A keyboard-key biasing device 10 having a resiliently-flexible body element 12, a resiliently-flexible elongate first biasing member 14 which has a first contact area 30 and a resiliently-flexible elongate second biasing member 16 which has a second contact area 34. The first and second contact areas 30, 34 being at different distances from the body element 12 so that the biasing device 10 is usable in a plurality of orientations to suit a plurality of keyboard configurations

An illuminated keyswitch structure includes a base plate, a keycap, and a light-emitting die package. The keycap is movably disposed above the base plate in a vertical direction. The light-emitting die package is disposed under the keycap and includes a plurality of light-emitting dies. The plurality of light-emitting dies are monochromatic light-emitting dies. Therein, among the plurality of light-emitting dies, three light-emitting dies that are adjacently arranged in an arrangement direction perpendicular to the vertical direction emit light of three different colors. The arrangement direction is respectively parallel to along side of each of the three adjacent light-emitting dies.

The present invention address the problem of providing a push-button switch which is capable of clearly displaying an image output from a display and which allows a person performing a depressing operation to have a distinct operational feel. Among the elements constituting the push-button switch, a button is a transparent or substantially transparent button which is disposed over a display and which receives a depressing operation. Lenses are disposed between the button and the display, and cause an image output from the display to be projected with a focal point at a diffusing plate in a top surface of the button in a standby position before a depressing operation is performed. A holding member incorporates the lenses in such a way that the position and orientation of each of the lenses are fixed with respect to the display. Thus, the problem is solved.

A trigger assembly for a power tool includes a housing, a moveable plunger extending from a surface of the housing, the movable plunger includes a first end disposed externally from the housing and a second end disposed internally within the housing. The trigger assembly further includes a trigger shoe coupled to the first end of the moveable plunger, and an arm including a first side that is moveably connected to the second end of the moveably plunger and a second side that is coupled to a magnet. The trigger assembly also includes a sensor configured to sense a magnetic field of the magnet. Movement of the trigger shoe rotates the magnet, and alters the magnetic field sensed by the sensor.

A keyboard key device includes a keycap and a substrate unit. The substrate unit includes a light-emitting component, a light guide plate, and a light transmission plate. The light guide plate has first and second end surfaces, and at least one light-condensing hole. The first end surface is formed with an uneven microstructure for diffuse reflection of light rays. The light transmission plate has first and second side surfaces, and an outer reflective layer coated on the second side surface. A portion of light rays emitted from the light-emitting component and into the light transmission plate pass through the outer reflective layer, and the remainder of the light rays are reflected by the outer reflective layer.
