Editing Stabiliser (section)

===Wire===
The most common design is the wire stabiliser. A stiff wire runs from one end of the key to the other, connected to the keycap at each end, and to the keyboard plate or PCB via some form of restraint. The wire pivots against both the keyboard and keycap; pressing one end of the key rotates the wire, and the other end of the wire pulls its end of the keycap down accordingly. More than simply keeping the keycap moving vertically (important to prevent [[binding]]), this method actively keeps the keycap level.

This forms the basis of the stabiliser designs used by Costar, Cherry, SMK, and some of those from Alps and IBM.

The compound stabiliser design used in the [[Zenith Supersport SX]] for the enter key (shown below) is subject to Alps patent [https://www.google.com/patents/US4771146 US 4771146], filed in 1987 and with a priority date of 1985.
