20160055989 | KEYSWITCH STRUCTURE - 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. | 02-25-2016 |
20160064165 | KEYSWITCH STRUCTURE - The keyswitch structure uses two linkages form as V-shaped to support a keycap when the keycap is moved up and down. A first linkage and a second linkage are coupled with each other and also coupled with a support on a base respectively in a line contacting way, thereby forming a first axis, a second axis, and a third axis. The third axis is located between the first axis and the second axis. As the keycap is pressed to move downward, the keycap brings the two linkages and the support of the base to have relative rotation movement. Due to the geometric feature between the three axes, part of the linkages between the axes or the support of the base may be caused to slightly deform to provide a resilient restoring force that can move the keycap upward to a position not being pressed. | 03-03-2016 |
