<P>PROBLEM TO BE SOLVED: To provide a trip button mechanism of an externally-operable handle for a circuit breaker. <P>SOLUTION: An embodiment of the present invention provides a trip button mechanism of an externally-operable handle for a circuit breaker which operates a circuit breaker trip button arranged on the circuit breaker. The trip button mechanism includes: a button support which is disposed on an outer casing of the externally-operable handle and is communicated to the outside via a penetration hole formed on the outer casing; an externally-operable trip button including a handle which is exposed through the penetration hole, and a pusher which is formed integrally with the handle and moves along the button support for selectively pushing the circuit breaker trip button; and an elastic member for applying force to the externally-operable trip button in a direction opposite to a direction in which the externally-operable trip button pushes the circuit breaker trip button. According to the embodiment of the present invention, easiness in an assembly process and reliability in an operational phase can be ensured, and enhancement in productivity and reduction in cost can be expected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
