    • A pressure-responsive touchpad is provided with a touch-sensitive area, wherein the position of an actuator exerting a compressive force on the touch-sensitive area can be detected. The touchpad comprises a first sheet member and a second sheet member arranged at a certain distance from each other by a spacer, the spacer delimiting the touch-sensitive area, a first resistive electrode arranged in the touch-sensitive area on the first sheet member and a second resistive electrode arranged in the touch-sensitive area on the second sheet member in facing relationship with the first resistive electrode, in such a way that, in response to the compressive force acting on the touch-sensitive area, the first and second sheet members are pressed together whereby a contact area is formed and an electrical contact is established in the contact area between the at least first and second resistive electrodes. The touchpad comprises at least one light source and/or reflective element arranged underneath the first and second sheet members with respect to the direction of the compressive force. The first and second resistive electrodes are substantially intransparent for light coming from the at least one light source and/or reflective element, and the first and second electrodes, respectively, have at least one opening associated with the at least one light source and/or reflective element for allowing light to pass from the at least one light source and/or reflective element through the touch-sensitive area.
    • 压力响应触摸板设置有触敏区域,其中可以检测到在触敏区域施加压缩力的致动器的位置。 触摸板包括第一片状构件和第二片状构件,该第一片状构件和第二片状构件通过间隔物彼此隔开一定距离,限定触敏区域的隔离物,布置在第一片状构件的触敏区域中的第一电阻电极和 第二电阻电极,其布置在与第一电阻电极相对的第二片状部件上的触敏区域中,使得响应于作用在触敏区域上的压缩力,第一和第二片材 构件被压在一起,由此形成接触区域,并且在至少第一和第二电阻电极之间的接触区域中建立电接触。 触摸板包括相对于压缩力的方向布置在第一和第二片状构件下方的至少一个光源和/或反射元件。 第一和第二电阻电极对于来自至少一个光源和/或反射元件的光基本上是不透明的,并且第一和第二电极分别具有与至少一个光源相关联的至少一个开口和/或 反射元件,用于允许光从至少一个光源和/或反射元件通过触敏区域通过。

    • A foil-type switching element comprises a first carrier foil and a second carrier foil arranged at a certain distance by means of an inner spacer. The inner spacer comprises at least one cut-out defining an active area of said switching element where at least two electrode structures are arranged between said first and second carrier foil so as to define at least one pair of spaced switch contacts. According to the invention, the switching element further comprises a first outer spacer layer, said first outer spacer layer being arranged on an outer surface of said first carrier foil and said first outer spacer layer comprising at least one opening in the region of said active area. In a preferred embodiment of the invention, the foil-type switching element further comprises a second outer spacer layer, said second outer spacer layer being arranged on an outer surface of said second carrier foil and said second outer spacer layer comprising at least one opening in the region of said active area.
