The disclosure provides a key structure, which includes a support, a keycap, a linkage, a circuit layer, and a trigger mechanism. The keycap can be lifted and lowered above the support. The linkage is movably connected to the support and the keycap. The support is located between the circuit layer and the linkage. The trigger mechanism is disposed between the circuit layer and the keycap. The key structure of the disclosure provides a disposition of a support spaced circuit layer and a linkage.

Key structure and keyboard module

A keyboard structure including a base, at least one key and an electronic element is provided. The key is disposed on the base and sequentially includes a cap, a limiting structure, an elastic member and a membrane switch from top to down, wherein the elastic member is disposed on the membrane switch, the cap is disposed on the elastic member, and the limiting structure connects the cap and the base, such that the cap is configured to move relative to the base in a vertical direction. The electronic element is disposed on the membrane switch and is surrounded by an electrostatic protection zone, wherein the membrane switch has a hole corresponding to the electrostatic protection zone.

Keyboard structure

A key structure includes a key cap, a supporting board, a bridge assembly, a first supporting part, a second supporting part, an attractable element and a magnet. The bridge assembly includes first and second hinge parts. The first hinge part has a first pivot coupling portion. The second hinge part has a second pivot coupling portion. The first and second supporting parts are coupled to two ends of the first and second pivot coupling portions, respectively, wherein the first and the second supporting parts are disposed on the supporting board, a material of the first supporting part is different from a material of the supporting board, and a material of the second supporting part is different from the material of the supporting board. The attractable element is disposed on the second hinge part. The magnet is correspondingly located under the attractable element.

Key structure

A key structure includes a key cap, a bridge assembly, a first supporting part, a second supporting part, an attractable element and a magnet. The bridge assembly includes first and second hinge parts. The first hinge part has a first pivot coupling portion and a first connecting portion. The second hinge part has a second pivot coupling portion and a second connecting portion, wherein the first and second connecting portions are connected on an axis, and the first and second hinge parts rotate with respect to the axis. The first and second supporting parts are coupled to two ends of the first and second pivot coupling portions, respectively. The attractable element is disposed on the second hinge part. The magnet is correspondingly located under the attractable element for providing a magnetic force, so that the attractable element is attracted and positioned by the magnetic force.

A key structure includes a supporting board, a base board, a pre-stressing force applying assembly, a key cap, a pivot assembly, an attractable element and a magnetic element. The pre-stressing force applying assembly is connected to the supporting board or the base board. When the magnetic element is under the first attractive position, the first end of the attractable element is attracted by the magnetic force and moved to the first attractive position, and the pre-stressing force applying assembly generates a first pre-stressing force; when the magnetic element is under the second attractive position, the second end of the attractable element is attracted by the magnetic force and moved to the second attractive position, and the pre-stressing force applying assembly generates a second pre-stressing force. The first pre-stressing force or the second pre-stressing force reduces the resistance during the sliding of the base board or the supporting board.
