An illuminated keyswitch includes a base, a keycap, a lift mechanism, and a light source. The keycap includes a cap body and a light guiding rod. The lift mechanism is connected to between the light guiding rod and the base, such that the keycap can vertically move relative to the base through the lift mechanism. The light source is disposed between the light guiding rod and the base and emits light toward the light guiding rod. The light enters the light guiding rod through an end portion of the light guiding rod and then emits out the light guiding rod from another end portion of the light guiding rod and a side surface adjacent to the another end portion toward the cap body. Thereby, the whole cap body can receives relatively uniform back light.

A touch-sensitive rotary control device with an illumination function includes a rotary encoder having a conductive outer casing and a rotatable shaft extending from it, the shaft operating as a light guide for a light source located in the rotary encoder, a conductive sleeve mechanically coupled to and surrounding the side of shaft, and electrically coupled to the conductive outer casing of the rotary encoder, so that touch-sensitivity is provided and light is allowed to exit the shaft and such that the device can be provided as a kit of parts or form part of a mixing console.

A push type switch includes a mounting base, a depressing module, a base board including at least a contact portion, a lighting module, a terminal group, and at least a conductive element. The depressing module includes a cap and a connecting peg movably connected to the mounting base. The cap has a light-permeable side portion spaced apart from the mounting base to form an interval. The lighting module includes a flat flexible cable and a plurality of lighting elements located at the interval. When the depressing module is being pushed to depress and deform the at least a conductive element to enable the conductive element to electrically contact the contact portion, the terminal group transmits electrical signals to allow the plurality of lighting elements to light with multiple lighting modes.

A control mechanism comprises a housing defining an interior and an exterior, an aperture formed in the housing and extending from the interior to the exterior thereof, an actuator on the interior of the housing, proximate the control aperture, and a control member positionable within the aperture to operate the actuator. The control member comprises a first surface exposed to the exterior of the housing, a second surface proximate the actuator within the housing, and a body portion extending therebetween, the body portion being formed of a substantially single crystal aluminum oxide material. A bias member is configured to bias the body portion of the control member toward an inner surface of the housing, such that the control member is retained within the aperture in operation of the actuator.

A key structure includes, from top to bottom in sequence: at least one key main body, made of light transmissible material; a key frame, adapted to mount the key main body; an elastic supporting portion, allowing the key main bodies to move back and forth vertically; at least one bump, formed on one side of the elastic supporting portion; a detection module, sensing the action of the key main body and allowing the bump to be in touch therewith selectively; and a display screen, configured on one side of the detection module. A user can see the bottom display screen through the key main body directly, and the elastic supporting portion drives the bumps to move downward to touch the detection module after the user presses the key main body down. Whereby, the applicable range of the present invention is increased by changing the contents of the display screen.

An actuator is allowed to move toward +A direction and toward −A direction. A movable contact engages with the actuator. A fixed contact touch the movable contact with electrical connection when the movable contact is located at an ON position, and are apart from the movable contact with electrical isolation when the movable contact is located at positions other than the ON position. An arc prevention mechanism prevents arc between the movable contact and the fixed contact.

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.

A system and method for enabling a person with very limited motor and verbal skills to communicate with another person. The system has a pair of spring-loaded buttons having a switch and a contact surface that is pushed by the person to send a contact signal to a controller unit to convert the contact signal into an indication signal. The indication signal is sent to an display to display a message in response to the selected movement of the person's head.

The present invention provides a button structure and a manufacturing method thereof. The button structure includes a base made from a first material, a graphic piece made from a second material, and a transparent piece made from a third material, where the graphic piece is integrally formed with the base and protrudes out beyond an upper surface of the base, the transparent piece wraps the base and the graphic piece, and a heat resistance temperature of the first material and a heat resistance temperature of the second material are both higher than a heat resistance temperature of the third material. In addition, the present invention further provides a game controller using the button structure.
