Abstract: The present invention relates to a hearing aid multifunctional switch comprising a base part, an externally activable switch arm, and a first and a second set of contact surfaces disposed at a surface of said base part. The first set of contact surfaces is adjacently positioned so as to form a substantially continuous surface, whereas the second set of electrically isolated contact surfaces is adjacently positioned so as to form a substantially continuous surface. The second set of contact surfaces is oppositely arranged to said first set so that the two sets have pairs of corresponding contact surfaces. A contact member is movable between said pairs of contact surfaces for providing electrical contact between a pair of corresponding contact surfaces.
Abstract: A battery holder for a microelectronic device, said holder comprising a frame having a substantially circular base and a curved portion with an upper and a lower surface. The curved portion encloses at least part of the substantially circular base, and the frame is adapted to hold a battery. A first conductor extends from a first part of the curved portion to a second part of the curved portion, and wherein a first end of the first conductor is positioned within the first part of the curved portion and wherein a second end of the first conductor is positioned within the second part of the curved portion. A movable member is positioned on the curved portion and adapted to provide an electrical connection between the second end of the first conductor and a point of contact within the second part of the curved portion.
