[0035] The control mechanism includes a button 8 and a connecting rod 9. The button 8 is arranged in the mounting cover 2. One end of the connecting rod 9 abuts against the middle position of the rocker 5 and is used to control the swing of the two ends of the rocker 5. The other end of the connecting rod 9 is slidably arranged in the button 8.

[0036] In the present technical solution, the mounting cover 2 is installed and fixed on the base 1, a protrusion 81 is provided on the outer side of the button 8, and a recessed hole 21 adapted to be snap-fitted with the protrusion 81 is provided on the inner side of the mounting cover 2, and the button 8 is mounted on the mounting cover 2 through the snap-fit ​​connection between the protrusion 81 and the recessed hole 21.

[0037] A support frame is provided inside the base 1, and a seesaw 5 is provided on the support frame. Both ends of the seesaw 5 can swing up and down in the Z direction so that the probe assembly 6 on the seesaw 5 can contact the contact block 4 provided in the base 1, thereby connecting the circuit. A connecting rod 9 is provided through the mounting cover 2, and a spherical portion is provided on one end of the connecting rod 9 to abut against the seesaw 5. By pressing one end of the button 8, the spherical portion of the connecting rod 9 drives one end of the seesaw 5 to descend so that the probe assembly 6 contacts the contact block 4 to complete the circuit connection, thereby realizing the conduction of the circuit controlled by the button 8.

[0038] The probe assembly 6 is slidably connected to the seesaw 5, and a first spring 7 is arranged axially abutting between the probe assembly 6 and the seesaw 5. When the probe assembly 6 contacts the contact block 4, the first spring 7 is squeezed to generate elastic force to act on the probe assembly 6, so that the probe assembly 6 and the contact block 4 are kept in close contact, thereby improving the connection stability between the probe assembly 6 and the contact block 4. In addition, when the button 8 is squeezed by a large external force, the first spring 7 can also play a certain buffering role to avoid collision between the probe assembly 6 and the seesaw 5 and cause damage.

[0039] In summary, through this structural design, it is possible to effectively avoid the influence of poor contact between the probe assembly 6 and the contact block 4 on the conduction of the circuit, ensuring that the button 8 can respond quickly when in use, which is safer and more practical.

[0040] Embodiment 2:

[0041] This embodiment provides a switch for an automobile, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] Furthermore, the probe assembly 6 includes:

[0043] A guide rod 61, wherein the guide rod 61 passes through the seesaw 5 and is slidably connected to the seesaw 5;

[0044] A connecting probe 62, wherein the connecting probe 62 is arranged on one end of the guide rod 61 close to the contact block 4;

[0045] a stopper 63, the stopper 63 being disposed on the other end of the guide rod 61 and abutting against the seesaw 5;

[0046] The first spring 7 is axially abutted between the connecting probe 62 and the rocker 5 .

[0047] In the present technical solution, the connection probe 62 and the guide rod 61 are integrally connected, and a stopper 63 is provided on the other end of the guide rod 61. The stopper 63 can be a nut threadedly connected to the guide rod 61, or a spring clamped and fixed to the guide rod 61. When the connection probe 62 contacts the contact block 4, the first spring 7 is compressed, the guide rod 61 slides, and the elastic force generated by the first spring 7 pushes the connection probe 62 to keep close to the contact block 4, so that the connection between the connection probe 62 and the contact block 4 is stable and reliable. When the connection rod 9 controls the end of the seesaw 5 to move away from the contact block 4, the first spring 7 returns to its original state, pushing the connection probe 62 to drive the guide rod 61 to slide, so that the probe assembly 6 as a whole returns to its original state, and the stopper 63 plays a role in limiting the movement of the guide rod 61 to prevent the guide rod 61 from separating from the seesaw 5.

[0048] Furthermore, the first spring 7 is sleeved on the guide rod 61. This structural design can effectively enhance the expansion and contraction stability of the first spring 7, thereby making the contact connection between the connection probe 62 and the contact block 4 more stable and reliable, and improving practicality.
