There are provided a keyboard threshold change apparatus and a keyboard in which thresholds of the ON-sensing positions of the keys can be individually changed and the thresholds can be checked with illumination colors.

A keyboard threshold change apparatus includes: a keyboard 1 that includes an illumination LED 17 illuminating key tops of a plurality of keys and a threshold change unit 2 capable of changing, for each key among the keys, a threshold used to determine an occurrence of a press of the key; and a computer 3 that is connected to the keyboard and that includes a mouse 38 used to input the threshold and a display unit 36 outputting the threshold input with the mouse as an image, in which when the threshold for a key among the keys is changed with the mouse, the threshold change unit changes, on the basis of the changed threshold for the key from the computer, a threshold for the key in the keyboard, and the illumination LED changes an illumination color of the key for which the threshold is changed to a color corresponding to the threshold.

An adjustable keyboard includes a driving element, a first plate, a second plate and a plurality of keys. The second plate is disposed between the first plate and the keys, wherein the second plate has a plurality of key openings and the keys are respectively aligned with the key openings. The driving element is configured to drive the first plate to move, and thus a plurality of first guide portions on the first plate respectively push a plurality of second guide portions on the second plate so as to move the second plate and adjust the distance between each of the keys and the corresponding key opening.

A start/stop engine button assembly includes a start/stop engine button, a button cover, displaceable between a closed position and an open position, and an actuator that functions to displace the button cover between the closed position and the opened position.

Aspects of the disclosure relate to a games controller for controlling electronic games, input device for a computer program and a trigger mechanism therefor. The trigger mechanism comprises a trigger body having a plurality of walls defining an internal chamber. The plurality of walls include a base wall and an orifice defined in the base wall. A detent is detachably mounted on the trigger body. The detent is at least partially received in the orifice and the detent is rotatable with respect to the trigger body. The detent comprises at least one abutment surface which is eccentrically arranged with respect to the rotational axis of the detent.

A keypad device includes a circuit board having raised buttons disposed on a first surface of the circuit board, resilient switches disposed on a periphery of the first surface, and through-holes, wherein each of the raised buttons and switches, when actuated, closes a circuit on the circuit board and affects an input to the device. The keypad device includes a faceplate fastened to the circuit board, the faceplate having an array of openings configured to allow the buttons to pass through, bosses extending from a first surface of the faceplate toward the circuit board and positioned to pass through the through-holes on the circuit board, and plungers aligned above and in contact with the resilient switches such that when the plate is pressed toward the circuit board, in a region at or near a subject plunger, the subject plunger actuates the resilient switch that is in contact with the plunger.

A keyboard switch includes a key top movable vertically on receiving a depressing force, a plunger engaged with a lower portion of the key top and movable vertically with the key top, a cup rubber disposed under the plunger and supporting the plunger from below, a housing arranged on an outer peripheral side of the plunger and cup rubber, a plate supported on the housing and extending laterally, and a spacer interposed between the plate and key top. The spacer is removably mounted onto the keyboard.

A keyswitch with adjustable tactile feedback is adjusted by an adjusting method. The keyswitch includes a baseplate, an upper housing, an upper bushing component, a lower bushing component, a keycap and a recovering component. The baseplate has an electrode module, the upper housing is disposed on the baseplate, the upper bushing component is movably disposed on the upper housing, the lower bushing component is movably located between the baseplate and the upper housing, and the keycap is connected to a connecting portion of the upper bushing component. The lower bushing component can rotate relative to the baseplate to switch between a first position and a second position. The lower bushing component has a first lateral surface and a second lateral surface with different shapes. The recovering component is disposed between the baseplate and the lower bushing component to upwardly push the lower bushing component.
