The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0058] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0059] like Figure 1-9 As shown, an electric switch and a distribution box in one embodiment of the present invention include a gear assembly 1, a light emitting assembly 2 and a rotating body 3; the rotating body 3 includes a bottom shell 31 and a top cover 32, and the top cover 32 can be rotatably mounted on the bottom shell 31; the bottom shell 31 is provided with a connecting through hole 3111, and a hollow column 321 is provided on the side of the top cover 32 opposite to the bottom shell 31; the gear assembly 1 is provided with a rotating shaft 11, and the rotating shaft 11 passes through the connecting through hole 3111 and is fixedly connected to the hollow column 321; the hollow column 321 is sleeved with a mounting support 21, and the mounting support 21 is fixedly connected to the bottom shell 31, and the light emitting assembly 2 is fixedly mounted between the mounting support 21 and the bottom shell 31; the rotation of the rotating shaft 11 causes the gear assembly 1 to form a plurality of gears, and the light emitting assembly 2 is provided with light emitting elements 22 corresponding to the number of the gears, and the light emitting elements 22 are electrically connected to the gears.

[0060] In the present invention, the top cover 32 can be rotatably installed on the bottom shell 31, and the rotating shaft 11 of the gear assembly 1 is fixedly connected to the bottom shell 31. By rotating the top cover 32, the rotating shaft 11 rotates synchronously, so that the gear assembly 1 can be in different gears. The multiple light-emitting elements 22 correspond to the multiple gears one by one and are electrically connected, so that when the gear assembly 1 is rotated to the corresponding gear, the light-emitting element 22 emits light accordingly to achieve the effect of gear visualization. The light-emitting assembly 2 emits light accordingly according to the gear position of the gear assembly 1, so that the light-emitting element 22 can remain lit as needed, thereby protecting the light-emitting element 22 and improving the service life of the light-emitting assembly 2; at the same time, when the above-mentioned power switch is applied to the distribution box 4, the power switch can adjust the gear assembly 1 to the corresponding gear according to the use requirements of the distribution box 4, and functionally adjust the switch of the distribution box 4, thereby improving the practicality of the power switch and the distribution box 4.

[0061] Specifically, the shaft 11 passes through the connecting hole 3111 and extends into the hollow column 321. The shaft 11 and the hollow column 321 are fixedly connected by connecting members such as screws. It is worth noting that the connection between the shaft 11 and the hollow column 321 can also be bonding, etc.

[0062] In one embodiment, the mounting support 21 includes a mounting base plate 211 and a mounting side plate 212, and the mounting side plate 212 is arranged around the mounting base plate 211; the top cover 32 includes a top plate 322 and a first side plate 323, and the first side plate 323 is arranged around the top plate 322; a mounting groove 3221 is provided on the side of the top plate 322 opposite to the mounting support 21, and the mounting side plate 212 can be rotatably installed in the mounting groove 3221; the light-emitting component 2 is installed between the mounting base plate 211 and the top plate 322, and the top plate 322 is made of transparent material.

[0063] Since the mounting support plate is fixedly connected to the bottom shell 31, the mounting side plate 212 remains stationary during the rotation of the top cover 32. As the top cover 32 rotates, the mounting groove 3221 rotates along the mounting side plate 212, guiding the rotation of the top cover 32, thereby making the rotation of the top cover 32 stable and reliable. In addition, the light-emitting component 2 is installed between the mounting bottom plate 211 and the top plate 322, and the top plate 322 is made of a transparent material, so that the light generated by the light-emitting component 2 can be timely transmitted through the top plate 322, achieving the effect of visualizing the shift switch. It is worth noting that a plurality of light-emitting elements 22 are evenly distributed along the circumference of the mounting bottom plate 211, and different light-emitting elements 22 can use different light-emitting colors, thereby improving the visualization effect of the shift switch. The light-emitting element 22 is an LED light string group, and each LED light string group is connected in parallel with at least two LED lamps, so that when one of the LED lamps is damaged, it will not have a significant impact on the light emission of the shift switch.

[0064] Specifically, in order to facilitate the control of the light emitting element over the light emitting switch, in one embodiment of the present invention, the light emitting element is also provided with a current detection circuit, which is connected to the working circuit. The working circuit is the circuit of the gear component 1 that controls the light emitting element 22 to emit light. A current switching module is provided at the output end of the current detection circuit. When the current detection circuit detects that the working LED lamp is malfunctioning, the current switching module switches the current of the working circuit to another LED lamp, so that the LED lamp string group can smoothly switch the LED lamps between different circuits.

