A keyswitch structure includes a base, a keycap, a frame disposed between the base and the keycap for providing a supporting and moving mechanism to the keycap, and another frame interacting with the former frame through a magnetic attraction force. When the keycap is not pressed, the magnetic attraction force drives the two frames to stably stand on the base and form a stable supporting structure, so that the keycap is located at a farther position relative to the base. When the keycap is pressed with an external force to move toward the base, the magnetic attraction force is overcome so that the two frames depart from each other; that is, the above stable supporting structure is temporarily destroyed. Once the external force applied to the keycap is eliminated, the two frames will form the stable supporting structure again due to the magnetic attraction force.

An apparatus (200) for remote manipulation of an electric equipment. The apparatus (200) comprises a supporting structure (204) adapted to be attached to the electric equipment adjacent to a button (202a) of the electric equipment and an elongated lever (206) attached to an axis (204a) of the supporting structure between a first end and a second end of the elongated lever such that the elongated lever is rotatable around the axis (204a). The apparatus (200) also comprises an actuation member (208, 210) adapted to actuate the first end of the elongated lever in response to an actuation signal (S) such that the elongated lever rotates around the axis (204a) so to move a finger portion (206c) at the second end of the lever against the button with a predefined maximum length. Thereby, a precise and well-defined movement of the finger portion (206c) can fairly easy be created with a predefined maximum length which is sufficient to press the button (202a) to activate some function as desired, but without risking damage of the button (202a).

A method for control device adjustment comprising applying a preload simultaneously to a plurality of shafts of a control device so as to take up initial assembly play, wherein the control device comprises an upper actuating element that is movable relative to a lower supporting mounting, a lower supporting mounting, a switch that is actuated by the upper actuating element, and an articulated structure that is interposed vertically between the upper actuating element and the lower mounting to keep the upper actuating element parallel to a horizontal plane during its vertical downward movement relative to a frame, and the at least one shaft. The method also comprises providing an adjustment stop fixed relative to the lower mounting and forming a stop surface that interacts with a facing portion of the shaft.

A device for operating multiple functions includes an operating element and a base. The base has side bearings with guide slots, hinge joints with pivot pins, and an actuator. The operating element is mounted in the guide slots to pivotably be mounted to the side bearings about an axis of rotation to thereby be movable between positions. At least one of the positions is assigned to a switching function. The operating element is mounted to the base on a centered bearing between the side bearings. The operating element is supported on the pivot pins. Upon the operating element being actuated to trigger a switching function, the actuator produces a haptic feedback by generating an actuating force on the operating element which causes the pivot pins to pivot in a direction parallel to the axis of rotation thereby causing the operating element to axially displace along this same direction.

An electronic device includes an operation button having a flange, and a device case formed with an opening into which the operation button is inserted. The device case is provided with a restricting portion that does not overlap the flange when the operation button is inserted into the opening in an orientation, and that overlaps the flange when the operation button is to be inserted into the opening in an orientation other than the orientation.

Disclosed herein are a switch module and a refrigerator having the same. The refrigerator includes with a dispenser installed on a door and a switch module to operate the dispenser. The switch module includes a push button having a front surface thereof disposed in a vertical direction and moving forwards and backwards by external force, and a link assembly allowing an upper portion and a lower portion of the push button to simultaneously move forwards and backwards while maintaining the front surface of the push button to be in a vertical direction during the forward and backward movement of the push button.

A key structure includes a base, a keycap, and a connecting rod. The base includes a structural plate and a connecting plate. The connecting plate is configured on the structural plate. The keycap is configured on the structural plate and includes a plate body and a first hook. The connecting rod is configured under the structural plate and extending towards an extension direction. The connecting rod includes at least a second hook. The connecting rod moves along the extension direction relative to the base to drive the second hook to be fastened to or detached from the first hook. When the first hook is detached from the second hook, the keycap moves relative to the connecting rod to expose the space between the keycap and the base, and then the key structure is easily repaired or cleaned.
