Abstract
A top structure for a keypad, comprising a number of key caps. The structure comprises a solid flexible layer, which is placed above the key caps or directly on them, and arranged to yield when the key is felt. The material, properties and thickness of the flexible layer are selected so that the key cap can be perceived by a sensation of touch and found under the layer, when the key is felt. The flexible layer is, for example, of a textile or textile-imitating material. The top structure can be utilized in a keypad component, in an electronic device, particularly a mobile phone, and in clothing provided with a keypad.
