A luminous keyboard includes plural key structures, a switch circuit board, a supporting plate, a backlight module and plural ring-shaped structures. The switch circuit board is located under the keycaps of the key structures. The supporting plate is located under the switch circuit board and connected with the key structures. The backlight module is located under the supporting plate. The backlight module generates a light beam. The plural ring-shaped structure are disposed on the switch circuit board and arranged around the corresponding key structures. When the light beam is reflected by the key structures, the light beam is received by the plural ring-shaped structure. Due to the material properties of the ring-shaped structures, the periphery regions of the keycaps generate a uniform luminous effect.

A switch according to the present invention includes a base including a recessed portion on one surface of the base; a click spring having a dome shape, the click spring being provided at the recessed portion such that the bottom of the recessed portion is contacted at a dome-shaped opening side of the click spring; a cover provided to cover the recessed portion and to house the click spring at the recessed portion; and a strain detecting element attached to another surface of the base. The strain detecting element is configured to detect strain of the base, the strain occurring in accordance with a depression amount of the click spring that is depressed.

A key switch implements a receiving switch conductor and transmitting switch conductor in the key switch. Depressing the key switch will cause the receiving switch conductor and transmitting switch conductor to approach each other. The approach of a finger and movement of the key switch can be detected using the receiving switch conductor and the transmitting switch conductor.

The subject matter of this specification describes a method that includes determining when to send a user selection of a first key on a keyboard to an operating system, where the operating system supports shortcut key combinations. The device identifies the user selection of the first key, as input for an application. The device determines that the first key is part of a shortcut key combination. The processing device determines whether a cursor is visible in a user interface provided by the application. Upon determining that the cursor is visible in the user interface, the device waits for another user selection of one or more remaining keys of the shortcut key combinations before sending the first key to the operating system. Upon determining that the cursor is not visible in the user interface, the device sends the first key to the operating system without waiting for another user selection.

An input device includes a structural frame, a touch pad, a piezoelectric sheet fixed on the touch pad, and a controller electrically connected to the touch pad and the piezoelectric sheet. The touch pad has a first side, a second side opposite to the first side, and a touch-sensitive surface that has a button area located at the second side. The touch pad can be elastically deflected to move the second side relative to the structural frame. The piezoelectric sheet generates a voltage when the touch pad is elastically deflected. When determining that a press is performed on the button area and the voltage is larger than or equal to a corresponding predetermined value, the controller sends out a trigger signal. An electronic apparatus with the input device includes a display screen and a processor. The processor receives the trigger signal to control the display screen to display images.
