A light switch hook assembly including a light switch plate and a hook extending outwardly therefrom. A fastener is inserted through an aperture defined in the hook and then into a hole defined in the light switch plate. The end of the fastener is subsequently inserted into an opening defined in a light switch mounted within an electrical connector box. The light switch plate may already be installed on a wall. In this instance, a fastener is removed from this pre-existing light switch plate, the hook is positioned against the plate, and the fastener is inserted through the aperture in the hook, through the hole from which the fastener was previously removed, and into the opening in the light switch. A cover may be engaged with the hook to cover the head of the fastener. An article may be hung on the hook.

The present application discloses a pressure switch which includes a tube structure, a pressure transmitting assembly, a microswitch, and corrugated sheets. The pressure transmitting assembly disposed inside the tube structure includes a guide rod with a piston, and a fluid chamber providing working pressure is defined between the piston and a fluid inlet. The microswitch is disposed at another end of the tube structure away from the fluid inlet and can be actuated by the guide rod. The corrugated sheets are fixed inside the tube structure and stacked on the piston structure so as to form a sealing and pressure transmitting interface for the pressure switch. Therefore, the pressure switch has good sealing property, good buffering capacity, and enhanced mechanical response rate with the corrugated sheets and is suitable for precision pressure measurement and control in an environment with high pressure and high frequency vibration.

A vacuum bottle that is intended for an electrical switching device includes a cylindrical body of insulating material closed at each end respectively by a first metal cover and a second metal cover, and a mobile electrode that passes through the first cover and that cooperates with a fixed electrode between a closed position in which the two electrodes are in contact with each other and an open position in which the two electrodes are separated. The bottle includes the second cover corresponding to the fixed electrode of the vacuum bottle.

A key structure includes a base, a bracket, a sensing circuit, an elastic member, a key cap, and a screwing member. The bracket is disposed on the base, the sensing circuit is disposed on the bracket, and the sensing circuit has an opening. The elastic member is disposed on the sensing circuit and covers the opening. The key cap is disposed on the elastic member. The screwing member passes through the opening and screws the bracket to the base, and the key cap, the elastic member, and the screwing member are coaxially arranged. In addition, a portable computer.

According to an embodiment, a switch attachment member includes a support that is formed to be attachable between a steering wheel and a steering boss, and supports a switch. The support is formed to be capable of changing a position of the switch.

A layer-structured, open-design keyboard includes a main body and a tray attached to the main body from below. The main body has key mechanisms and keycaps mounted on tops of the key mechanisms. The main body includes an upper-layer plate, a middle-layer plate, a circuit board, and a lower-layer plate arranged from a top to a bottom of the main body successively in a spaced manner, so as to define three clearance spaces that communicate the interior of the main body with the exterior.

[Object] To propose a new and improved button unit and electronic device, in which an attitude of a button of an electronic device can be made stabilize. [Solution] A button unit including: an operating member that presses a member to be pressed, in response to being press operated; and an urging member that urges the operating member against the member to be pressed. In this way, there can be provided the new and improved button unit and electronic device, in which the attitude of a button of an electronic device can be made stabilize

Electronic devices are provided that have components. A housing protrusion may be interposed between a display cover layer and display components. A button may have a button member. A support structure for a dome switch in the button may have a screw hole. A housing may have screw holes through which a screw passes. The screw may also pass through the screw hole of the support structure to hold the switch structure near the button member. A clip may have a spring. A metal plate may prevent the clip from becoming worn by the spring. A display may be mounted on a ledge in a device housing. The ledge may have gaps with supports and removed corners.
