ABSTRACT:
A miniature hearing aid has data storage components, amplification components, and a hinged battery compartment in which a battery may be disposed. A latch, in conjunction with a switch, allows for a selection of the operational mode of the hearing aid by positioning the hinged battery compartment at various angles to the hearing aid housing. The battery is held firmly in the battery compartment in the various switching positions by a contact spring, which also serves as the electrical connection between the battery and various electrical component groups housed within the hearing aid. The battery can be disconnected from the amplification components while remaining connected to the data storage components.
