+**Alps SKCM Ivory** is a damped tactile switch in the second and third generation of the Alps SKCM/SKCL Series.
+==== Naming ====
+This switch has previously been called "Alps SKCM Cream Damped" or "cream damped". It has been renamed here to match the Alps catalog.
+==== Characteristics ====
+The switch follows the general characteristics of the SKCM family, consisting of an upper and lower housing, [[:terminology:contact_module|contact module]], [[:terminology:stem|stem]], spring and a [[:terminology:leaf_spring|leaf spring]] for generating the tactile event.
+SKCM Ivory straddles the second and third generations, and as such can be found with and without slits, though the version with slits is much more common.
+The stem, which is a slightly translucent off-white color, features rubber dampeners that slot into either side of the stem. The lower housing of the switch also has widened stopping points to make connection with the dampers.
+The tactile feedback is generated with a leaf spring that is situated on the opposite side of the housing to the contact module. There are two revisions of the leaf spring.
+Alps SKCM Ivory, like all SKCM/SKCL series switches, uses a contact module to register the keypress. This sits in the housing on the side with visible notches.
+==== Additional Information ====
+SKCM Ivory was introduced in around 1989, and appears to have been produced until 1995. There are two revisions of the tactile leaf spring - the first being the hole-punched type, the same as is found in both [[switch:alps_skcm_orange|SKCM Orange]] and [[switch:alps_skcm_salmon|SKCM Salmon]], and the later type being the "dimple" leaf seen in third-generation [[switch:alps_skcm_black|SKCM Black]] and [[switch:alps_skcm_white_ivory|SKCM White Ivory]].
