US Patent 7507920 Hearing aid with a control element

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.
