Open/Closed Indicating Apparatus For Circuit Breaker Operating Apparatus
Abstract: An open/closed indicating apparatus for a circuit breaker operating apparatus, comprising a button (1) and an indicating element (2). The button (1) is provided therein with a cavity (101). The indicating element (2) is mounted within the cavity (101). The indicating element (2) can rotate within the cavity (101). The button (1) is provided thereon with an observation window (102). The indicating element (2) can display different areas in the observation window (102) while rotating. When a small number of gaps are provided between the indicating element (2) and the housing (3), the impact on the angle of rotation of the indicating element (2) is reduced, the indicating element (2) can accurately indicate an open/closed state of a circuit breaker, and when a product is being fitted and assembled, a requirement on gap fitness is reduced for the assembly. When the indicating element (2) is in a free state, a mesa (4) on the housing (3) presses the indicating element (2) to a correct position, thus increasing the production efficiency.
