Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0020] Reference Figure 1A switch for visually identifying status includes a protective cap 16 and a housing 8 snapped under the protective cap 16. From top to bottom, the two are arranged with a handle 11, a slide bar 3 and a sleeve 9. A contact ring 2 is horizontally inserted at the bottom end of the sleeve 9. A base 1 is arranged at a certain distance below the sleeve 9. A conductive post 21 is arranged on the base 1 and is located directly below the contact ring 2.

[0021] A diaphragm 15 is provided on the contact surface between the slide bar 3 and the handle 11. A pin 12 is provided below the diaphragm 15. The pin 12 passes through the slide bar 3, the sleeve 9 and the spring 13 in sequence, and its bottom end is provided on the base 1.

[0022] The slide bar 3 and the handle sleeve 10 are fixedly connected by an interference fit; the handle 11 and the handle sleeve 10 are connected by a threaded connection, ensuring that the handle 11 is detachable and that all three move synchronously. The handle 11 and the handle sleeve 10 press against each other, pressing the diaphragm 15 to prevent it from shifting. The outer shell 8, the handle sleeve 10, and the second sealing ring 7 press against each other to achieve an internal sealing function, further improving the switch's environmental resistance. The outer shell 8, the protective cap 16, and the outer waterproof ring 5 press against each other to achieve an external sealing function, further improving the switch's environmental resistance. The protective cap 16 and the outer shell 8 can be quickly separated.

[0023] A red marking is designed in the center of the diaphragm 15 as a warning. The center holes of the slide bar 3 and the handle 11 are aligned, allowing the state of the red marking on the diaphragm 15 to be observed through the holes. The tail end of the ejector pin 12 is fixed to the base 1, and its tip inserts into the hole of the handle sleeve 10, aligning with the center of the diaphragm. The tip can penetrate the diaphragm, and the diameter of the ejector pin is larger than the red marking on the diaphragm, completely destroying the marking. After the ejector pin penetrates the diaphragm 15, the damaged state of the red marking on the diaphragm 15 can be observed through the through hole of the handle 11.

[0024] The contact ring 2 passes through the inner hole of the sleeve 9 and can move freely within the sleeve 9. A spring 13 is designed on the upper end face of the contact ring 2, and the other end of the spring 13 is fixed to the contact point between the slide rod 3 and the sleeve 9. The spring 13 plays a role in straightening the contact ring 2 and provides contact pressure to ensure reliable electrical contact. The conductive post 21 is embedded in the base 1 by a mold, further saving internal space. The end of the conductive post 1 has a spherical design to increase the pressure between the contact pairs and ensure reliable contact.

[0025] The outer casing 8 is threaded and installed using a nut for fixation; the threads of the outer casing 8 are milled flat to prevent the switch from rotating and effectively improve the operability of the switch. The outer casing 8 adopts a "three-claw structure" for riveting, which can ensure the safety indicators such as dielectric withstand voltage and insulation resistance between the outer casing 8 and the conductive post, while preventing the base 1 from rotating relative to the outer casing 8 and from detaching. A beaded chain assembly 20 is provided at the top of the protective cap 16 to connect with the outer casing 8. Below the outer casing 8, a washer 18, a first sealing ring 6, an internal toothed elastic washer 19, and a hexagonal nut 17 are arranged in sequence to prevent the protective cap 16 from being lost.

[0026] By pressing the handle 11, the sleeve 9, spring 14, and contact ring 2 are pushed downwards, compressing the spring 13 to store energy. When the displacement reaches a certain position, the tip of the ejector pin 12 punctures the diaphragm 15, and the handle 11 continues to move downwards, connecting the contact ring 2 with the conductive post, thus turning on the switch. Further downward movement compresses the spring, ensuring reliable contact. When the external force is removed, the spring 13's restoring force pushes the sleeve 9, handle 11, and contact ring 2 upwards. When the contact ring 2 reaches a certain position, it disconnects from the conductive post, turning off the switch. Further upward movement causes the tip of the ejector pin to detach from the diaphragm, returning the switch to its initial position.

[0027] The foregoing has provided a detailed description of the visual recognition status switch provided by this utility model. Specific examples have been used to illustrate the structure and working principle of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
