  • Patent number: 7394911
    Abstract: An interchangeable hearing aid control panel with at least one activation zone arranged in connection with a layered structure. The layered structure has an electrically non-conducting substrate, an electrically conducting path arranged in connection with the substrate, and an electrically conducting member, such as a conducting foil, arranged at a predetermined distance from the activation zone. The activation zone can be either in a deactuated or in an actuated state. In the actuated state the conducting member and the conducting path are electrically connected while disconnected in the deactuated state. Electrical connection to an associated hearing aid is by means of a connector, such as a plug, enabling the control panel to be easily changed. Preferably, the connector is formed by a piece of flexprint. The layered structure may comprise a second conducting path. In preferred embodiments activation zones are indicated by “poppel domes” formed by a surface layer covering the layered structure.
