A switch includes a housing, a movable member reciprocable in a movement direction relative to the housing and including an operation part located at an end of the movable member outside the housing, and a guide that guides the movable member in the movement direction. The operation part has a plurality of slopes extending linearly from the operation surface toward a distal end of the movable member outside the housing, sloping away from a central axis of the movable member toward the operation surface, and sloping in directions intersecting with one another as viewed in the movement direction.

A key structure includes a keycap, a connection assembly, engaging members, and a base plate. The connection assembly disposed between the base plate and the keycap is movably connected to the keycap and the engaging members, so that the keycap and the connection assembly engaged with the engaging members are positioned on the base plate. The base plate includes engaging protrusions protruding from an upper surface, so that the engaging members are bonded to the base plate through the engaging protrusions. Each engaging protrusion is located between two openings of the base plate, connects the two openings, or is disposed corresponding to the openings. Each engaging member covers one or more engaging protrusions through injection molding, and is fixed to the base plate. The engaging members are respectively disposed on the openings, fill the openings, or completely cover the engaging protrusions.

An electronic device includes a host, a display, a sliding plate, and a keyboard. The host has an operating surface. The display is pivoted to the host. The sliding plate is slidably disposed in the host, where the display is mechanically coupled to the sliding plate, and the sliding plate includes a plat portion and a recess portion that are arranged side by side. The keyboard is integrated to the host. The keyboard includes a key structure, where the key structure includes a key cap and a reciprocating element, and the key cap is exposed from the operating surface of the host. The reciprocating element is disposed between the key cap and the sliding plate and has a first end connected to the key cap and a second end contacting the sliding plate. The second end is located on a sliding path of the plat portion and the recess portion.

A key structure includes a keycap, a base plate and a wing-type supporting element. When the keycap is depressed in response to an external force, a first frame and a second frame of the wing-type supporting element are pushed by each other through protrusion structures and rotating shafts. Consequently, the first frame and the second frame can be swung relative to the base plate.

A key structure includes a keycap, an elastic buffering element, a base plate, a first supporting element, a second supporting element and an elastomer. The elastic buffering element is installed in a locking part of the keycap. The first supporting element is connected with the keycap and the base plate. The keycap is movable upwardly or downwardly relative to the base plate through the first supporting element. A first end of the second supporting element is pivotally coupled to the base plate. A second end of the second supporting element is penetrated through a pivotal hole of the elastic buffering element and a clamping recess of the locking part. The elastomer is arranged between the keycap and the base plate. An inner diameter of the at least one pivotal hole is slightly smaller than an inner diameter of the clamping recess.

A keyboard device includes plural key structures. Each key structure includes a plate assembly, a keycap assembly, an elastic element, a connecting member and a signal generator. The plate assembly includes a membrane switch. The keycap assembly is located over the plate assembly. The elastic element is arranged between the plate assembly and the keycap assembly. The connecting member is arranged between the plate assembly and the keycap assembly. The connecting member includes a triggering part. The signal generator is installed on the plate assembly. While the keycap assembly is moved toward the plate assembly through the connecting member, the triggering part is moved downwardly to trigger the signal generator to generate a first signal. After the signal generator is triggered, the keycap assembly is continuously moved downwardly and the membrane switch is triggered to generate a second signal.

A steering wheel remote control for a vehicle includes: a first button and a second button arranged on a top surface of the remote control and configured to move downward when being pressed; and a first printed circuit board (PCB) and a second PCB each of which arranged under the first button and the second button. The first PCB comprises a first switch terminal configured to be pressed downward to perform a first function when the first button moves downward, and the second PCB comprises a second switch terminal configured to be pressed downward to perform a second function when the second button moves downward. The first PCB and the second PCB are spaced apart from each other in a vertical direction.

A keyboard backlight module includes a light guide plate, a reflector, a light-emitting device and a first microstructure. The light guide plate has an output surface, a light guide pattern and a bottom surface disposed on an opposite side of the output surface. The light guide pattern is arranged on at least one of the bottom surface and the output surface. The reflector has a reflecting surface facing the bottom surface. The light-emitting device is disposed on one side of the light guide plate and configured to provide an incident light to the reflecting surface. The first microstructure is disposed on the reflecting surface, at least partially overlaps with the light guide pattern, and is configured to transform the incident light into a first reflected light.
