[0027] 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 onto the front and sides of the base 1, while intermediate terminals 5 are riveted onto the rear and sides of the base 1. Stationary contacts 6 are riveted onto the inner sides of the normally open and normally closed terminals 3 and 4. A C-shaped bracket 7 is integrally formed at the upper end of the intermediate terminal 5, and a movable contact 9 is fixed to the C-shaped bracket 7 via V-shaped grooves 8 at both ends. The movable contact 9 comprises a square frame 10, a reset spring 11 integrally formed at the front end of the square frame 10, and a movable contact 12 riveted to the front end of the square frame 10. The movable contact 12 is normally closed to the stationary contact 6 on the normally closed terminal 4 via the reset spring 11. A swinging operating member 13 is provided in the middle of the base 1. The swinging operating member 13 comprises a rotating shaft 14, a first operating lever 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, with both ends of the U-shaped push plate 17 abutting against the square frame 10. When the first operating lever 15 swings left and right, the swing arm 16 drives the U-shaped push plate 17 to slide left and right, causing the U-shaped push plate 17 to apply pressure to the movable contact piece 9, thereby causing the movable contact 12 to contact the static contact 6 on the normally open terminal 3, thereby switching the circuit.

[0028] Preferably, a positioning plate 18 is integrally formed on one side of the swing arm 16, and a positioning slot 19 is provided at the bottom of the base 1 for positioning the positioning plate 18. The cooperation between the positioning plate 18 and the positioning slot 19 limits the maximum swing stroke of the swing arm 16 to prevent deformation of the movable contact piece 9 caused by excessive swinging.

[0029] 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.

[0030] Preferably, a mounting bracket 21 is integrally formed on the base 1. The mounting bracket 21 includes a shaft mounting seat 22 connected to the shaft 14, a slot 23 engaged with the front end of the C-shaped bracket 7, and a first slide groove 24 slidably engaged 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 bracket 21 allows the shaft 14, the C-shaped bracket 7, and the U-shaped push plate 17 to be installed and positioned, thereby improving overall stability.

[0031] Preferably, the upper cover 2 is provided with a carbon cleaning mechanism 27, comprising a pressing rod 28 slidably disposed on the upper cover 2, a return spring 29 mounted on the pressing rod 28, and a flat brush head 30 disposed at the lower end of the pressing rod 28. The brush head 30 has a frosted layer 31 on its surface and is positioned between the stationary contact 6 and the movable contact 12. The lower end of the return spring 29 abuts against the upper cover 2, and the lower end abuts against a button 54 at the upper end of the pressing rod 28. To remove carbon deposits, the pressing rod 28 is continuously pressed, causing the brush head 30 to rub against the surfaces of the stationary contact 6 and the movable contact 12, effectively removing the carbon deposits through the frosted layer 31.

[0032] 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. Example 2:

[0033] like Figures 9 to 12As shown, the automobile seat adjustment switch assembly of the present invention includes a housing 32, a PCB board 33 disposed within the housing 32, a movement and elevation adjustment switch 34, a backrest adjustment switch 35, and a lumbar support adjustment switch 36 disposed on the PCB board 33, and a panel 37 covering the housing 32. The movement and elevation adjustment switch 34 includes the two-way adjustment switch a described in any one of the first embodiments and a four-way adjustment switch 38 disposed adjacent to the two-way adjustment switch a. The four-way adjustment switch 38 can be swung left and right, up and down, via its second operating lever 39. The four-way adjustment switch 38 is well known in the art and will not be described in detail here. A linked operating button assembly is provided on the end surface of the housing 32, connected to the first operating lever 15 of the two-way adjustment switch a and the second operating lever 39 of the four-way adjustment switch 38. The linked operating button assembly includes a push cap 41 and a linkage frame 42 disposed at the bottom of the push cap 41. The linkage frame 42 includes a sliding plate 43 slidably mounted to the bottom of the panel 37 and a vertical plate 44 integrally formed in the middle of the sliding plate 43. A first operating rod connecting sleeve 45 and a second operating rod connecting sleeve 46 are respectively provided on either side of the vertical plate 44. The first operating rod connecting sleeve 45 has an elongated slot 47 at its bottom, while the second operating rod connecting sleeve 46 has a circular slot 48 at its bottom. A positioning cover 50 is provided at the bottom of the panel 37, covering the sliding plate 43. The top of the first operating rod 15 is slidably mounted within the elongated slot 47. The top of the second operating rod 39 is mounted within the circular slot 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 slot 47, the left and right pushing of the push cap 41 will not affect the two-way adjustment switch a.

[0034] 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. This makes the connection between the linkage frame 42 and the first operating rod 15 and the second operating rod 39 more stable, and the swinging is also more stable.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
