A cover structure for a keypad
Abstract
A top structure for a keypad, comprising a number of key caps (9). The structure (1, 24) comprises a solid flexible layer (7) which is placed above the key caps (9) or directly on them, and arranged to yield when the key (9) is felt. The material, properties and thickness of the flexible layer (9) are selected so that the key cap (9) can be perceived by a sensation of touch and found under the layer (7), when the key (9) is felt. The flexible layer (7) 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.
