[0007] a light source component, which is placed below the mounting panel and adjacent to the switch seat, and has a socket; and

[0008] An optical fiber group extends from the socket of the light source component through the panel optical fiber perforation, the screw sleeve perforation and the button switch perforation in sequence to the top surface of the button switch. The light source component is used to illuminate the optical fiber group.

[0009] As a preferred solution of the lighting structure of a toggle switch handle, a switch cap body is disposed on the top of the toggle switch, and a light-transmitting portion is formed on the switch cap body.

[0010] Compared with the prior art, the beneficial effects of the present invention are at least as follows: the toggle switch is used to realize the handle lighting function, which is convenient for pilots to identify the switch handle position at night, and the structure is simple, the reliability is high, the maintainability is good, and the maintenance and upgrade of the on-board products can be completed quickly. The overall installation adopts anti-slip screws, the installation and disassembly process is convenient, and parts will not fall off. The solution of direct plug-in with a drop-out plug is adopted, which saves installation and maintenance time. The lighting area of ​​the toggle switch is annular, which improves the recognition speed of the switch at any position.

[0011] In addition to the technical problems solved by the present invention, the technical features that constitute the technical solution, and the beneficial effects brought about by the technical features of the technical solution described above, other technical problems that can be solved by the present invention, other technical features included in the technical solution, and the beneficial effects brought about by these technical features will be further described in detail in conjunction with the accompanying drawings.

[0018] The present invention is further described in detail below by means of specific embodiments in combination with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] See also Figures 1 to 6 , the figure shows a toggle switch handle lighting structure, which is applied to an aircraft control panel.

[0020] The button switch handle lighting structure is mainly composed of a mounting panel 1, a switch assembly 2, a light source component 4, an optical fiber group 3, a hexagonal nut, an internal tooth washer, an anti-slip screw, a spring washer, a positioning washer, a light guide plate 5 and a support plate 6.

[0021] The installation panel 1 is formed with a panel switch through hole 11 and a panel optical fiber through hole 12 .

[0022] The switch assembly 2 comprises a switch housing 21, a fixing screw sleeve 22 and a button switch 23. The switch housing 21 is placed below the mounting panel 1. The fixing screw sleeve 22 extends upward from the top surface of the switch housing 21 and passes through the panel switch through hole 11. An oblique screw sleeve through hole 220 is formed on the fixing screw sleeve 22 above the mounting panel 1. A vertical button switch through hole 230 is formed on the button switch 23.

[0023] The light source component 4 is placed below the installation panel 1 and adjacent to the switch seat body. The light source component 4 has a socket.

[0024] The optical fiber group 3 extends from the socket of the light source component 4 through the panel optical fiber perforation 12, the screw sleeve perforation 220 and the button switch perforation 230 to the top surface of the button switch 23. The light source component 4 is used to illuminate the optical fiber group 3. The side surface of the optical fiber is shielded to prevent light diffusion, and light is emitted from both end surfaces of the optical fiber.

[0025] The top of the button switch 23 is provided with a switch cap body 24. A light-transmitting portion 240 is formed on the switch cap body 24. The light-transmitting portion 240 is made of a transparent optical material. The middle dot on the top surface of the light-transmitting portion 240 is painted black and does not emit light. The outer edge of the top surface of the light-transmitting portion 240 is painted white in a ring shape for emitting light. A step is provided on the top of the switch cap body 24 for placing the light-transmitting portion 240. An appropriate amount of silicone is applied to the gap between the light-transmitting portion 240 and the step on the top of the switch cap body 24 for installation, waterproofing, and crack prevention.

[0026] After the light source component 4 receives external electricity and lights up, the light is transmitted to the top surface of the button switch 23 through the optical fiber group 3, and the ring-shaped white paint emits light, which is used to identify the position of the switch handle at night. A threaded hole is provided at the bottom of the switch cap body 24, and the handle of the button switch 23 is supplemented and processed into a threaded shape at the top of the handle. A back-cut groove is provided at the bottom of the thread for installing and fixing the switch cap body 24.

[0027] The hexagonal nut and the inner tooth washer are installed above the mounting panel 1 to fix the switch assembly 2 to prevent it from loosening. The positioning washer is installed below the mounting panel 1 to prevent the switch assembly 2 from rotating.

[0028] The step hole of the mounting panel 1 is provided with a threaded hole below, which is used to prevent the anti-slip screws and spring washers from falling off after the anti-slip screws are installed in the early stage and the lighted modified switch is disassembled. Step holes are provided on both sides of the support plate, the size of the hole is larger than the thread size of the anti-slip screw, and threaded holes are provided below the step hole to fix the anti-slip screws.

[0029] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
