The present utility model discloses a combined mute switch comprising a base and an upper cover arranged above the base, an accommodating cavity being formed in the combination of the upper cover and the base, a guide core being arranged in the accommodating cavity; at least one upper elastically deformable silencing member is arranged on the upper cover and on the top wall of the accommodating cavity; at least one lower elastically deformable silencing member is arranged on a lower end of the guide core; an impact force of the guide core moving downwards is damped and silenced by the lower elastically deformable silencing member; and an impact force of the guide core moving upwards to be reset is damped and silenced by the upper elastically deformable silencing member. The combined mute switch provided by the present utility model achieves a mute effect when being pressed and popped to reset.

A switch structure includes a light-emitting part configured to receive power from a vehicle and to radiate light, a moving block located so as to surround the light-emitting part, a light-transmissive part configured to allow light radiated from the light-emitting part to pass through an opening in the moving block, and a film-printing layer located on a top surface of the light-transmissive part and including a symbol.

A keyswitch structure includes a base, a keycap, a lift mechanism and a light-emitting part. The lift mechanism includes a first support, a second support, and a spring structure. The first support and the second support are connected to and between the base and the keycap, so that the keycap can move relative to the base in a vertical direction. The spring structure is a single structural part and is connected to the first support and the second support and drives the first support and the second support to lift the keycap in the vertical direction. The lift mechanism as a whole defines a central space that extends through the whole lift mechanism in the vertical direction. The spring structure does not enter the central space. The light-emitting part is disposed on the base corresponding to the central zone, and emits light to illuminate the keycap.

A composite sheet metal component for an automobile comprises an inner metal sheet, an outer metal sheet and an intermediate polymer sheet arranged between the inner and the outer metal sheet. The intermediate polymer sheet comprises a semiconductor device and the outer metal sheet comprises at least one functional area.

A radiation therapy system includes an X-ray imaging system that is configured with a combined and simplified filter and collimator positioning mechanism. In addition, an X-ray imager of the RT system is only positioned at a few discrete locations within a plane that is a fixed distance from the imaging X-ray source when generating X-ray images. As a result, for each of these discrete imaging positions, the simplified filter and collimator positioning mechanism positions a specific collimator-filter combination in a specific location between the X-ray source and the imager.

Example methods and apparatuses of controlling a user interface with a plurality of input mechanisms are disclosed. One example method includes causing a first set of input mechanisms in the plurality of input mechanisms to be visually emphasized via a first visual technique while a second set of input mechanisms in the plurality of input mechanisms is not visually emphasized via the first visual technique, receiving a user input via an input mechanism that is included in the first set, based on the user input, determining a third set of input mechanisms in the plurality of input mechanisms and a fourth set of input mechanisms in the plurality of input mechanisms, and causing the third set of input mechanisms to be visually emphasized via the first visual technique while the fourth set of available input mechanisms is not visually emphasized via the first visual technique.

A keyboard switch, including a base; a static contact; a moving contact; an upper cover; a button configured to control the contact of the static contact and the moving contact; and a reset spring configured to control the reset of the button.

An illumination system and method are disclosed for maintaining a consistent change in illumination value among a group of illumination devices whenever a change command is manually sent from a keypad to those illumination devices. The consistent change results from maintaining a common start illumination value among not only the group, but also the keypad which controls the group. From the start illumination value, the keypad can then compute an end illumination value depending upon the amount of time that an increase or decrease in illumination value button is depressed and held. Since the change command can arrive at different illumination devices within the group depending upon where each illumination device is geographically located, a masking time is reserved after the button is released so that enough time is allocated for each of the illumination devices within that group to arrive at a common end illumination value.

The present invention relates to a keyboard switch including a base, a supporting member, a spring, a button and an upper cover. The supporting member includes a first plate connected to the base to seal the opening, a tube extending substantially perpendicularly from a surface of the first plate, and a plurality of blocks extending substantially perpendicularly from the first plate and configured around the tube. There is a gap between the tube and the plurality of blocks. The base and the supporting member may be made of different materials and colors from the base, so that the supporting member may have a good light-shielding performance and durability; and the base may be made of a collocation of different materials and colors, and has a wide design space.
