The present invention provides a keyboard device, including a plurality of key structures, where each key structure includes a thin-film circuit board, a key frame, an elastic element and a press assembly. The key frame is arranged on the thin-film circuit board, and includes a frame body and a bottom plate that are of an integrally formed structure. The bottom plate is located between the frame body and the thin-film circuit board, and has a through hole, and the thin-film circuit board covers the through hole. The elastic element is arranged on the thin-film circuit board, and a part of the elastic element is located in the through hole in the bottom plate. The press assembly is arranged in the key frame, and the elastic element is located between the press assembly and the thin-film circuit board. The present invention further provides a keyboard device assembly method.

A key structure is provided, including a key housing, a keycap, an elastic piece and a spring. The key housing comprises an interfering portion. The keycap is movably assembled to the key housing along a pressing axial direction. The elastic piece is movably assembled to the keycap along the pressing axial direction. The elastic piece comprises a protrusion, and the interfering portion is located on a movement path of the protrusion. The spring abuts between the keycap and the elastic piece. When in an initial position, the protrusion is stopped at the interfering portion. When an external force is applied to the keycap, in a pressing process, the keycap is moved relative to the key housing, and drives the protrusion to surmount and cross over the interfering portion. An elastic restoring force of the elastic piece causes the protrusion to hit the interfering portion to make a sound.

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.

The present disclosure provides light switch modules and methods of implementing a light switch module for a lighting control system. The light switch modules include a light switch actuator including an actuation surface. The light switch actuator is movable to connect an electrical flow path and to activate a tactile display housed in the light switch actuator. One or more tactile motions are applied on the actuation surface of the light switch actuator for selecting a lighting setting from among a plurality of lighting settings using the tactile display.

A keyboard includes a base, a keycap, and a connecting assembly. The keycap is located over the base. The connecting assembly is located between the base and the keycap and includes a first connecting member and a second connecting member connected to each other. Each of the first and second connecting members is connected to the base and the keycap. Two connected members of the base, the keycap, and the first and second connecting members are fixedly connected. When the keycap is pressed toward the base, at least one of the first and second connecting members elastically deforms to store elastic potential energy. When the keycap is released, said at least one of the first and second connecting members elastically recovers to return the keycap to its original position.

A lever switch which is capable of preventing loud operating noise from being generated during stepwise operation of an operating lever. The lever switch has a case, a click feeling generator placed inside the case, and a switch moving body placed inside the case and rotated with respect to the case by operating the operating lever. The click feeling generator has trough portions that abut against a convex portion of the switch moving body. Click feelings are given by the convex portion of the switch moving body sequentially abutting against the trough portions in response to stepwise operations of the operating lever. The convex portion of the switch moving body is urged toward the click feeling generator. The click feeling generator and the case are placed away from each other with a space left between them in a direction in which the first case is urged.

A push switch having the contact piece including a support part supported on a base member, a movable contact part, and an interconnection part interconnecting the support part and the movable contact part. The movable contact part is movable between a position contacting a first fixed contact part and a position separate from the first fixed contact part. The contact piece is configured so that, when a pressure reception member is pushed to be moved closer to a specific surface of the base member to cause change in shape of the movable member, the interconnection part is pushed by the movable member and the movable contact part is moved along operation directions. The movable contact part located at a position facing a through hole in the operation directions. The movable contact part has a size and shape to be allowed to pass through the through hole in the operation directions.

A switch device and a music generation device are provided. A switch device comprising: a switch; a housing; a movable shaft that moves along an axis direction of the movable shaft with respect to the housing to press the switch; an elastic member that biases the movable shaft to one end side of the movable shaft in the axial direction; and an arm for pressing the switch at a position eccentric from an axis of the movable shaft, wherein the switch is outside a range of the movable shaft in a view in the axial direction.

An accessory device having a first and second body is described. The second body may include a force feedback mechanism that responds to an input received at the first body causing a force feedback. The force feedback mechanism includes coils distributed throughout the second body, with each coil configured to receive an electrical current such that each coil provides an external magnetic field to magnetically couple with one or more magnets disposed in the first body, causing the first body to move in a direction toward the second body. The first body may return to its original position when the external magnetic field is no longer applied. In this regard, the movement of the first body defines the force feedback. Also, the first body may include a keyboard or a touch screen functioning with the force feedback mechanism. The accessory device may be used in conjunction with an electronic device.

A push switch having the contact piece including a support part supported on a base member, a movable contact part, and an interconnection part interconnecting the support part and the movable contact part. The movable contact part is movable between a position contacting a first fixed contact part and a position separate from the first fixed contact part. The contact piece is configured so that, when a pressure reception member is pushed to be moved closer to a specific surface of the base member to cause change in shape of the movable member, the interconnection part is pushed by the movable member and the movable contact part is moved along operation directions. The movable contact part located at a position facing a through hole in the operation directions. The movable contact part has a size and shape to be allowed to pass through the through hole in the operation directions.
