The present disclosure relates to an operating member including: a support; an actuating part, which defines an actuating surface is mounted on the support by a mount to be movable relative to the support, by manual actuation against a resetting force, while carrying out an actuating movement from a rest position into a depressed position; a detector having at least one force sensor, wherein the detector is adapted to detect at least one position of the actuating part; wherein the mount includes a guidance mechanism having at least one pair of coupled levers, wherein the levers are each pivotably mounted on the support by a first pivot joint and on the actuating part—by a second pivot joint to cause a pivoting movement of the at least one pair of coupled levers by the actuating movement, wherein the guidance mechanism further includes at least one coupling rod.

Methods for assembling low-profile, singulated keyboards by prefabricating key assemblies onto a chassis strip that is divided into individual key assemblies only after the substrate is affixed to a feature plate of keyboard. For example, a row of key assemblies is fabricated onto a chassis strip. The row corresponds to a partial or complete row of keys of the keyboard. The chassis strip is thereafter affixed to a feature plate in a specific location, thereby aligning each prefabricated key assembly to a precise location on the feature plate. While connected, each prefabricated key assembly is independently affixed to the feature plate. Thereafter, interconnecting portions of the chassis strip between the prefabricated key assemblies are removed, thereby singulating each key assembly.

Key assemblies having a foldable stabilizer are disclosed. The stabilizer can be positioned under a keycap to help guide the keycap and limit rotation or movement when the key is pressed. The stabilizer can have a pointed-star shape with multiple folding axes and can have multiple points of connection or linkage to the keycap or other surrounding components. The stabilizer can unfold or flatten as the keycap is pressed and can fold as the keycap is raised.

A keyswitch structure includes a base plate, a keycap, and two supports connected to the base plate and the keycap. The keycap is movable relative to the base plate through the two supports. The support is pivotally connected to the base plate through a pivotal connection structure that includes a guiding slot and a protruding shaft oppositely disposed on the support and the base plate. The guiding slot has an opening and an indentation portion. The opening is located at an upper end of the guiding slot. The protruding shaft enters the guiding slot from the opening to rotatably fit in the indentation portion, so that the support is pivotally connected to the base plate.

A key structure includes a base plate, a key cap, a supporting member, a link member, and a buffer member. The base plate includes a body portion and a protrusion portion protruding upward from the body portion. The body portion has an accommodating hole, the accommodating hole corresponds to the protrusion portion, and the protrusion portion has an opening. The key cap is disposed above the base plate. The supporting member is disposed between the key cap and the base plate. The link member includes a main body portion and an end portion. The main body portion is pivotally connected to the key cap, and the end portion is disposed at the opening of the protrusion portion. The buffer member is located below the end portion, and the end portion leans against the buffer member.

A detachable screen key structure mainly includes a key body having a hollow portion, key butting element and screen carrying element, where a key signal connecter is configured in the hollow portion, the screen carrying element is configured with a display element and a key cap is configured on the display element, and the display element is configured with a display butting element adapted to dock the key butting element. Whereby, a user can accommodate the key signal connecter for signal transmission inside the hollow portion so as to increase use beautification. Furthermore, since the display will be connected to the key butting element through the display butting element, the user is allowed to carry out the removal and replacement by themselves, which can increase use convenience.

The disclosure provides a key assembly, including: a baseplate, having a top surface and a recess groove recessed from the top surface, in which the recess groove is a blind hole; a hook, disposed on the baseplate, and extending upward from the top surface to form a hole between the hook and the top surface, in which an orthographic projection range of the hook and an orthographic projection range of the recess groove do not overlap each other; a key cap, disposed on the baseplate; an elastic member, disposed between the key cap and the baseplate; a link bar, connecting the key cap and the baseplate, in which the link bar has an extension portion passing through the hole; and a membrane, disposed on the top surface of the baseplate, in which the membrane covers at least part of the recess groove, and the extension portion abuts the membrane.

A keyboard device includes a membrane circuit board, a base plate and a key structure. The key structure a keycap, a first connecting element, a second connecting element, a stabilizer bar and an auxiliary bar. The first connecting element and the second connecting element are connected between the keycap and the base plate. The first connecting element has a first lateral side and a second lateral side. The second connecting element has a third lateral side and a fourth lateral side. The third lateral side faces the second lateral side. The stabilizer bar is pivotally coupled to the keycap, the first lateral side of the first connecting element and the fourth lateral side of the second connecting element. The auxiliary bar is pivotally coupled to the keycap, the second lateral side of the first connecting element and the third lateral side of the second connecting element.

Keyboards are disclosed that are retractable. Movable magnetic or mechanical linkage elements are configured to reposition keycaps and stabilizers between different relative positions. Structures in a movable layer can act on the keycaps or stabilizers to move the keycaps and stabilizers into a retracted position for storage and for saving space in an electronic device. The stabilizers can be scissor mechanisms, butterfly mechanisms, and similar devices. The movable layer can be moved in response to rotation of a hinge or other mechanical element in the electronic device.

Example implementations relate to dampened keycaps. In an example, a dampened keycap includes a keycap, a link bar to contact the keycap, where the link bar includes a main body and an arm having a hooked portion forming a distal end of the link bar, and a dampening material disposed on a distal end of the link bar.
