A portable keyboard includes a plurality of key assemblies including a plurality of key tops, a main body of a pillar shape of n angles, which is located in the vicinity of a first key assembly among a plurality of the key assemblies and includes a plurality of sides, a flexible connection member configured to connect a plurality of the key assemblies with the main body, and a main board configured to be embedded in the inside of the main body and process input signals inputted from a plurality of the key assemblies. In this case, the main body includes a first side of which one edge of the first side is connected with the flexible connection member, a second side adjacent to another edge of the first side and the second side of which an angle with the first side is equal to or greater than 90 degrees, and a cradle configured to combine one end of the cradle with the second side using a hinge to make the cradle to be rotated and the cradle configured to be contacted with the second side.

A pushbutton shifter interface is provided on a vehicle and includes a plurality of pushbutton keys arranged horizontally on a dashboard. The pushbutton shifter interface may be fixedly coupled with the dashboard generally forward of a driver seat. The pushbutton shifter interface is accessible by a driver to select a vehicle operating mode.

A keyboard device includes plural keycaps and a membrane switch circuit member. The membrane switch circuit member is disposed under the plural keycaps. The membrane switch circuit member includes a wiring board and plural separate covering pads. The wiring board includes plural first trace patterns and plural second trace patterns corresponding to the plural keycaps. The plural second trace patterns are disposed on the wiring board and separated from the plural first trace patterns. There is a gap between each first trace pattern and the adjacent second trace pattern. The covering pads are disposed over the wiring board. The plural covering pads are aligned with the corresponding keycaps and cover the corresponding gaps. The covering pad has a triggering trace pattern over the corresponding gap.

A keyboard is disclosed. The keyboard includes a keyboard housing and a switch assembly coupled to the keyboard housing. The switch assembly includes a switch body defining an interior volume, a collapsible dome positioned in the interior volume, an actuation member configured to actuate the collapsible dome in response to an actuation of the actuation member, and a cover coupled to the switch body. The cover retains the actuation member to the switch body. The keyboard also includes a flexible material coupled to the keyboard housing and extending over the actuation member.

A keypad for an electronic data-entry device. The keypad includes: a plurality of keys defining a layer of keys; a connection printed-circuit board having a key-press detection portion having an external face oriented towards the layer of keys and an internal face opposite the external face; for each key of the layer of keys, an interconnection element and at least one pair of contacts on the connection printed-circuit board, the interconnection element being intended for making the electrical connection of the contacts of the pair of contacts when the associated key is pressed. The connection printed-circuit board is a flexible printed-circuit board further including a connecting portion forming a fold beneath the internal face of the key-press detection portion, and the pair of contacts is disposed on the internal face.

A keyboard device includes plural key structures, an electronic paper display element and an illumination module. The electronic paper display element is disposed under the plural key structures. The plural key symbols corresponding to the plural key structures are displayed on the electronic paper display element. The illumination module is disposed over the electronic paper display element to provide a light beam to the electronic paper display element. Consequently, the plural key symbols are illuminated.

A keyboard device includes a key switch, a base plate, a connecting element and a replaceable key. The replaceable key includes a coupling plate and a keycap. The connecting element is connected between the coupling plate and the base plate. The coupling plate includes a first sliding part. The keycap includes a second sliding part. When the second sliding part is slid relative to the first sliding part, the keycap is combined with the coupling plate or the keycap is detached from the coupling plate. Consequently, the keycap is easily assembled or disassembled. Moreover, since the connecting element is not touched during the process of disassembling the keycap, the connecting element is not damaged.
