Abstract: In a control arrangement for hearing aids or for control units coupled to hearing aids, a strain gauge is mechanically coupled to an elastically deformable or displaceable portion of the hearing aid or of the control unit coupled thereto and undergoes an elastic deformation under the influence of an actuating force input by a user, whereby the strain gauge undergoes a variation of one of its electrical values which variation is detected by a controller which provides a control signal which serves for switching between different operation modes of the hearing aid or of the control unit coupled to the hearing aid.

Abstract: The invention is directed to a hearing aid device that includes a housing having an opening and a battery drawer. The opening and the battery drawer are parts of a battery door that is rotatably mounted to the housing. The battery drawer also includes a finger engagement portion arranged at the outside surface of the battery drawer. The battery door can be closed by pushing the finger engagement portion, and maintained in a closed state. The battery door can be at least partly opened by pushing the finger engagement portion, and maintained in an at least partly open state. The hearing aid device can be electrically switched on and off by pushing the finger engagement portion.
