  • the shared trip arm 21 acts and thereby causes the trip bolt 22 to trip, this will cause the engagement tip 411 on the first locking rod 40 to disengage from the trip bolt 22. Due to the tripping of the first locking rod 40, as an accumulated spring force is released, the first locking rod 40 moves from the fourth position to the fifth position, and the first rotating plate 50 rotates in an anticlockwise direction. As the position of the first moving contact 51 changes, the circuit state thereof also changes, e.g. switches from the first electrical circuit to the second electrical circuit.
