A keyswitch structure includes a lift mechanism and a keycap. Two supports of the lift mechanism support the keycap. There can be a spring structure connecting the two supports for driving the two supports to lift the keycap. The lift mechanism defines a central space extending through the whole lift mechanism in a vertical direction. The spring structure does not enter the central space. The two supports abut against and constrain each other through corresponding structures, to mutually rotate with respect to a rotation axis. The keyswitch structure can include a switch. The switch includes an intermediate support, detachably abutting downward against the lift mechanism or the keycap, and a resilient part, detachably abutting downward against the intermediate support. In the process of pressing the keycap, the intermediate support is separated from the lift mechanism or the keycap, so that the contact force of the switch can be maintained constant.

A keyswitch structure includes a base, a keycap, a lift mechanism and a light-emitting part. The lift mechanism includes a first support, a second support, and a spring structure. The first support and the second support are connected to and between the base and the keycap, so that the keycap can move relative to the base in a vertical direction. The spring structure is a single structural part and is connected to the first support and the second support and drives the first support and the second support to lift the keycap in the vertical direction. The lift mechanism as a whole defines a central space that extends through the whole lift mechanism in the vertical direction. The spring structure does not enter the central space. The light-emitting part is disposed on the base corresponding to the central zone, and emits light to illuminate the keycap.

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.

A keyswitch structure includes a keycap having a lower surface and an engaging portion protruding from the lower surface, the keycap moving to a lower position when the keycap is pressed, a linking bar coupled with the engaging portion, a distal end of the engaging portion being lower than the linking bar when the keycap moves to the lower position, a baseplate disposed below the keycap, the baseplate having a recessed space corresponding to the engaging portion, and a buffer film disposed on the baseplate, the buffer film substantially extending over the recessed space and having a deformable portion corresponding to the recessed space, wherein when the keycap moves toward the baseplate to the lower position, the distal end of the engaging portion pushes the deformable portion to make the deformable portion extend into the recessed space.

A key mechanism is disclosed. The key mechanism comprises a keycap, a dome support structure positioned relative to the keycap and defining an opening, an actuation mechanism coupled to the keycap, and a collapsible dome positioned in the opening of the dome support structure. The actuation mechanism is configured to movably support the keycap relative to the dome support structure. The dome comprises an upstop member configured to limit upward travel of the collapsible dome.

The invention relates to a switching-operation arrangement for a motor vehicle, having a movable actuating surface. The actuating surface has an extent along a first axis and a second axis, which are located perpendicularly to one another. The actuating surface interacts with a displacement means such that the actuating surface can be moved linearly, in the direction of a third axis (z), by at least one distance from a starting position into an actuating position, the third axis (z) being located perpendicularly to the first and second axes. The actuating position is in the form of a switching position and acts with switching action on a switching element or a sensor. The displacement means includes a guide means for guiding the actuating surface along the first axis and at least one braced-in elastic element for guiding the actuating surface along the second axis.

A key structure includes a base plate, a key pedestal, a switch element and a keycap. The key pedestal includes an opening and at least one elastic element. The keycap includes a triggering post and at least one contacting part. The key pedestal is installed on the base plate. The switch element is installed on the base plate and disposed within the opening of the key pedestal. The triggering post of the keycap is inserted into the opening of the key pedestal. The switch element can be triggered by the triggering post. The elastic element of the key pedestal is aligned with the corresponding contacting part. The contacting part of the keycap is continuously pushed against the corresponding elastic element of the key pedestal. Consequently, the keycap is maintained in a horizontal state and not tilted.

A user interface for a home appliance comprises a circuit board having at least one mechanically actuated switch having a first area. The user interface further comprises an input interface having at least one button defining a second area, greater than the first area, and having an actuator corresponding to the switch. The button is coupled to at least one of the circuit board or the input interface for relative movement between an actuation position, where the actuator actuates the switch, and a non-actuation position, where the actuator does not actuate the switch.

The disclosure provides a keyboard including a bottom plate, a key unit and a shielding layer. The bottom plate includes a through hole. The key unit is disposed on the bottom plate. The shielding layer covering a portion of the bottom plate includes a main part and an extension part extending from the main part toward the through hole. The shielding layer is provided with a black surface, and an orthographic projection of the key unit on the shielding layer overlaps the black surface.

A keyswitch structure includes a keycap, a base, and two supports pivotally connected to each other relative to a rotation axis and connected to and between the keycap and the base. One of the supports includes a first shaft recess, a first shaft portion, and a division slot formed therebetween; the other support includes a second shaft recess, a second shaft portion, and a division wall therebetween. The two supports are pivotally connected relative to the rotation axis by the first shaft portion and the second shaft portion rotatably disposed in the first shaft recess and the second shaft recess respectively. Therein, the division wall is inserted into the division slot. The keycap can move up and down relative to the base through the two supports.
