The present invention discloses a lifting key and a telescopic folding method. When a cover or handle is closed, the key is in a compressed state, and when the cover or handle of a device is opened, the cover or handle releases a traction mechanism, and the key drives a movable board to move by its own elastic force; after the movable board is displaced, a locked state between the movable board and an X balance frame is released, the X balance frame is unfolded under the force of a reset mechanism, and the key returns to a normal height; by slowly closing the cover or handle, the traction mechanism pulls the movable board under the action of the cover or handle, and the movable board moves back to return to an initial position. At this moment, the movable board is engaged with the X balance frame to make the key in the compressed state. The automatic lifting key of the present application can automatically expand the key when the cover is opened, and automatically contract the key when the cover is closed, which occupies a smaller space when the cover is closed, so as to make the notebook or Bluetooth keyboard thinner and easier to carry.

An open/closed indicating apparatus for a circuit breaker operating apparatus, comprising a button and an indicating element. The button is provided therein with a cavity. The indicating element is mounted within the cavity. The indicating element can rotate within the cavity. The button is provided thereon with an observation window. The indicating element can display different areas in the observation window while rotating. When a small number of gaps are provided between the indicating element and the housing, the impact on the angle of rotation of the indicating element is reduced, the indicating element can accurately indicate an open/closed state of a circuit breaker, and when a product is being fitted and assembled, a requirement on gap fitness is reduced for the assembly.

The present invention discloses a muted key module, an electronic device and an implementation method. The key module includes a switch member, a triggering mechanism and a supporting member, wherein the triggering mechanism is arranged corresponding to the switch member. The triggering mechanism can be moved along the contacting and separating directions of the switch member, thus to realize an ON or OFF operation of the switch member. A muting layer is arranged between the switch member and the supporting member. In the present invention, the muting layer is arranged between the switch member and the supporting member, so the impact force the between the triggering mechanism and the switch member can be cushioned by the muting layer, thereby reducing the noise produced when the key is pressed, thus to improve the quality of the final product as a whole.

The present disclosure provides a keyswitch comprising a baseplate, a circuit layer, an elastic part, a thin film, a keycap, and a linkage component. The circuit layer is disposed on the baseplate. The baseplate penetrates and is exposed from the circuit layer. The elastic part is disposed on the circuit layer. The thin film is disposed on the circuit layer. The thin film is provided with an opening. The baseplate penetrates and is exposed from the opening. The elastic part protrudes from the opening. The keycap is disposed above the elastic part and covers the elastic part. Two ends of the linkage component are respectively connected to the baseplate and the keycap. The elastic part is disposed in the linkage component. The linkage component drives the keycap to move up and down relative to the baseplate. The thin film is disposed on the movement path of the keycap.

A remote control device may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be configured to be mounted over an installed mechanical switch having a paddle actuator and may include a base and a control unit that is configured to be removably attached to the base. The base may include a frame, a clamp arm, a screw, and/or a sleeve. The clamp arm may be configured to secure the base to a protruding portion of the paddle actuator. The clamp arm may be attached to the frame at a pivot joint. The clamp arm may be configured to pivot about the pivot joint. The pivot joint may be located proximate to an endpoint or a midpoint of the frame.
