1. A plug-in circuit breaker comprising a circuit breaker housing and an operating button, one end of said operating button inserted inside the circuit breaker housing being a button inner end, and the other end of said operating button protruding outside the circuit breaker housing being a button outer end;
wherein an indicator slot is arranged inside said operating button, an indicating hole is arranged on said button outer end, and said indicating hole communicates with said indicator slot; the plug-in circuit breaker further includes an indicating member, one end of which is provided with a make-contact indicating surface and a break-contact indicating surface both respectively fitting with said indicating hole;
when the plug-in circuit breaker is in a break-contact state, said break-contact indicating surface is arranged opposite to said indicating hole, thus during pressing said operating button to move it toward the make-contact position, said indicating member moves inside said indicator slot, after the plug-in circuit breaker enters the make-contact state, said make-contact indicating surface is arranged opposite to said indicating hole, thus during pulling said operating button to move it toward the break-contact position, said indicating member moves inside said indicator slot, after the plug-in circuit breaker enters the break-contact state, said break-contact indicating surface is arranged opposite to said indicating hole.
