| A keyswitch structure includes a base, a keycap, a lift mechanism, and a magnetic member. The keycap is capable of moving up and down relative to the base through the lift mechanism. The lift mechanism includes a support that has a side edge portion, abutting against the base through a sharp edge, and a magnetic portion at the side edge portion. The magnetic portion extends outward from the side edge portion. The support is movably connected to the keycap through another side edge portion of the support. The magnetic member is disposed on the base corresponding to the magnetic portion. The magnetic portion and the magnetic member produce a magnetic attraction force therebetween. When an external force applied to the keycap is eliminated, the magnetic attraction force drives the support to rotate about the sharp edge relative to the base, so that the keycap moves away from the base. | ||||||

A forced portion of the connecting assembly is configured to be moved by a forcing structure of the movable plate to make the keycap move between an opening position and a closing position relative to the bottom plate. When the movable plate is located at the first position, the forcing structure and the forced portion are separated by a distance, and the keycap is located at the opening position. | ||||||
| 248 | Touchsurface assembly utilizing magnetically enabled hinge | US13960083 | 2013-08-06 | US09324515B2 | 2016-04-26 | Douglas M. Krumpelman; Cody G. Peterson |
| Methods and apparatus for a touchsurface assembly such as a key assembly are described. The touchsurface assembly includes a base, a keycap and a magnet physically coupled to the base near to the keycap. A keycap coupler has a first portion magnetically attracted to the magnet and a second portion cantilevered from the magnet to support the keycap in an unpressed position. When a press force applied to the keycap overcomes a magnetic force pulling the keycap coupler toward the magnet, the keycap coupler pivots away from the magnet to allow the keycap to move toward a pressed position. | ||||||

| 254 | Keyswitch with magnetic restoration mechanism | US14472382 | 2014-08-29 | US09236204B2 | 2016-01-12 | Chien-Shih Hsu; Zuei-Chown Jou |
| A keyswitch structure includes a base, a keycap, at least one lift mechanism, a link, and a restoration mechanism. The lift mechanism is connected to and between the base and the keycap. The link is moveably on the base. The restoration mechanism is disposed on the link and the base and can generate a restoration force. When the keycap is pressed down by a user to move toward the base, a sliding portion of the lift mechanism slides on the base to drive the link to move relative to the base. Further, when the pressing on the keycap by the user is eliminated, the restoration force urges the link to move to drive the sliding portion to slide reversely, so that the keycap moves away from the base. | ||||||
| 255 | OPTICALLY TRANSMISSIVE KEY SWITCH MECHANISM FOR DISPLAY-CAPABLE KEYBOARDS, KEYPADS, OR OTHER USER INPUT DEVICES | US14745141 | 2015-06-19 | US20150364276A1 | 2015-12-17 | Ming LI; Kok Kiong LOW |
| Key switch mechanisms are typically used for mediating user input to computing devices. A key switch mechanism provides immediate tactile feedback to a user upon user-actuation thereof. Unlike touchscreen interfaces, existing key switch mechanisms of conventional keyboards do not provide a user with a dynamically changeable interface. Described is a key switch mechanism that comprises a circuit module, a key cap and a linkage mechanism for guiding travel of the key cap substantially along a travel axis. The linkage mechanism comprises a positioning board and a main link pivotably inter-coupling the positioning board and the key cap. The main link substantially impedes tilt of the key cap away from the travel axis during travel of the key cap therealong from a released position, whereat the key cap is biased, to a depressed position whereat a control signal is generated. | ||||||

| A keyswitch mechanism having reduced key rattle and a keyboard having reduced key rattle. A rattle suppression mechanism may be formed on a portion of the scissor mechanism or on a portion of the keycap. The rattle suppression mechanism is configured to maintain force on the portion of the scissor mechanism abutting the keycap. | ||||||
| 259 | Anti-rotational buttons | US13607541 | 2012-09-07 | US09099264B2 | 2015-08-04 | Anna-Katrina Shedletsky; Colin M. Ely; Phillip Michael Hobson |
| Systems and methods for providing input component assemblies with anti-rotational buttons in electronic devices are provided. The input component assembly includes a switch, a button positioned over the switch, where the button is operative to close at least one circuit of the switch when the button is depressed towards the switch, and at least one pin positioned underneath the button, where the at least one pin is operative to engage with a surface to assist in preventing rotation of the button, when the button is depressed towards the switch. | ||||||
| 260 | Input device and lifting structure for the input device | US14092986 | 2013-11-28 | US09092065B2 | 2015-07-28 | Lu-Yuan Hsueh |
| An input device has a base, two shafts, a touchpad and a switch. The shafts are pivotally connected between the base and the touchpad, and intersect each other. When the touchpad is pressed, the shafts rotate relative to the base and the touchpad simultaneously. As the shafts intersect each other, an intersection of the shafts is nearby or exactly on a center of the touchpad, such that the shafts can pull down the touchpad from the center. Thus, no matter what location on the touchpad is pressed, a pressing force is spread uniformly, which makes the touchpad move down evenly without tilting. Besides, pulling down the touchpad from the center can further prevent leverage and deformation of the touchpad, thereby avoiding affecting the user's feel of pressing. To sum up, the input device can make the touchpad move down evenly, and prevent the touchpad from deformation. | ||||||
