A keyboard switch comprises an upper cover (1), a base (2), a fixed terminal (3), a movable terminal (4) and a pressing component (5). A guide column (21) is disposed on the base, the pressing component is installed on the guide column on which a return spring (8) is fitted, the upper end of the pressing component is exposed out of the upper cover for pressing, and the upper cover is fastened to the base to form a cavity, the fixed terminal and the movable terminal are disposed on one side of the pressing component in the cavity, and one end of the fixed terminal and one end of the movable terminal penetrate out of the base to be connected to an external circuit. The pressing component moves up and down to drive the movable terminal to move, and further to control contact and disconnection between the other end of the movable terminal and the other end of the fixed terminal. Further, an elastic auxiliary component for interfering with the pressing component to enhance the pressing sense is disposed on the other side of the pressing component, and the pressing component interferes with the elastic auxiliary component while moving up and down to drive the movable terminal. The keyboard switch makes full use of the inner space of the switch and an auxiliary device is added in the switch, so that the switch has good touch and voice, a simple structure and a long life.

The present description relates to devices, such as keyboards. One example can include a top portion and an opposing bottom portion and key switches that are mechanically retained in holes formed in the top cover. The example can also include electrical traces formed on the top cover that extend from the holes to a processing unit that is configured to receive electrical signals along the electrical traces when the key switches are closed.

A thin switch includes a pressing cup (1), a base (2) and a top cover (3). A conductive component (4), a spring (5), a fixed terminal (6) and an elastic wire (7) are disposed in a space defined by buckling the base and the top cover. The elastic wire is arranged below the conductive component, one end of the elastic wire is fixed on the base and the other end is disposed under a boss of the pressing cup. When the pressing cup is pressed down, the conductive component is driven to contact the fixed terminal to turn on the switch, and the elastic wire is driven to descend at the same time. When the pressing cup is pressed down to a preset position, the elastic wire separates from the pressing cup, and bounces back upwards to strike the dome to make a sound.

A keyswitch structure includes a baseplate having a switch opening, a keycap movably disposed above the baseplate, a circuit board disposed on the baseplate, the circuit board having a through hole, and a mechanical switch disposed below the keycap, the mechanical switch extending through the through hole to be partially received in the switch opening and electrically coupled to the circuit board, wherein when the keycap moves toward the baseplate, the keycap triggers the mechanical switch.

A dome switch utilized in a keyboard assembly is disclosed. The keyboard assembly may include a printed circuit board having a first electrical connector formed in the printed circuit board, and a second electrical connector formed in the printed circuit board adjacent the first electrical connector. The keyboard assembly may also include an inner contact component contacting the second electrical connector of the printed circuit board. The inner contact component may be in electrical communication with the second electrical connector of the printed circuit board. Additionally, the keyboard assembly can include a dome switch surrounding the inner contact component. The dome switch may contact and may be in electrical communication with the first electrical connector of the printed circuit board.

According to one embodiment, there is provided an input apparatus comprising a key that is displaceable along a direction; a first detecting circuit that comprises an electrostatic capacitance sensor that detects a variation of an electrostatic capacitance caused by a contact or a proximity of a pressing body with the key; and a second detecting circuit that comprises a first electrode, the second detecting circuit detecting an electric connection of the first electrode to a second electrode that is displaced along the direction as the key is displaced, wherein the input apparatus switches a detecting status thereof exclusively between a first detecting status and a second detecting status to each other in accordance with a displacement variation of the key.

A control switch includes a key, a housing structure, in the upper portion of which the key is secured in a manner such that the key can rotate about a first fulcrum. A tip is secured at one end to the key and moving integrally therewith, so as to slide along a first axis (X) of the key is countered by an elastic element. A printed circuit board includes at least two push-buttons, arranged in the lower portion of the housing structure. The housing structure includes in its internal portion, a flared structure having two inclined contact planes specularly opposite with respect to a second vertical axis (Z) and forming a first obtuse angle (a), on which the tip can slide along its stroke. The flared structure is structurally secured to the housing structure. The switch includes at least one actuator positioned in proximity to the flared structure.

A portable electronic user device, in the form of an electronic key, having an inherently rigid button for activation by a user. The portable electronic user device further has a flexibly deformable membrane including a first side having at least one support section on which the at least one button is supported via the plunger, and an actuating section, separate from the at least one support section, for receiving and forwarding an actuation of the button to an electrical switch element. There is a rigid frame which bears the membrane on a second side opposite the first side, wherein, in the assembled state, having the membrane in the region of the at least one support section, the frame has at least one breakout, via which the membrane is moveable by the plunger upon activating the at least one button and, in dependence on the size and/or the shape of the breakout, provides a force for resetting the button. As a result of the separation of the generating of the reset force on the support sections movable by the first breakouts and the switch function in the region of the activation section, there is great freedom in the design of the portable electronic user device, wherein reliable triggering of the switch element is always ensured.
