Abstract:
1. A hearing aid multifunctional switch, comprising a base part, an externally activable switch arm, a first and a second set of contact surfaces disposed at a surface of said base part, the first set of contact surfaces being adjacently positioned so as to form a substantially continuous surface, the second set of electrically isolated contact surfaces being adjacently positioned so as to form a substantially continuous surface, the second set of contact surfaces being oppositely arranged to said first set so that the two sets have pairs of corresponding contact surfaces, a contact member movable between said pairs of contact surfaces for providing electrical contact between a pair of corresponding contact surfaces, and a pressure pad, wherein at least part of said pressure pad is positioned between a resilient member and the contact member, the pressure pad being biased by the resilient member against the contact member, wherein the resilient member and the pressure pads are positioned within a hollow space within the switch arm so that the resilient member and the pressure pad are integrated within said switch arm.
