    • An input device comprises a support plate and a cover plate. The cover plate has an upper surface facing away from the support plate and a lower surface facing towards the support plate, and includes a capacitive sensing arrangement associated with an input zone for capacitively detecting position and/or movement of a user's finger or stylus. One or more spacers arranged at the periphery of the input zone mount the cover plate on the support plate in such a way that the cover plate spans over the support plate in the input zone. The cover plate is designed with a rigidity such that a user may depress it towards the support plate in the input zone. The input device comprises a pressure-responsive switch associated with the cover plate and the support plate. The pressure-responsive switch includes at least one first electric circuit element arranged on the lower surface of the cover plate and at least one second electric circuit element arranged on the support plate in facing relationship with the at least one first electric circuit element in such a way that the at least one first electric circuit element and the at least one second electric circuit element can be brought into contact when the cover plate is depressed towards the support plate. The rigidity of the cover plate is such that, with increasing force acting on the first surface in direction of the support plate, a physical contact zone develops initially at a defined central point of the input zone and then gradually extends towards the periphery of the input zone and the at least one first electric circuit element and the at least one second electric circuit element of the pressure-responsive switch are arranged in such a way that an electrical contact is only established if the physical contact zone exceeds a predefined radius around the central point of the input zone.
    • 输入装置包括支撑板和盖板。 盖板具有背向支撑板的上表面和面向支撑板的下表面,并且包括与用于电容地检测使用者的手指或触针的位置和/或移动的输入区相关联的电容感测装置。 布置在输入区域周边的一个或多个间隔件将盖板安装在支撑板上,使得盖板跨过输入区域中的支撑板。 盖板被设计成刚性,使得使用者可以将其朝向输入区域中的支撑板压下。 输入装置包括与盖板和支撑板相关联的压力响应开关。 所述压力响应开关包括布置在所述盖板的下表面上的至少一个第一电路元件和布置在所述支撑板上的至少一个第二电路元件,所述至少一个第二电路元件与所述至少一个第一电路元件面对关系, 当盖板朝向支撑板压下时,使得至少一个第一电路元件和至少一个第二电路元件可以接触的方式。 盖板的刚性使得随着在支撑板的方向上作用在第一表面上的力的增加的力,物理接触区域最初在输入区域的限定的中心点处形成,然后朝着输入的周边逐渐延伸 区域,并且压力响应开关的至少一个第一电路元件和至少一个第二电路元件被布置成仅当物理接触区域超过围绕中心的预定义半径时才建立电接触 输入区域的点。

    • A 5-directional key operation device capable of operating five diaphragms with one button, wherein diaphragm contacts loaded with the diaphragms (4) disposed in a crossshape in conformity with a 5-directional keys are formed of a first contact (1) and a second contact (2) surrounding the first contact (1) and having band-shaped contacts (3a to 3b) installed extendedly on the opposite side of the first contact, whereby an installation space for the diaphragm contacts can be reduced, and the size and weight of the entire device can be reduced; five pusher parts (126) being installed on a key core surface opposed to the five diaphragms on a printed circuit board of a key base (127).
    • 一种能够利用一个按钮操作五个隔膜的五方向键操作装置,其中装载有与五方向键一致的横截面的隔膜(4)的隔膜触点由第一触点(1)和第二触点 接触(2)围绕第一接触件(1)并且具有延伸安装在第一接触件的相对侧上的带状接触件(3a至3b),由此可以减小隔膜接触件的安装空间,并且其尺寸和重量 的整个设备可以减少; 五个推动器部件(126)安装在与键座(127)的印刷电路板上的与五个隔膜相对的键芯表面上。
