The utility model discloses a dual-conductive key switch comprising a base, a cover arranged above the base, and a conductive core, wherein it further comprises a first conducting component and a second conducting component which are triggered to conduct sequentially by the conductive core. According to the utility model, the dual-conductive key switch is provided for achieving dual-conductive function of pressing once and performing two actions for a product, which gives more functions to the key switch and provides better user experience.

A key includes a cap, a spring, a magnet, a spring supporting device, an upper limit device, a lower limit device, a displacement detection device, and a displacement determination device; the spring is located below the cap and, the spring is disposed on the spring supporting device; the magnet is placed on either of the upper limit device or lower limit device; the spring is magnetically pressed against the magnet; the displacement detection device is mounted on the spring and moves between the upper limit device and lower limit device following deformation of the spring; the cap is configured to generate a click motion; the displacement determination device is located at one side of the displacement detection device; the device moves back and forth with respect to the displacement determination device following the movement of the spring; and the displacement determination device is electrically connected with an external circuit.

What is presented is a key module (110) for a keyboard. The key module (110) comprises a key tappet (220) comprising a coupling portion for coupling to a keycap for the key module (110). The key module (110) also comprises a module housing (230) 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 an actuated position relative to the module housing (230). The key module (110) further comprises a wire bracket (560) for providing tactile and/or acoustic feedback. The wire bracket (560) is elastically deflectable in the course of the actuation movement. The wire bracket (560) is bent with an overall bending angle of less than 360 degrees. The wire bracket (560) is fixed to the key tappet (220).

A key structure includes a base, a movable mechanism movably positioned on the base, a sound generating member positioned on the base, and an adjusting unit movable relative to the base to be at a first position or a second position. The sound generating member has a hitting portion, which extends corresponding to an impact surface. When the adjusting unit is at the first position, and a pressing force is applied to the movable mechanism, the movable mechanism moves relative to the base and drives the sound generating member to move, so the hitting portion moves to hit the impact surface to generate a hitting sound. When the adjusting unit is at the second position, the adjusting unit restricts movement of the hitting portion, so the hitting portion cannot move to hit the impact surface.

A key structure includes a keycap, a scissors-type connecting element, a first knocking part, a resilience element and a second knocking part. The scissors-type connecting element is coupled to a bottom surface of the keycap. The scissors-type connecting element includes an inner frame and an outer frame. The first knocking part is disposed within a space surrounded by the inner frame. The resilience element is located under the first knocking part. The second knocking part is coupled to the bottom surface of the keycap and faces the first knocking part. While the keycap is pressed down, the second knocking part knocks on the first knocking part, and the first knocking part is moved downwardly. When the keycap is not pressed down, the first knocking part is moved upwardly and returned to an original position in response to an elastic force of the resilience element.

What is presented is a key module with a cover element and a tappet having a cam nose, wherein the tappet is supported to be movable along a movement axis by the cover element, wherein the tappet has a cylindrical keycap supporting portion in a passage area in which it projects through the cover element and has at least one rib on a guiding portion adjacent to the an keycap supporting portion on an outside. Furthermore, the key module includes a contactor unit formed and arranged to be taken along by the cam nose, and a contact piece formed and arranged for establishing electric contact with the contact nose. Moreover, the key module has a housing element for accommodating the contact piece, the contactor unit and the tappet, wherein the housing element has, for accommodating the guiding portion of the tappet, at least one accommodating bowl with at least one recess for accommodating the at least one rib of the tappet.

An input device includes a fixed electrode, a movable electrode, and a movable member. The movable member is configured to elastically deform by receiving pressing force to relatively displace the movable electrode toward the fixed electrode. The movable member has an outer peripheral part. The outer peripheral part includes a suppression structure configured to suppress the movable member from being elastically deformed by the pressing force.
