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.

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.

A rotary switch structure includes a sleeve, a seat body, an elastic ring, plural push elements and a fixing element. The seat body is accommodated within the sleeve. The elastic ring is disposed on the seat body. The plural push elements are disposed on the elastic ring, and provide a pushing force to the elastic ring. The fixing element is fixed in the sleeve and contacted with the plural push elements. The plural push elements are fixed on the elastic ring by the fixing element. The elastic ring absorbs the pushing force, so that a friction force between the at least one push element and the elastic ring is adjustable. Consequently, the rotating feel of the rotary switch structure is adjustable according to the practical requirements.

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.

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 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. The apparatus includes a keyboard having a light illuminating key tops of a plurality of keys and a threshold change unit capable of changing, for each key, a threshold used to determine an occurrence of a press of the key; and a computer connected to the keyboard including a mouse to input the threshold and a display unit outputting the threshold input with the mouse as an image, when the threshold for a key is changed with the mouse, the threshold change unit changes, based on the changed threshold for the key from the computer, a threshold for the key in the keyboard, and the light changes an illumination color of the key for which the threshold is changed.

A control device includes an upper actuator panel, a lower support frame relative to which the upper panel is mounted to be mobile vertically, an electric switch the body of which is carried by the upper panel, and a set of two arms for actuating the electric switch. Each arm of the set includes a distal section that bears against a portion of the upper panel, a proximal section that bears on the actuator of the electric switch, and an intermediate section that bears against a portion of the lower frame and about which each actuator arm is mounted to pivot. The actuator arms cooperate with the upper panel and the lower frame to maintain the upper panel horizontal during its movement relative to the lower support frame.

This disclosure describes various configurations for a keyboard having multiple key assemblies. Each of the key assemblies includes a keycap and a key stem supporting the keycap that includes a protrusion extending laterally therefrom. A first biasing member supports the key stem and is configured to provide a linear feedback response during actuation of the key assembly. A second biasing member is configured to engage the protrusion during actuation of the key assembly. The second biasing member has a user-configurable feedback response. In some embodiments, the first biasing member can be a compression spring and the second biasing member can be a torsion spring.

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.
