摘要

The arrangement with functional components for a button accordion involves the tones of the Swedish-Italian, Norwegian-Dutch, Finnish button method or the old Russian Bajan method arranged by transposition of the tone tongues (15) to the keyboard bodies (3). The key bearings are formed as triple-staged, axial axis-less rocker bearings (17). The keyboard (4), keyboard wires (5) and the valve plates (6) comprise parts produced preferably by an original shape technique.
