remains that other metal contact switches could have been made before J-M0404 series or between J-M0404 series and "second generation" switches. US patent US4866228 A was filed in 1987, after these switches were introduced.
