摘要： A keyswitch structure includes a base, a keycap, a first support, a second support, and a connection structure. The keycap moves up and down relative to the base through the first support and the second support. The connection structure is disposed on the base and includes a vertical-motion limiting part and a horizontal-motion limiting part. The first support includes a rod-shaped connection portion and is connected to the connection structure through the rod-shaped connection portion. The vertical-motion limiting part prevents the rod-shaped connection portion from vertically moving. The horizontal-motion limiting part limits the horizontal movement of the rod-shaped connection portion. The vertical-motion limiting part and the horizontal-motion limiting part are separated in the rotation axis of the rod-shaped connection portion.

摘要： A keyswitch assembly includes a switch module, a support mechanism, and a blocking mechanism. The switch module includes a substrate, a signal generator, and a signal sensor. The signal generator provides a sensing signal. The signal sensor receives the sensing signal to obtain a sensing intensity. The support mechanism is disposed on the substrate. A top portion of the support mechanism moves in response to a pressing force. The blocking mechanism includes a pivoting portion rotatably disposed on the substrate, a connecting piece extending from the pivoting portion and movably connected to the support mechanism to be driven by the top portion to swivel relative to the substrate, and a blocking piece extending from the pivoting portion and driven by the connecting piece to be inserted into or escape from the gap between the signal generator and the signal sensor to change the magnitude of the sensing intensity.

摘要： A luminous keyswitch includes a keycap having a light-transparent portion, a baseplate, an up-down mechanism with two ends respectively moveably connected to the keycap and the baseplate, a function sheet disposed on or under the baseplate, and a light source disposed on the function sheet within a vertical projection of the keycap and connected by a copper wire to provide a light illuminating the light-transparent portion. The function sheet includes a flexible upper circuit layer having a first contact point, a flexible spacer layer having a hole, and a flexible lower circuit layer having a second copper contact point, a third copper contact point, a first copper wire connected to the second copper contact point, and a second copper wire connected to the third copper contact point. When the keycap is pressed, the first contact point passes through the hole to electrically connect the second and third copper contact points.

摘要： A keyswitch assembly includes a switch module, a support mechanism, a blocking mechanism, an enhancing light source, and a backlight source. The switch module includes a substrate, a signal generator, and a signal sensor. The signal generator generates a sensing signal. The signal sensor receives the sensing signal to obtain a sensing strength. The support mechanism is disposed on the substrate. The blocking mechanism is disposed on the substrate and has a light-permeable portion. A portion of the blocking mechanism inserts into or escapes from a gap between the signal generator and the signal sensor. The backlight source is disposed on the substrate and located outside the vertical projection of the blocking mechanism on the substrate. The enhancing light source is disposed on the substrate and located within the vertical projection of the blocking mechanism on the substrate and corresponds to the light-permeable portion.
