Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0033] Example 1:

[0034] This embodiment provides a disconnect switch with status display, including:

[0035] The face cover assembly includes a face cover body 1, a display window 2 on the face cover body 1, a slider 3 that is slidably disposed along the Z direction, and a handle for driving the slider 3 to move, and a drive rod 11 on the slider 3;

[0036] 4. Outer shell;

[0037] The linkage component is driven by the movement of slider 3;

[0038] The indicator slide plate 8 is driven by the drive rod 11 and is slidably disposed in the slide groove 15 on the inner surface of the faceplate body 1 along the Z direction and is correspondingly disposed at the position of the display window 2. An elastic element is provided on one side of the indicator slide plate 8, and a protrusion 12 is provided on the surface of the elastic element. At least two grooves 13 on one side of the slide groove 15 cooperate with the protrusion 12.

[0039] When slider 3 slides, protrusion 12 moves into different grooves 13.

[0040] The faceplate assembly includes a faceplate body 1, a display window 2 on the faceplate body 1, and a slider 3 that slides along the Z direction as shown in the figure. The faceplate body 1 has a groove for slidingly mounting the slider 3. The slider 3 passes through the groove and is connected to a linkage component. A handle is rotatably mounted on the faceplate body 1 and drives the slider 3 to rotate. Alternatively, a disc with an open-edge groove can be mounted on the handle, and a sliding rod on the slider 3 that slides in conjunction with the groove on the disc can be used to drive the slider 3 to slide. The outer shell 4 is the main body for mounting the linkage component. The linkage component achieves the closing and opening actions through the sliding drive of the slider 3. The specific structure is not described in detail. An indicator slide plate 8 is driven by a drive rod 11 on the slider 3. The indicator slide plate 8 slides along the Z direction within a groove 15 on the inner surface of the faceplate body 1, and is correspondingly positioned in the display window. At position 2, the color of the indicator slide plate 8 can be observed through display window 2. The indicator slide plate 8 is divided into two color areas, usually set as red and green. An elastic element is provided on one side of the indicator slide plate 8. This elastic element can be formed on the indicator slide plate 8, such as a through hole on one side of the indicator slide plate 8 to form a thin-walled elastic element. A protrusion 12 is provided on the surface of the elastic element. At least two grooves 13 that can cooperate with the protrusion 12 are provided on one side wall of the slide groove 15. When the slider 3 slides, the indicator slide plate 8 is pushed by the up and down swing of the drive rod 11. When the protrusion 12 is dislodged from the groove 13, the elastic element is compressed. When the protrusion 12 moves into another groove 13, the elastic element returns to its original state, and the protrusion 12 is locked in the groove 13, thereby fixing the position of the indicator slide plate 8. The color of the indicator slide plate 8 can be observed through display window 2. Each position corresponds to a color and a working state.

[0041] The above structure enables the display of the working status of the disconnect switch, and it is simple to install and has a stable working status.

[0042] Example 2:

[0043] This embodiment provides a disconnecting switch with status display, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] The linkage components include:

[0045] Terminal block 5 includes several contact blades 6;

[0046] The moving contact assembly includes contact portions 7 having the same number of contact blades 6 as the contact points 6, and is rotatably disposed within the housing 4;

[0047] Elastic member 9 is used to connect the edge of the moving contact assembly to the slider 3.

[0048] Terminal 5 is used to connect wires (live and neutral wires). The blade 6 is the stationary contact. The moving contact assembly is rotatably disposed inside the housing 4. The moving contact assembly includes the same number of contact parts 7 as the blade 6. When the moving contact assembly rotates, the contact parts 7 can contact the blade 6 to realize the connection of the circuit. The elastic member 9 is an energy storage mechanism used to connect the moving contact assembly and the slider 3.

[0049] Example 3:

[0050] This embodiment provides a disconnecting switch with status display, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] The indicator slide plate 8 is provided with a stop bar 10, and a drive rod 11 is provided between the stop bars 10. When the protrusion 12 needs to move from one groove 13 to another groove 13, the drive rod 11 abuts against and moves the stop bar 10, and the width between the stop bars 10 is greater than the distance between the two grooves 13.

[0052] A stop lever 10 is provided on the back of the indicator slide plate 8. The drive rod 11 is placed between the two stop levers 10. When the protrusion 12 needs to move from one groove 13 to another groove 13, the drive rod 11 abuts against and pushes the moving stop lever 10, causing the stop lever 10 to move. The distance between the stop levers 10 is greater than the distance between the two grooves 13. The sliding distance of the slider 3 is controlled by the distance between the stop levers 10, which can increase the moving distance of the slider 3. The stop lever 10 is pushed only when the circuit is closed or opened. Increasing the moving distance makes it easier for the slider 3 to drive the linkage component.
