A key structure includes a movable element, an elastic element, a light-emitting element and a pressure sensing element. The pressure sensing element is arranged between the elastic element and the light-emitting element. The elastic element is disposed on the movable element. The light-emitting element emits a light beam. The light beam is transmitted through the pressure sensing element and projected to the movable element to illuminate the key structure. While the key structure is depressed, the elastic element is pushed by the movable element. The pressure sensing element is pushed by the elastic element according to different magnitudes of the depressing force. Consequently, the key structure generates different pressure sensing signals.

An appliance has an operating unit with an actuating element for triggering a pre-determined action. The actuating element is mechanically actuatable by force of a user. The actuating element is preferably a mechanically actuatable switch and/or key element. A touch-sensitive sensor is built into the actuating element, for detecting skin contact occurring as a result of the exertion of force for the mechanical actuation of the actuating element. The appliance is also embodied in such a way that, as a requirement for triggering the pre-determined actions, it is checked whether the actuating element is actuated and skin contact is detected by the touch-sensitive sensor. The appliance prevents defective actuations by associating touch-sensitive sensor technology with the mechanically actuatable actuating element. This ensures that mechanical actuation without skin contact does trigger the pre-determined action.

For a remote controller that is mainly used for simply and surely controlling various electronic devices, when predetermined pressing force is imposed on an operating body, a predetermined set value is stored in a storing section when a detection value of a pressure-sensitive conducting contact exceeds a predetermined resistance value and the detected value is stored in the storing section when the detection value of the contact point is within the range of the predetermined resistance value. Since a remote control signal is generated using a ratio of a value stored in the storing section and a value obtained when the remote controller is operated, an electronic device can be controlled without being influenced by variation of elements constituting the remote controller.

Provided is an input device which has excellent operability by not requiring a finger to be released from a key during operation requiring the finger to shift and preventing the finger from touching a plurality of keys at the same time. A key (12) surrounding a selection key (18) is arranged. On a board (41), four metal domes (14) are arranged at positions corresponding to the four positions, i.e., upper, lower, right and left positions, of the key (12). A touch sensor (13) is arranged on an upper layer above the metal dome (14). The touch sensor (13) is brought into contact with a touch sensor presser (53), and an electrical value (for instance, a resistance value) is changed corresponding to shift of the finger on the key (12). When the key (12) is strongly pressed down, the top of the metal dome (14) is pressed into the substrate (41) side and electricity is carried between contact points (14a, 14b).

An interdigital electronic device comprises a conductor, an interdigital electrode, and a composite material disposed between the conductor and the interdigital electrode for electrically connecting the conductor and the interdigital electrode under application of sufficient pressure therebetween. The composite material comprises conductive particles at least partially embedded in an electrically insulating layer. The conductive particles have no relative orientation and are disposed so that substantially all electrical connections made between the conductor and the interdigital electrode are in the z direction. At least one of the conductor and the interdigital electrode is movable toward the other.

An input device contains a resistance-element series formed by series-connected resistance elements, low resistors opposing the resistance elements, an operating object which brings one of the low resistors into contact with one of the resistance elements and changes the contact area therebetween, an output point at the midpoint between resistance elements, and a controller. When the resistance element and low resistor are not in contact, the input device enters a sleep mode in which the resistance-element series or low resistors have a high potential and the other a low potential. In the sleep mode, determination that the operating object has been operated occurs when a change in voltage or current on the low potential side is detected. A voltage is applied across ends of the resistance-element series, and the device enters a detection mode in which the output is based on the contact area change.

The aim of the invention is to develop a keyboard for compact mobile electronic appliances, said keyboard comprising an integrated signal detection element and enabling simple data input and simultaneous continuous control possibilities using a plurality of keys; an electronic inquiry mechanism for actuating the keys; and an evaluation method for a momentary key position during the continuous actuation of individual keys. To this end, keys which are applied in a mobile manner and provided with a spring suspension are mechanically coupled, on the lower side thereof, to a continuous strip conductor extending over at least one key and having a high electrical resistance, such that when the keys are actuated, the strip conductor comes into contact with another strip conductor, in the actuation position, said other strip conductor extending over all of the keys and having a low electrical resistance, and an analog-digital converter AD0 determines the electrical resistance or voltage drop between the strip conductor and an end of the strip conductor, said measuring value being unequivocally associated with a defined key and the actuation position on said key.

Switches SW1 to SW4 and variable resistors are formed so as to overlap each other at positions corresponding to the X-axial positive direction, the X-axial negative direction, the Y-axial positive direction, and the Y-axial negative direction, respectively. When at least one of the switches SW1 to SW4 is off, no Z-axial output is activated and only X- and Y-axial outputs are activated. On the other hand, when any of the switches SW1 to SW4 is on, no X- and Y-axial outputs are activated and only a Z-axial output is activated.
