Abstract

Official abstract text for this publication.

A magnetic keyswitch assembly includes a movable keycap, a support plate, a magnetic element, a frame and a switch component. The movable keycap includes a pivot and a metal part. The support plate supports the pivot. The magnetic element attracts the metal part, and a direction of a magnetic attractive force between the magnetic element and the metal part is perpendicular to a movement direction of the movable keycap. The frame is for accommodating the magnetic element. The switch component is disposed beneath the movable keycap. The magnetic element attracts the metal part so as to make the switch component in an OFF state as the movable keycap is undepressed. The movable keycap moves downward to trigger the switch component as the movable keycap is depressed to exceed a force threshold.

First claim

Opening claim text (preview).

What is claimed is: 1. A magnetic keyswitch assembly comprising: a movable keycap comprising a pivot and a first magnetic element, the movable keycap being for selectively rotating relative to the pivot, the movable keycap being a ladder-shaped structure; a second magnetic element for attracting the first magnetic element, a direction of a magnetic attractive force between the second magnetic element and the first magnetic element being perpendicular to a movement direction of t…
