alps.tw Type T1 is an Alps clone switch design that corresponds to the Hua-Jie AK-CN2 (and DN2, if the specification includes linear switches). This switch was used by Monterey and it was their response that the switch came from Hua-Jie that led to the discovery in the West of Hua-Jie.
The high similarity between Hua-Jie and Xiang Min switches currently prevents identity with certainty, but it is likely that any switch with these internals and mould numbering matching Himake's is AK-CN2. The official depiction of AK-CN2 (below) does not correspond to any known switch; it has the stationary contact of an alps.tw Type OA4 but the phosphor bronze click leaf of a T1. An example of this configuration is yet to be sighted.
alps.tw's example (from an Ortek MCK-101FX) shows mould numbering of NW:#,SE:#, while those in Focus FK-2001 used S:1A##, those in the Monterey K108 use S:1A##, and those in the Monterey K110/SIIG MiniTouch used S:1A## and S:## (with a keyboard found that uses both schemes side by side).
These switches are found in a great many keyboards; examples include:
- Monterey K110/SIIG MiniTouch
- Ortek MCK-84FX
- Ortek MCK-101FX
- Monterey K108
- Some Focus FK-2001
- ELSA Communications MAK-98
- Unidentified "Glidepoint Control"
