Opening/closing indicating apparatus for circuit breaker operating apparatus

Abstract

An open/closed indicating apparatus for a circuit breaker operating apparatus, comprising a button and an indicating element. The button is provided therein with a cavity. The indicating element is mounted within the cavity. The indicating element can rotate within the cavity. The button is provided thereon with an observation window. The indicating element can display different areas in the observation window while rotating. When a small number of gaps are provided between the indicating element and the housing, the impact on the angle of rotation of the indicating element is reduced, the indicating element 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.
