DETAILED DESCRIPTION Embodiment 1:

[0016] like Figures 1 to 8As shown, the two-way regulating switch of the present invention comprises a base 1 and an upper cover 2. Normally open terminals 3 and normally closed terminals 4 are riveted on both sides of the front end of the base 1, and intermediate terminals 5 are riveted on both sides of the rear end of the base 1. Static contacts 6 are riveted on the inner sides of the normally open terminals 3 and the normally closed terminals 4. A C-shaped bracket 7 is integrally formed on the upper end of the intermediate terminal 5, and a moving contact piece 9 is fixed to the C-shaped bracket 7 through V-shaped grooves 8 at both ends. The moving contact piece 9 comprises a square frame 10, a reset spring piece 11 integrally formed at the front end of the square frame 10, and a moving contact 12 riveted on the front end of the square frame 10. The moving contact 12 is normally closed with the static contact 6 on the normally closed terminal 4 through the reset spring piece 11. A swing operating member 13 is provided in the middle of the base 1, and the swing operating member 13 comprises a rotating shaft 14, a first operating rod 15 integrally formed at the upper end of the rotating shaft 14, and a swing arm 16 integrally formed at the lower end of the rotating shaft 14. A U-shaped push plate 17 is provided at the bottom of the swing arm 16, and both ends of the U-shaped push plate 17 are against the square frame 10. When the first operating rod 15 swings left and right, the swing arm 16 drives the U-shaped push plate 17 to slide left and right, so that the U-shaped push plate 17 applies pressure to the moving contact piece 9, so that the moving contact 12 contacts the static contact 6 on the normally open terminal 3, thereby realizing the switching of the circuit.

[0017] Preferably, a positioning plate 18 is integrally formed on one side of the swing arm 16, and a positioning groove 19 is provided at the bottom of the base 1 for positioning the positioning plate 18. Through the cooperation between the positioning plate 18 and the positioning groove 19, the maximum swing stroke of the swing arm 16 is limited to prevent deformation of the movable contact piece 9 caused by excessive swinging.

[0018] Preferably, the rear end of the square frame 10 of the movable contact piece 9 is integrally formed with a buckle 20 that is clamped to the C-shaped bracket 7 to prevent the square frame 10 from falling off.

[0019] Preferably, a mounting frame 21 is integrally formed on the base 1, and the mounting frame 21 includes a shaft mounting seat 22 connected to the shaft 14, a slot 23 clamped to the front end of the C-shaped bracket 7, and a first slide groove 24 slidably matched with the U-shaped push plate 17. The shaft mounting seat 22 is provided with an inclined guide surface 25 and an axis hole 26. The mounting frame 21 can realize the installation and positioning of the shaft 14, the C-shaped bracket 7 and the U-shaped push plate 17 to improve the overall stability.

[0020] Preferably, the upper cover 2 is provided with a carbon cleaning mechanism 27, and the carbon cleaning mechanism 27 includes a pressing rod 28 slidably arranged on the upper cover 2, a reset spring 29 arranged on the pressing rod 28, a flat brush head 30 is arranged at the lower end of the pressing rod 28, and a frosted layer 31 is arranged on the surface of the brush head 30, and the brush head 30 is placed between the static contact 6 and the moving contact 12. The lower end of the reset spring 29 abuts against the upper cover 2, and the lower end abuts against the button 54 at the upper end of the pressing rod 28. When the carbon deposits are to be removed, the brush head 30 is rubbed against the surfaces of the static contact 6 and the moving contact 12 by continuously pressing the pressing rod 28, and the carbon deposits can be effectively removed through the frosted layer 31.

[0021] Preferably, the brush head 30 is a stainless steel sheet, and the frosted layer 31 is formed by embossing, so that the brush head 30 has the advantages of being durable and the frosted layer is not easy to fall off. Embodiment 2:

[0022] like Figures 9 to 12As shown, the automobile seat adjustment switch assembly of the present invention comprises a housing 32, a PCB board 33 arranged in the housing 32, a movement and lifting adjustment switch 34, a backrest adjustment switch 35, a lumbar support adjustment switch 36 arranged on the PCB board 33, and a panel 37 covering the housing 32. The movement and lifting adjustment switch 34 comprises the two-way adjustment switch a described in any one of the embodiments 1 and a four-way adjustment switch 38 arranged beside the two-way adjustment switch a. The four-way adjustment switch 38 can be swung left and right and up and down through its second operating rod 39. The four-way adjustment switch 38 is a well-known technology and is not described here. The end surface of the housing 32 is provided with a linkage operation button device connected to the first operating rod 15 of the two-way adjustment switch a and the second operating rod 39 of the four-way adjustment switch 38. The linkage operation button device comprises a push cap 41 and a linkage frame 42 arranged at the bottom of the push cap 41, and the linkage frame 42 comprises a sliding plate 43 slidably mounted at the bottom of the panel 37 and a vertical plate 44 integrally formed in the middle of the sliding plate 43. The first operating rod connecting sleeve 45 and the second operating rod connecting sleeve 46 are respectively provided on both sides of the vertical plate 44. The bottom of the first operating rod connecting sleeve 45 is provided with a long groove 47, and the bottom of the second operating rod connecting sleeve 46 is provided with a circular groove 48. The bottom of the panel 37 is provided with a positioning cover plate 50 covering the sliding plate 43. The top of the first operating rod 15 is slidably installed in the long groove 47. The top of the second operating rod 39 is installed in the circular groove 48. When the front end of the push cap 41 is swung up and down, the first operating rod 15 is driven to swing up and down through the linkage frame 42 to operate the two-way adjustment switch a; when the rear end of the push cap 41 is swung up and down, the second operating rod 39 is driven to swing up and down through the linkage frame 42 to operate the four-way adjustment switch 38; when the push cap 41 is pushed left and right, the second operating rod 39 is driven to swing left and right through the linkage frame 42 to operate the four-way adjustment switch 38, but since the top of the first operating rod 15 is slidably installed in the long groove 47, the left and right pushing of the push cap 41 will not affect the two-way adjustment switch a.

[0023] Preferably, the first operating rod 15 is provided with a longitudinal ball head 51 connected to the long groove 47, and the second operating rod 39 is provided with a transverse ball head 52 connected to the circular groove 48. Thus, the connection between the linkage frame 42 and the first operating rod 15 and the second operating rod 39 is more stable, and the swing is also more stable.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention are included in the protection scope of the present invention.
