Abstract: An electrical hearing aid adapter is provided. The electrical hearing aid adapter may be configured to transfer programming data to a hearing aid having a first end portion formed in such a manner that it corresponds to the shape of a battery compartment receiving chamber being configured to receive a hearing aid battery compartment. The electrical hearing adapter may further include an interface configured to receive programming data and to transfer received programming data to an electrical contact portion arranged on the first end portion. The first electrical contact portion may be arranged such that it electrically contacts to a second electrical contact portion placed in the battery compartment receiving chamber, when the first end portion is inserted into the battery compartment receiving chamber.

Abstract: An electrical circuit has a printed circuit board which is lengthened at the side in the form of at least one longitudinal contact projection having at least one electrical conductor track and a solder point disposed at the end of the conductor track. Because of its mechanical flexibility, the contact projection allows flexible contact to be made with other electronic components, with little effort. An electrical circuit such as this is particularly highly suitable for electrical small appliances, in particular for a hearing aid.
