**Alps SKCL Lock** is a alternate action switch in the first and second generation of the Alps SKCM/SKCL Series.
==== Characteristics ====
The switch follows the general characteristics of the SKCL family, consisting of an upper and lower housing, [[:terminology:contact_module|contact module]], [[:terminology:stem|stem]], and spring. There is a follower arm that moves along a track in the stem to generate a locking action wherein the switch stays depressed until pressed again.
There are three switches in the series, both largely identical aside from contact module and materials:
* SKCLJB - A cream-colored SKCL Lock switch in the first generation.
* No part number - A brown-colored SKCL Lock switch in the first generation manufactured as part of the Gold Star Alps partnership.
* SKCLJC - A gray-colored SKCL Lock switch in the second generation.
Alps SKCL Lock, like all SKCM/SKCL series switches, uses a contact module to register the keypress. This sits in the housing on the side without the LED cutout.
==== Additional Information ====
The switch was likely in production from 1983((http://www.google.com/patents/US4514608)) to at least 1994((Alps 1994 catalog)).
