Description

alps.tw Type T8 is an Alps clone switch with appropriate characteristics for the currently unidentified Himake/Hua-Jie Hua-Jie AK-C5/D5:

According to the specifications, C5 is white and D5 is orange, and both are clicky. In this case, the clicky switch is grey instead of white, and the orange switch is linear.

The only known date for T8 is a 1993 Ortek keyboard, and alps.tw Type T5 has also been found in essentially the same keyboard and from the same year. Although the T8 looks to be a newer design, it is either older than T5, or it ran in parallel with T5. Note that the long edge of the slider hole in the upper shell on the opposite side from the mould numbering contains a distinctive cut-out that is also present in type T5.

Hua-Jie are not able to confirm whether the depicted switches are in fact AK-C5.

Variants

Grey

The grey version is clicky. The mould numbering on the lower shell in the example discovered is a match for alps.tw Type OA2, except that the writing is the other way up.[1]

Amber

The amber version is linear; it is known only from a single montage image posted by alps.tw and the source keyboard is unknown. The movable leaf stamping is not quite the same (in particular the spacer indentation is oval instead of square and is offset from the the supporting strip of the movable portion. The mould numbering stamped into the lower shell mould in this example is an exact match for the a lower shell found in a Monterey K110, a keyboard known to use Himake switches.[2] This tie-in suggests that both switch types are from Himake, although it could be shared tooling or a shared supplier.
