[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention discloses a signal light with a press-and-rotate combination switch function, such as... Figure 1 As shown, the assembly includes a combination handle, a light source component, a band switch assembly, and a push-button switch assembly arranged sequentially from top to bottom. The combination handle includes a knob 3 and a button 1. The knob 3 is attached to the outside of the outer shaft 4. The knob 3 and the outer shaft 4 rotate synchronously in the circumferential direction to realize rotation operation.

[0034] The outer shaft 4 has a central through hole with an inner shaft 7, and the button 1 is connected to the outside of the inner shaft 7, such as... Figure 3 As shown, button 1 is located inside knob 3. Button 1 and inner shaft 7 move synchronously along the axial direction to realize the pressing operation.

[0035] The knob 3 is fitted with an outer bushing 28, and the button 1 is fitted with an inner bushing 29. The mating sections of the outer bushing 28 and the inner bushing 29 with the outer shaft 4 and the inner shaft 7 are all D-shaped, and the outer bushing 28 and the inner bushing 29 are fixed to the outer shaft 4 and the inner shaft 7 respectively by the set screw 2.

[0036] Both button 1 and knob 3 are made of light-transmitting polymer material, and characters are provided on the upper part of button 1.

[0037] like Figure 2 and Figure 4 As shown, the light source component includes a light source base 24 with two threaded holes, which serve as the mechanical interface of the present invention. A light source printed circuit board 25 is provided on the upper part of the light source base 24. Two wires are connected to the light source printed circuit board 25, which extends out of the light source base 24 as the electrical interface of the light source component. These wires can be connected to the switch's own circuit to realize the lighting function when pressed or rotated, or they can be controlled by external logic signals. An LED light source 26 is provided on the light source printed circuit board 25. The LED light source 26 illuminates the characters of button 1 from the bottom surface of the combination handle. LEDs of different colors can be installed as needed, and the brightness of the LEDs can be adjusted by adjusting the resistor.

[0038] A light source cover 6 is provided above the light source base 24. The light source base 24 and the light source cover 6 are connected by threads. A light-transmitting cover 27 or an optical sheet can be installed in the middle layer between the light source base 24 and the light source cover 6 to play the roles of light transmission, protection, light filtering and diffusion.

[0039] The upper part of the outer shaft 4 is provided with an annular groove, and a retaining ring 5 is provided at the annular groove. The retaining ring 5 is stopped by the top of the light source seat 24 to restrict the axial movement of the outer shaft 4. The lower part of the outer shaft 4 is provided with an annular boss, and the annular boss is restricted from moving upward by the step on the inner wall of the light source seat 24.

[0040] like Figure 2 and Figure 5As shown, the band switch assembly includes a rotary positioning mechanism and a circuit switching mechanism. The rotary positioning mechanism includes a rotary positioning seat 22, a spring fixing block 20, a spring 23, and a sliding member 21. Both the rotary positioning mechanism and the circuit switching mechanism are driven by an outer shaft 4. The lower end of the outer shaft 4 is fixedly provided with a first convex shaft and a second convex shaft, which are spaced apart vertically.

[0041] The spring fixing block 20 is installed on the first convex shaft. The spring fixing block 20 has a mounting hole along the radial direction. The mounting hole is fitted with a spring 23 and a sliding member 21. The inner wall of the rotating positioning seat 22 has an equally divided arc boss along the circumference. When the outer shaft 4 rotates, it drives the sliding member 21 to slide along the surface of the arc boss. The connection of the arc boss is recessed with a groove. The groove can accommodate the sliding member 21 to slide in, which plays a role in positioning and indexing.

[0042] The circuit conversion mechanism includes a terminal block 10, a moving contact fixing seat 18, a moving contact component 11, a stationary contact 12, a common terminal piece 9, and a terminal block 19. The moving contact component 11 is located inside the terminal block 10. The second convex shaft is fixedly connected to the moving contact component 11 through the moving contact fixing seat 18. The upper end of the moving contact component 11 contacts the common terminal piece 9, and the common terminal piece 9 is fixed to the upper end of the terminal block 10.

[0043] The lower end of the terminal block 10 is provided with several stationary contacts 12. The outer shaft 4 and the moving contact component 11 rotate synchronously. When the outer shaft 4 rotates, the sliding member 21 enters a positioning groove, and the same moving contact component 11 corresponds to a different stationary contact 12, realizing circuit switching between different stationary contacts 12.

[0044] The terminal block is provided with terminal 19, such as Figure 5 As shown, the outer sides of the terminal block 19 and the common terminal piece 9 both protrude from the outer wall of the terminal block 10, and the terminal block 19 and the common terminal piece 9 serve as electrical interfaces.

[0045] like Figure 2 and Figure 6 As shown, the push-button switch assembly includes a switch base 14, a pressure plate 17, and several microswitches 16. The upper part of the switch base 14 is radially widened and has an annular step. The pressure plate 17 is located at the upper end of the annular step. The lower end of the inner shaft 7 is fixed to the upper end of the pressure plate 17 by a threaded connection. The microswitches 16 are located at the lower part of the switch base 14 and are fixedly connected to the switch base 14 by rivets 15. The rivets 15 penetrate the lower part of the switch base 14 radially. When the inner shaft 7 presses down, it drives the pressure plate 17 to press and trigger multiple microswitches 16 inside, realizing the conversion and conduction of multiple signals. A square boss is provided below the inner shaft 7, which cooperates with the square hole of the cover 13 to prevent rotation and limit upward movement.

[0046] like Figure 2As shown, the light source component, band switch assembly, and push-button switch assembly are fixedly connected by two long screws 8.

[0047] This invention integrates a band switch, a push-button switch, and a signal light. Rotating the outer knob 3 of the combined handle drives the outer shaft 4, controlling the rotation of the band switch components and circuit switching. Pressing the inner button 1 of the combined handle drives the inner shaft 7 to press the lower push-button switch component, causing circuit switching. The wires leading from the LED light source 26 connect to circuit signals, controlling the light source to illuminate characters and provide feedback commands. Each component is structurally independent; the failure of any one component does not affect the normal operation of the other.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
