A circuit interrupter with an accessory case socket into which an accessory bell alarm member is disposed. A two-piece lever arrangement is provided in the bell alarm accessory case between the micro-switch button thereof and the operating mechanism of the circuit breaker. In the first stage of operation the operating mechanism rotates the entire two-piece member as a unit until the bell alarm button has been completely depressed, after which overtravel of the operating mechanism is accommodated by rotational movement of only one of the members on a common axis against the force of a hub located torsion spring.

La présente invention concerne un interrupteur de circuit ayant un élément de connexion à boîtier auxiliaire dans lequel se trouve un élément d'alarme à sonnerie auxiliaire. Un système de levier en deux parties se trouve dans le boîtier auxiliaire l'alarme à sonnerie entre le bouton de microcommutateur dudit boîtier et le mécanisme de fonctionnement de l'interrupteur de circuit. Dans la première étape de fonctionnement, le mécanisme de fonctionnement fait tourner la totalité de l'élément en deux parties jusqu'à ce que le bouton d'alarme à sonnerie soit complètement enfoncé, puis la course excédentaire du mécanisme de fonctionnement est ajustée par mouvement rotationnel de seulement l'un des éléments sur un axe commun en direction opposée de la force exercée par un ressort de torsion se trouvant au niveau du moyeu.
