Editing Keyboard profile (section)

===Notable profiles===
====OEM profile====
Most vintage and modern mechanical keyboards have keycaps in what is called "Standard Profile" or "OEM Profile". The profile is used for keycaps with different [[Keycap mount|key mounts]] and several switch families, including [[Cherry MX]], [[Alps SKCL/SKCM series]] and [[Mitsumi miniature mechanical]].

Example keyboards include keyboards made by [[Costar]] (such as [[Filco Majestouch]] and [[WASD Keyboards]]), [[Das Keyboard]] (III), [[iOne]], [[SteelSeries]], [[Chicony]], etc.
There are also [[rubber dome]] keyboards that have this profile, but those usually have a standard [[Keycap mount|key mount]] and separate sliders over each dome.

====Cherry====
Keyboards from [[Cherry]] corporation in the [[:Category:Cherry G80 series|G80]] and [[:Category:Cherry G81 series|G81]] series have contoured keycaps that are somewhat lower than the "standard" profile. Cherry's keys are sharper on the bottom than most other manufacturer's keys.

Modern Cherry keyboards have the same 'B' row profile on the two bottom-most rows, but some vintage Cherry keyboards have the 'A' row profile on the bottom row, which is higher and more angled.
All Cherry keyboards with row 'A' are ''winkeyless'', but not vice versa.

[[QWERKeys]]'s "J series" is a copy of Cherry's profile row E,D,C,B but QWERkeys numbers them 1,2,3,4 from the top.

====Signature Plastics DCS profile====
[[Signature Plastics]]' popular [[Signature Plastics DCS-family|DCS family]] is ''mostly'' profile-compatible with Cherry Corp.'s keys, but not exactly. Most notably, the profile for the bottom two rows (row 4 profile) is angled more than Cherry's row 'B', while being also lower than Cherry's now deprecated row 'A'.
This can cause inconsistencies when using modifier keys from an [[Adapter kit|adapter kit]] made by SP together with Cherry keys on the same row.

The DCS profile is available with several types of mounts, including [[Keycap mount#Cherry MX mount|Cherry MX]]-compatible "U" mount and [[Keycap mount#Alps mount|Alps]]-compatible "Z" mount.

====Vintage Apple Macintosh====
Vintage [[Apple]] keyboards (with [[Alps SKCL/SKCM series]] or [[Mitsumi standard mechanical]] switches) have a completely Apple-specific contoured profile that is not compatible with any other manufacturer. It is almost as if the rows have been moved one step down.
