ABSTRACT:
A horn operating means has two contact plates separated from each other by a resilient foam sheet. For contacting, one of the contact plates is deformed by the operating force so much that it will touch the other contact plate. In one embodiment, grooves in the central region of one of the contact plates provide for the necessary operating forces not being greater in the central region than in the edge region.
