The transparent cover 7 may be made of plastic. The structure of the earth leakage protection module 3 is prior art and will not be described here.
The mechanical indicator 4 comprises an indicator plate 41 and a compression spring 42. A groove-shaped indicator board mounting frame 21 is arranged on the base 2, the opening of the groove-shaped indicator board mounting frame 21 faces the rod part 51 of the reset key 5, and a limiting protrusion 211 is arranged on one side of the top end of the groove-shaped indicator board mounting frame, which is close to the reset key 5. The indicating plate 41 may include a top plate 411, a bottom plate 412, and a straight plate 413 connecting the top plate 411 and the bottom plate 412. Preferably, the index plate 41 is integrally injection molded from plastic or the like. The top plate 411 includes a first indication portion 4111 and a second indication portion 4112, and a first mark and a second mark are respectively provided on surfaces of the first indication portion 4111 and the second indication portion 4112, and the first mark and the second mark are respectively used for indicating that the leakage current switch is in a closed state and an open state. The juncture between the first indicating portion 4111 and the second indicating portion 4112 protrudes to both sides to form a stopper portion, and the top plate 411 is movably supported on the top end of the slot type indicator plate mounting bracket 21, and the stopper portion is engaged with the stopper protrusion 211, so that the first indicating portion 4111 or the second indicating portion 4112 of the top plate 411 is positioned in the indicator window 11. The bottom plate 412 is movably supported on the top surface (specifically, the wiring board) of the earth leakage protection module 4. The side of the straight plate 413 facing the groove type indicator plate mounting frame 21 is provided with a spring fixing part 4131, and the other side is matched with the reset key 5. One end of the compression spring 42 is fixed to the spring fixing portion 4131 and the other end abuts against the slot-type indicating plate mounting bracket 21, so that when the reset key 5 is ejected, the second mark (the second indicating portion 4112) is displayed in the indicating window 11, as shown in fig. 1 and 2; and when the reset key 5 is pressed, the first mark (first indicating portion 4111) is displayed in the indicating window 11.
In the present embodiment, a slot-type indicator board mounting bracket 21 is formed on a side surface of the base 2. This can simplify the structural design of the base 2 and reduce the cost.
In this embodiment, the end of the bottom plate 412 has an extension 414 opposite to the straight plate 413, and the extension 414 is used for cooperating with the side of the earth leakage protection module 3 to prevent the indicator plate 41 from being jacked up by the compression spring 42 when the reset key 5 is ejected.
In this embodiment, the connecting portion between the straight plate 413 and the top plate 411 is an inclined surface, and the bottom of the reset key 5 is provided with an inclined portion 52 engaged with the inclined surface. This kind of structure is favorable to the cooperation of reset key 5 and indicator plate 41 on the one hand, and on the other hand can reduce the friction between reset key 5 and the indicator plate 41, makes the activity of reset key 5 more smooth.
