The beneficial effect of above-mentioned structure is: be provided with divide-shut brake indicating mechanism in the base, this divide-shut brake mechanism can realize the function of a plurality of signal indication, be favorable to improving the reliability of this divide-shut brake mechanism work, and this divide-shut brake mechanism structural design is simple, the pilot lever moves along with the pivot, can insert in the pilot hole of upper cover, the user can audio-visually learn the operating condition of circuit breaker, and be provided with the pulley on the lower extreme of pilot lever, can avoid pilot lever and pivot when the transmission, the card is dead each other, be favorable to improving this divide-shut brake mechanism job stabilization nature. Therefore, the plastic case leakage circuit breaker has the advantages of simple structure, reliable performance, small volume and high safety.
Particularly, the indication rod is provided with a lug corresponding to the two micro switches respectively, and each lug acts along with the indication rod and forms linkage fit of the indication rod and the two micro switches. The indicating rod and the two micro switches are in linkage fit, so that the opening and closing indicating mechanism has multiple signal indicating functions, and the reliability of the operation of the opening and closing indicating mechanism is improved.
Particularly, the reset spring is sleeved on the indicating rod, one end of the reset spring is abutted to the limiting groove in the support, and the other end of the reset spring is abutted to the limiting step of the indicating rod. The reset spring is clamped between the indicating rod and the support, so that the opening and closing indicating mechanism is convenient to assemble, and the assembly efficiency of the residual current circuit breaker is improved.
