Claims

[Claims for Utility Model Registration] (1) A mechanism main shaft that is rotationally driven by an electric motor and stores energy via a tension spring, and one end that rotates due to the displacement of a cam plate attached to this mechanism main shaft. an elastic body attached to the lower part of the emission indicator near the display area, and a switch that is operated via the elastic body to open and close the power source of the electric motor. The motor circuit switching mechanism of the constructed electric spring-operated circuit breaker. (2) Claims for registration of a utility model in which an emission indicator is provided with a display part at one end of an arm part having a letter-shaped cross section and a roller that engages with a cam plate at the other end. 2. A motor circuit switching mechanism for the electric spring-operated circuit breaker according to item 1. (3) A motor circuit switching mechanism for an electric spring-operated circuit breaker as set forth in claim 1 of the registered utility model, in which the center of rotation of the emission indicator is biased toward the cam plate side.
