Abstract:
1. A control arrangement for a hearing aid or for a control unit coupled to the hearing aid, said control arrangement receiving, as an input, a mechanical actuating force from a user and generating, in response thereto, an electrical control signal for controlling at least one functionality of the hearing aid or the control unit coupled thereto, the control arrangement comprising: a strain gauge mechanically coupled to an inner surface of an elastically deformable or displaceable portion of the hearing aid or of the control unit coupled thereto and being elastically deformed under the influence of said actuating force, wherein said strain gauge undergoes a variation of at least one of its electrical values dependent from the input of the actuating force; a controller electrically connected to said strain gauge transforming said variation of said at least one of the electrical values of said strain gauge into said electrical control signal by a circuit free of galvanic closing and opening contacts; and an elastically deformable support comprising a cantilever beam with either a battery or a programming connection formed therewith, wherein said strain gauge is provided in or on the elastically deformable support.
