A key structure, including a keycap, a scissor component, an elastomer, an optical switch, a shading portion, and a circuit board, is provided. The scissor component is formed of a first and a second supporter. The circuit board has two first and two second limiting units. The keycap has two third and two fourth limiting units. The first supporter is rotatably or slidably connected to the first and the third limiting units. The second supporter is rotatably or slidably connected to the second and the fourth limiting units. The keycap is disposed on the circuit board through the scissor component. The elastomer is interposed between the circuit board and the keycap. The optical switch includes an emitter and a receiver. The shading portion is disposed on the first or the second supporter to block a light signal transmitted between the emitter and the receiver.

An optical keyswitch includes a keycap, a support mechanism, and a switch module. The support mechanism is disposed below the keycap and configured to support the keycap moving upward and downward, the support mechanism comprising a first frame and a second frame, the first frame having a sliding end. The switch module includes a circuit board, an emitter, and a receiver, the emitter and the receiver are electrically connected to the circuit board, and the emitter emitting an optical signal to the receiver. When the keycap is pressed, the first frame is driven by the keycap to slide substantially parallel to the circuit board and block the optical signal with the sliding end, so the switch module is triggered to generate a triggering signal.

A push switch and a motor vehicle in which such a push switch is used. The push switch has a push cap, a baseplate, a switch element which is actuatable by the push cap, a first lever, and a second lever. The first lever and the second lever are mounted rotatably on the baseplate by means of bearing blocks and are each connected movably to the push cap at a first lever end. At a second lever end, the first lever and the second lever are connected movably to one another. The first lever and the second lever are designed such that they form mass compensation for the push cap.

A key switch device includes a base, a button mounted on the base so as to be contactable and separable, an elastic body disposed between the base and the button and configured to urge the button in a direction away from the base, and a linear reinforcement member provided on the button and configured to prevent the button from being inclined when the button is operated in a direction toward the base. An outer surface portion of the button includes a recessed support portion in which a part of the linear reinforcement members is disposed.

An input device includes an operation member vertically movably disposed on a support, urging means for urging the operation member upward, and an inclination preventive member reducing inclination of the operation member by coupling first and second ends of the operation member in a first horizontal direction and linking vertical movements of the first and second ends together. The inclination preventive member includes a main shaft extending in the first horizontal direction and rotatably and axially supported by the support, a pair of arms extending from opposite ends of the main shaft toward an identical side of a second horizontal direction crossing the first horizontal direction, and a pair of secondary shafts extending in the first horizontal direction from distal ends of the pair of arms, and rotatably and axially supported by the first and second ends. The pair of arms include short and long arms.

A key structure includes a keycap, a base plate and a scissor-type connecting assembly. The scissor-type connecting assembly includes a first connecting member and a second connecting member. One end of the first connecting member connects to the base plate, and the other end connects to the keycap. The first connecting member includes at least one pivot having a convex portion. One end of the second connecting member connects to the base plate, and the other end connects to the keycap. The second connecting member comprises at least one pivot hole, and the pivot is disposed in the pivot hole.

A keyswitch structure includes a base plate, a keycap, a lift mechanism connecting the keycap and the base plate, a movable part movably disposed relative to the base plate, a linking support, and a magnetic part on the base plate. The linking support has a pivotal connection portion, a magnetic portion, and a driving portion. The magnetic part and the magnetic portion produce a magnetic attraction force therebetween. When the movable part is located at a first position, the pivotal connection portion is rotatably disposed on a protruding portion of the movable part, and the magnetic attraction force drives the keycap through the linking support to move away relative to the keycap. When the movable part moves from the first position to a second position, the protruding portion moves away, so that the pivotal connection portion falls down and the keycap moves toward the base plate.

What is presented is a key module (110) for a keyboard. The key module (110) comprises a key tappet (220). The key module (110) also comprises a module housing (230). The module housing (230) is formed to movably accommodate the key tappet (220), in order to enable a translational actuation movement of the key tappet (220) between a rest position and in an actuated position relative to the module housing (230). The key module (110) further comprises a trigger element (240) for triggering an actuation signal of the key module (110) in response to the actuation movement. The trigger element (240) is attached to the key tappet (220). The trigger element (240) is a contactor for electrically shorting contact pads of a circuit substrate of the keyboard. The trigger element (240) comprises more than to elastically deformable contact fingers for contacting the contact pads after different pre-travel paths in the course of the actuation movement.
