Abstract
A key assembly in accordance with embodiments of the invention comprises a base, a keycap, a biasing mechanism, a first linkage, and a second linkage. The keycap is spaced from the base along a press direction and configured to move between an unpressed position and a pressed position relative to the base. The unpressed and pressed positions are separated by a first amount in the press direction and a second amount in a lateral direction orthogonal to the press direction. The first amount is at least as much as the second amount and no larger than twice the second amount. The biasing mechanism is configured to bias the keycap away from the base. The first and second linkages are rotatably coupled to the base and the keycap.
