  • Publication number: 20220384133
    Abstract: A plug-in circuit breaker with an operating button that includes a button inner end inserted inside the circuit breaker and a button outer end. An indicator slot is arranged inside the operating button, an indicating hole is arranged on the button outer end. The plug-in circuit breaker further includes an indicating member slidably inserted inside the indicator slot and one end of which is provided with a make-contact indicating surface and a break-contact indicating surface. When the plug-in circuit breaker is in a break-contact state, the break-contact indicating surface is arranged opposite to the indicating hole, thus during pressing the operating button, the indicating member moves inside the indicator slot. After the make-contact state, the make-contact indicating surface is arranged opposite to the indicating hole. The indicating member is arranged inside the operating button to save space and to indicate the break-contact and make-contact state through the indicating hole.

  • Patent number: 9384930
    Abstract: A fuse appliance has a fuse carrier for receiving a fuse and a base. The fuse carrier is in a cavity of the base and is manually operable to remove or insert the fuse. Fixed contacts are provided on the base which engage with moving contacts provided on the carrier. Wiring terminals are electrically connected to the fixed contacts. A rotational-linear pulling operation mechanism has a semicircular rotary shaft structure that has two semicircular convex shafts and first and second circular straight grooves fitted to each other so that the fuse carrier performs rotational and linear movements relative to the base and an interchange between rotational and linear movements at a transition position when the carrier is pulled out of or pushed into the appliance.
