Embodiments disclosed herein describe a base, an operation unit that moves in a contacting/separating direction with respect to the base in response to an external force, and a pair of link members turnably coupled to each other by a coupling portion and configured to guide movement of the operation unit in the contacting/separating direction. The pair of link members includes a first curved portion and a second curved portion that are supported on the base, and a first rotary spindle and a second rotary spindle that are supported on the operation unit. When the operation unit moves in the contacting/separating direction with respect to the base, the first curved portion and the second curved portion slide with respect to the base in a direction substantially perpendicular to the contacting/separating direction and in a direction substantially perpendicular to a turning shaft of the pair of link members.

Embodiments are directed to a low profile key for a keyboard having an overmolded support structure. In one aspect, an embodiment includes a key cap having an illuminable symbol. A support structure having a pair of overmolded wings may pivotally couple to the key cap. A switch housing may surround the support structure and connect each of the first and second wings. A tactile dome may be at least partially positioned within the switch housing and configured to bias the key cap upward. A sensing membrane may be positioned along an underside surface of the tactile dome and configured to trigger a switch event in response to a collapsing of the tactile dome caused by a depression of the key cap. A feature plate may be positioned below the sensing membrane. A light guide panel may define at least one light extraction feature that may be configured to propagate light toward the key cap and cause illumination of the illuminable symbol.

A method for assembling a keyswitch device includes: connecting a first covering portion to a surface of a first housing; connecting a second covering portion to a connection base comprising an engaging portion; rotatably engaging the engaging portion with an engaging structure; connecting the engaging structure to the first housing; and fixing a second housing to the first housing such that the first housing and the second housing constitute a recess communicating with the surface, wherein the engaging structure partially protrudes into the recess.

The invention provides an input device including a holder, a first wheel, a slider, and a first pressure part. The first wheel is disposed on the holder, and includes a side surface, a circle center, and a segment adjusting structure. The segment adjusting structure is disposed on the side surface in a manner of surrounding the circle center. The slider is disposed on the holder, and is movable relative to the holder to move toward or away from the circle center. The first pressure part includes two first ends. One of the first ends is connected to the slider, and as the slider moves toward or away from the circle center, interference between the other first end and the segment adjusting structure is increased or reduced.

A key unit and a keyboard using the same are provided. The key unit includes a circuit board, an elastic element, a keycap, and a processing circuit. The circuit board includes a capacitance sensing circuit embedded therein, and the capacitance sensing circuit includes a pair of sensor electrodes. The elastic element is disposed on the circuit board. The keycap is moveably disposed above and spaced apart from the circuit board. The elastic element is disposed between the keycap and the circuit board so that the keycap moves between a non-depressed position and a depressed position with respect to the circuit board. The processing circuit is electrically connected to the pair of sensor electrodes to obtain a variation of a coupling capacitance between the pair of sensor electrodes and to determine whether the keycap is touched or depressed according to the variation of coupling capacitance.
