Abstract
Official abstract text for this publication.
The key assembly comprises a keycap having a touchsurface for receiving a press force that moves the keycap from an unpressed position toward a pressed position. The keycap has first and second ramp contacting features comprising first and second angular protrusions. The first and second angular protrusions have first and second protrusion angles relative to first and second side portions of the keycap (respectively). The key assembly also has a base having first and second ramps that contact the first and second ramp contacting features and guide the keycap in the press direction and the second direction as the keycap moves from the unpressed position toward the pressed position. The base has first and second angular features configured to contact the first and second angular protrusions of the first and second ramp contacting features (respectively) to resist rotation of the keycap as the keycap moves toward the pressed position.
First claim
Opening claim text (preview).
What is claimed is: 1. A key assembly, comprising: a keycap having a touch surface for receiving a press force that moves the keycap from an unpressed position toward a pressed position, the unpressed position and pressed position separated in a press direction and a second direction orthogonal to the press direction, the keycap having first and second ramp contacting features comprising first and second angular protrusions having first and second protrusion angles relative to fir…
