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. A pressure pad, wherein at least part of said pressure pad is positioned between a resilient member and the contact member, is biased by the resilient member against the contact member so as to ensure continuous contact between the contact surfaces and the contact member.
