A system and method which provide a keyboard with keys which are configured using a viscoelasticity model. More specifically, with the viscoelasticity model at least certain keys within the keyboard include an elastic component and a viscous component. The elastic component provides a component force which occurs substantially immediately upon application of a stress to the key and relaxes substantially immediately upon release of the stress from the key. In this way the elastic component functions similarly to a spring in a mechanical dashpot model key. The viscous component provides a component force which grows with time as long as a stress is applied to the key. In this way, the viscous component functions similarly to a dash in a mechanical dashpot model key. |

A keyboard includes a main board and at least one key structure positioned on the main board. The key structure includes a key switch and a key cap. The key cap is combined with the key switch. The key switch includes a key base and a shaft movably positioned on the key base. The keycap includes a main body and a cushion member. The main body is positioned on the shaft of the key switch. The main body is spaced apart from the contact surface of the key base. The main body is moved forward and backward relative to the key base with movement of the shaft. The cushion member is positioned at one side of the main body facing the contact surface. While the main body is moved to the contact surface, the cushion member abuts on the contact surface, so as to avoid the main body from hitting the key base directly, and hence minimizing the noise that is produced by the moving parts. |

There is provided a switch including a case, fixed electrodes provided in the case, a movable electrodes and a pressing member. The movable electrode is provided in the case, and is displaced between a first position where the fixed electrodes are electrically connected to each other and a second position where the fixed electrodes are insulated from each other. The pressing member displaces the movable electrode from the second position to the first position when a pressing force from outside is applied to the pressing member. The pressing member is elastically deformed by the pressing force so that a contact area between the pressing member and the movable electrode is increased. |

This invention provides novel keyboards comprising keys disposed such that they minimize the distance a finger typically must travel to effect a keystroke and the force that is applied to effect a keystroke. Accordingly the keyboards require less arm and finger movement to and thereby reduce the likelihood of an operator developing a repetitive stress injury (RSI). In one embodiment the keyboards comprise a plurality of keys disposed such that the alphanumeric keys form a continuous key array defining a key array surface having at least two concave regions wherein a plurality of keys present irregular and/or non-rectilinear striking faces. |

A foil-type switching element includes a first carrier foil and a second carrier foil arranged at a distance from each other by means of a spacer, the spacer including at least one recess defining an active area of the switching element. At least two electrodes are arranged in the active area of the switching element between the first and second carrier foils in such a way that, in response to a pressure acting on the active area of the switching element, the first and second carrier foils are pressed together against the reaction force of the elastic carrier foils and an electrical contact is established between the at least two electrodes. At least one of the first and second carrier foils includes a multi-layered configuration with an inner supporting foil and an outer elastic activation layer, the outer elastic activation layer being deformable in response to pressure acting thereon in such a way that the outer elastic activation layer presents a greater thickness in a central region of the active area than in a peripheral region of the active area, and thereby presses the inner supporting foil towards the other carrier foil in said the central region. |

A buffering protective handheld controller, mainly with a buffering protective configuration for direction button and a number of functional buttons on one side of the main unit. The user is allowed to have greater touch area and more comfortability when pressing the button. In addition, under a long period of button-pressing time, the user has finger contact with surrounding buffering devices to reduce pressure. It composes a multiple-layer cushion as a protective mechanism. Further, the handheld main unit has the rigid plastic base in an appropriate hollow shape, which may be enclosed by a sticking soft pad with a proper size. Thus, it can provide a cushion air-bag effect and fits the user's palm in any shape and any size. Particularly, because the user can hold the unit with a firm grasp by fingers, the grasping force is minimized during use. |

A key switch wherein a key top 1 made of thermoplastic resin and a extruding part 2 made of thermoplastic elastomer are integrally formed, thereby improving clicking touch of a contact member, such as a metal belleville spring, a resin film dome or the like, which is placed underneath the extruding part and preventing breakage and laceration of the contact member. Further, a key switch is constructed such that extruding parts 2 of a plurality of key tops 1 are integrally linked by means of a U-shaped bridging member 3 made of thermoplastic elastomer, thereby causing elastic deformation of the bridging member 3 at the time of pressing one of the plurality of key tops 1 so that an extruding part 2 of an adjacent key top is prevented from operating together. |
