DCS family is a cylindrical keycap profile family from Signature Plastics and its predecessor Comptec.

"DCS" denotes Din standard height, cylindrical touch area, and sculptured keycap profile.[1].


DCS compared to other keycaps from Signature Plastics

DCS is predominantly made in double-shot moulded ABS, but a set in clear polycarbonate is also available. Single unprinted keycaps are also available in PBT but have not been sold as sets. Pad-printing has also been used for secondary and tertiary legends, and offered as primary method to OEMs.

DCS has thin walls, rounded corners and a coarse surface. It is otherwise quite similar to the size and slant to Cherry profile, except that it but differs significantly in the slant of the bottom rows.

Keys lack struts inside around the key stem, which means that down-stroke noise can not be damped with O-rings or silencing clips.



DCS is now sold as limited-editions of sets, and as blanks through Signature Plastics' Pimp My Keyboard shop. It has been made mostly with Cherry MX mount, but sets with Alps mount have also been available.

Before the shop opened, DCS had been sold to enthusiasts mostly through various group orders. Many novelty keycaps have been made.

A series of significant group buys have been organised by Deskthority member 7bit (for which he got much appreciation in the Deskthority Awards).

Before GMK started selling keycaps to consumers, the DCS profile was also often used for adapter kits for double-shot Cherry keys, sometimes with a replica Cherry font.


DCS in double-shot moulded ABS has been manufactured for OEMs since at least the mid-1990s. They are common on vintage Wyse keyboards. Adapter kits and replicas of Wyse keycaps have been made.

A rare earlier version with thicker walls has been found on the Wyse 85.
