Abstract
A hearing apparatus includes a charging contact being movable relative to an accumulator and being electrically conductively connected to the accumulator in a first position and less effectively conductively connected thereto in a second position. A spring-elastic element engages with the charging contact in order to push the charging contact into the second position with a predetermined force, so that the charging contact can only be pushed into the first position by overcoming the predetermined force. As a result, the charging contact configuration obtains a switching function, so that electro-corrosion on the charging contacts can be prevented. Therefore, charging an accumulator of a hearing apparatus and in particular of a hearing device using a direct conductive contact is possible, with zero potential of the charging contacts which are accessible from the outside being ensured during normal operation of the hearing apparatus.
