With perhaps the most complex backhistory of any switch type, ALPS switches are much more difficult to categorize than most other mechanical switches. The ALPS company has been out of business for years, and the ALPS name is now used out of convenience to denote the stem type found on the switch. For the (current) purposes of MechanicalKeyboards.com, we'll typically lump any non-Matias ALPS style switch keyboards into this category. Just note that one black stem 'ALPS' may be different than another black stem 'ALPS'.
