Abstract
L'invention concerne l'horlogerie. Certaines des palettes d'une pendule à palettes comportent des saillies 61 avec lesquelles une pièce de contact de detection 38 peut venir en contact de façon à détecter avec précision le changement des minutes qui correspond à un instant de déclenchement de sonnerie réglé à l'avance. Pour éviter d'imposer une charge permanente au moteur 1, la pièce de contact 38 ne vient en contact avec la saillie correspondante que très peu de temps avant l'instant de déclenchement fixé. Application aux pendules à palettes.