[0065] Specifically, the current detection circuit records the current value of the LED lamp during normal operation. By comparing the working current of the LED lamp during operation with the current value, it is determined whether the LED lamp has a fault, so that the current switching module can switch the current of the working circuit accordingly.

[0066] In order to further improve the rotation stability of the top cover 32, in one embodiment of the present invention, the bottom shell 31 includes a bottom plate 311 and a second side plate 312, and the second side plate 312 is arranged around the bottom plate 311; the second side plate 312 is provided with a guide groove 3121 on the side around it, and the first side plate 323 is provided with a guide block 3231 on the side opposite to the second side plate 312; as the top cover 32 rotates, the guide block 3231 can be movably installed in the guide groove 3121.

[0067] In one embodiment, the base plate 311 also includes a first through groove 3112 and a first sleeve column 3113; a second through groove 2111 is provided at a position opposite to the first through groove 3112 of the mounting base plate 211, and the first through groove 3112 is communicated with the second through groove 2111, which serves to limit the wires used for the electrical connection between the light-emitting component 2 and the gear component 1; a second sleeve column 2112 is provided at a position opposite to the first sleeve column 3113 of the mounting base plate 211, and the second sleeve column 2112 is installed on the first sleeve column 3113, so that the mounting support 21 and the bottom shell 31 are fixedly connected.

[0069] Specifically, the rotation of the rotating shaft 11 causes the protrusion 111 on the rotating shaft 11 to trigger the moving contact piece 12 accordingly. When the protrusion 111 triggers the corresponding moving contact piece 12, the second moving contact 1231 is disconnected from the static contact 1313, so that the gear assembly 1 is in the corresponding gear position; it is worth noting that the protrusion 111 is fixed to the circumferential outer side of the rotating shaft 11, and the length and number of the protrusions 111 located above the same moving contact piece 12 are determined according to the requirements of different gear positions, so that the protrusion 111 can trigger the moving contact piece 12 in sequence in a specified order as the rotating shaft 11 rotates. In addition, the number of contact mounting plates 131 on the static contact piece 13 is one, two or three, so that the gear assembly 1 can form different circuit combinations, so that the gear assembly 1 is in different gear positions.

[0070] The contact mounting plate 131 of the static contact piece 13 on the side where the first moving contact 1221 is located is used to fix the first moving contact 1221, so that the moving contact piece 12 will not get loose during the triggering process, so that the triggering of the gear position of the gear assembly 1 is stable and reliable. The contact mounting plate 131 of the static contact piece 13 on the side where the second moving contact 1231 is located is used to fix the static contact 1313, and the static contact 1313 can be connected with the second moving contact 1231 to achieve circuit conduction.

Specifically, the shape of the first movable contact 1221 is adapted to the contact mounting groove 1311, and the first movable contact 1221 can be stuck in the contact mounting groove 1311, so as to limit and fix the movable contact piece 12; the second movable contact 1231 is fixed to the second mounting portion 123, and the second movable contact 1231 is used to trigger the static contact 1313. As the rotating shaft 11 rotates, the protrusion 111 abuts against the abutment portion 121, and at this time, the second movable contact 1231 is disconnected from the static contact 1313.

[0073] Specifically, Figure 5 As shown, an elastic member 1222 is provided below the first mounting portion 122, and the elastic member 1222 is located between the first moving contact 1221 and the abutting portion 121, and the elastic member 1222 has a buffering effect on the triggering of the moving contact piece 12 by the protrusion 111. In addition, the abutting portion 121 includes a first bend 1211 and a second bend 1212 connected to each other, and the extension direction of the second bend 1212 is toward the first mounting portion 122.

[0074] In one embodiment, the shift assembly 1 also includes an installation base 14, and the installation base 14 includes a base bottom plate 141 and two base side plates 142, and the two base side plates 142 are respectively located at the two ends of the base bottom plate 141; the two base side plates 142 are both provided with a base through hole 1421, and the rotating shaft 11 is mounted on the two base through holes 1421; the rotating shaft 11 is also provided with a clamping portion 112, and the clamping portion 112 is clamped between the base side plate 142 and the bottom plate 311. When the power switch is applied to the distribution box 4, the clamping portion 112 is clamped to the box wall of the distribution box 4, which plays a role in limiting the installation of the power switch.

[0075] Specifically, the diameter of the clamping portion 112 is larger than the diameters of the base through hole 1421 and the connecting through hole 3111 . When the rotating shaft 11 is installed in the base through hole 1421 , the clamping portion 112 is located between the mounting base 14 and the rotating body 3 .
