  • Keyswitch mechanism with horizontal motion return mechanism
    Patent number: 10840038
    Abstract: Described herein are thin keyboard and thin keyboard overlay, as well as novel key assembly for uses on keyboards and keyswitches. The key assembly includes a top plate, a movable keycap, a support plate and flexible rods embedded in the support plate acting as springs. The underside of the movable keycap has at least one or several tapered protrusions which are located above the flexible rods. A vertical downward force on the movable keycap will enable the protrusion to flex the rods horizontally, thus creating a spring like mechanism that will return the movable keycap to its original position once the vertical force is removed.
