Patent ID: 8304674

Claim:
A signaling device suitable to be operatively coupled to a circuit breaker, comprising: an electrical switch configured to generate an electrical signal indicating a transition of the circuit breaker from a first state to a second state; an actuating mechanism for actuating the electrical switch; a movable body which is pivotally mounted around a first axis so as to interact with the actuating mechanism; and a return spring which is mounted around an axis substantially parallel to said first axis, said return spring operatively connected to said pivoting body which is adapted for assuming a rest position and a pivoting configuration in which said pivoting body rotates to interact with said actuating mechanism, reaches a final position and returns back to said rest position, and wherein said return spring is operatively connected to said pivoting body in such a way that when said pivoting body rotates towards said final position said return spring is subject to a moment of force causing its preloading, said return spring then biasing said pivoting body from said final position to said rest position.
