A push switch contains a circuit substrate, two fixed contacts disposed on the circuit substrate, a dome-shaped spring which is disposed above the two fixed contacts and can be displaced between a first position in which the two fixed contacts are in a non-conductive state and a second position in which the two fixed contacts are in a conductive state and a conductive elastic member disposed on a surface of the dome-shaped spring facing the circuit substrate and having a surface facing the two fixed contacts. At least the surface of the conductive elastic member facing the two fixed contacts has conductivity. When the dome-shaped spring is displaced to the second position, the two fixed contacts are in the conductive state through the conductive elastic member.

A backlight apparatus includes a light-guiding plate, a light-shielding membrane, a light-reflecting sheet, a plurality of first translucent glue bodies, and a plurality of second translucent glue bodies. The light-guiding plate has a plurality of through holes. Each of the first translucent glue bodies corresponds to one of the through holes. Each first translucent glue body is placed on a front surface of the light-guiding plate, and surrounds a respective circumference of the corresponding through hole to bond the light-shielding membrane thereabove and the light-guiding plate therebelow. Each first translucent glue body has a respective breach. Each of the second translucent glue bodies corresponds to one of the first translucent glue bodies, is placed via at least one portion thereof in the breach of the corresponding first translucent glue body, and bonds the light-shielding membrane thereabove and the light-guiding plate therebelow.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for using electrical button matrix scanning techniques to detect remote control buttons pressed by users. An example embodiment operates by detecting, using an electrical matrix scanning technique, an actuated electrical switch corresponding to a remote control action for a media device. The actuated electrical switch includes a first actuated electrode coupled to a first actuated electrical line of an electrical matrix, a second actuated electrode coupled to a second actuated electrical line of the electrical matrix, and a third actuated electrode coupled to a third actuated electrical line of the electrical matrix. In response to detecting the actuated electrical switch, the example embodiment operates by triggering an execution of the remote control action corresponding to the actuated electrical switch.

Provided herein is a keyboard assembly that includes a keyboard substrate, a plurality of keycaps, and a plurality of lifting supports. Each keycap is connected to the keyboard substrate by using a lifting support. The keyboard substrate is connected to a bottom plate and a top plate, with the bottom plate including a key accommodation groove that further includes a concave slope. The lifting support is located in the key accommodation groove, with one end abutting against the concave slope and being capable of sliding on the concave slope. In a process in which the top plate rotates to a first specified location, the keyboard substrate is driven to move, the lifting support descends, and the keycap descends. In a process in which the top plate rotates to a second specified location, the keyboard substrate is driven to move.

A keyboard device is disclosed. The keyboard device includes a base, a key top, a film actuator, a position sensor, and a controller. The key top is movably arranged on the upper surface side of the base. Disposed between the base and the key top, the film actuator bends according to an applied voltage. Also disposed between the base and the key top, the position sensor detects a position of the key top. The controller applies a voltage to the film actuator in order to generate a repulsive force corresponding to the position of the key top detected by the position sensor.
