Datacomp Electronics Co., Ltd. is a Taiwanse keyboard and switch manufacturer founded September 1980.
Not only have they appropriated a trademarked brand for their products, but they persist the incorrect spelling of using all capitals in “Alps”. It’s interesting to note that they also offer “DSA” keycaps: DSA is not an industry term but rather a specific keycap family from Signature Plastics in the US (denoting DIN-compliant spherical, all rows same profile, the popular flat spherical family).
Datacomp are one of the Taiwanese manufacturers who will not return any correspondence.
Datacomp used Sung Wei for some, but not all of their PCBs.
