Abstract
In the case of a hearing aid with a movable control element as compact a structure as possible should be achieved and at the same time a large number of movement cycles of the control element should be possible. To this end it is proposed to connect contacts of the movable control element by means of a flexible PCB to the PCB. Preferably the flexible PCB also acts as a support for a flat spring-loaded switch which is activated when the control element performs a swivel movement. Furthermore the flexible PCB has a bending zone which is devoid of electrical contacts and components.

A hearing aid, comprising:
- a source transducer to receive an input signal and to convert it into an electrical input signal;
- a signal processing unit to process the electrical input signal;
- and
- a load transducer to convert the processed electrical input signal into an output signal that can be perceived by a user and making it possible to adjust the signal processing unit by a user-activated control element, the control element having electrical contacts and being capable of being rotated about a first axis and swiveled about a second axis and a plurality of electrical components of the signal processing unit being arranged on a PCB and a flexible PCB being provided to connect the electrical contacts of the control element and of the PCB.
