Battery contact for a hearing device

摘要

The device has a contact spring (4) for contacting a positive terminal (2) of a battery (1), and a spiral contact (5) for contacting a negative terminal (3) of the battery. The spiral contact is formed in a partial section as induction coil through which current supplied by the battery is derived. A contact area is arranged in the center of the coil for contacting the negative terminal of the battery, where contact forces are exerted on the terminals of the battery by the contacts. An independent claim is also included for a voltage supply device for a hearing aid.
