Problems solved by technology
If the fuse burns out, because the knife switch itself does not have an alarm function, people cannot know whether the fuse is blown, and cannot replace the fuse in time; and if it needs to be replaced, the wiring screw must be unscrewed before the fuse can be replaced, which is cumbersome , The knife switch itself does not come with a redundant fuse, so it cannot be used in an emergency

The invention relates to an alarming knife switch convenient to replace a fuse. Red copper tongue pieces of a middle terminal and an exit terminal both form fixed orifices, and movable binding posts respectively pass through the fixed orifices on an outlet terminal and the middle terminal; the movable binding post on the outlet terminal is mutually parallel to the movable binding post on the corresponding middle terminal; nuts are arranged on studs of each movable binding post; a spring is sheathed on the movable binding post body and is arranged between a spacing flange and the red copper tongue piece; the movable binding post body of any wiring terminal is provided with a fuse orifice vertical to the axis thereof, the movable binding post body of the corresponding outlet terminal is provided with a fuse inclined trough corresponding to the fuse orifice; and one end of the fuse passes through the fuse orifice, and the other end is horizontally arranged in the fuse inclined trough. Fuses can be replaced by manual operation in no need of any tools, and the knife switch has the alarming function.
Description
technical field [0001] The invention relates to an electrical switch, in particular to an alarm knife switch which is convenient for replacing a fuse. Background technique [0002] The knife switch is generally composed of a knife handle, a blade, a base, a switch cover, an input terminal, an output terminal, a neutral terminal, and a fuse on both sides of the base. The terminal is composed of copper tongue and terminal screw, the intermediate terminal is composed of copper tongue, intermediate clip and terminal screw, the shape of the fuse is S type, and the two ends of the fuse are respectively connected to the outgoing terminal and the medium terminal through terminal screws . If the fuse burns out, because the knife switch itself does not have an alarm function, people cannot know whether the fuse is blown, and cannot replace the fuse in time; and if it needs to be replaced, the wiring screw must be unscrewed before the fuse can be replaced, which is cumbersome , The k...
