The spring 4 is always in a compressed state, when the button 1 and the toggle piece 2 toggle the swing rod 5 to any side, the extending direction of the spring 4 and the swing rod 5 form a certain included angle (less than 180 degrees), at the moment, the spring 4 can generate a certain radial bending or has a trend of generating the radial bending, and then the force for respectively continuing rotating is applied to the swing rod 5 and the rocker 3. Under this force, on the one hand, the movable contact 51 presses against the stationary contact 71; on the other hand, rocker 3 continues to produce the rotation for stirring 21, leans on until rocker 3 and installation cavity 21's inner wall, if stir 2 and button 1 and do not rotate extreme position this moment, then rocker 3 promotes to stir 2 and drives button 1 and continue to rotate extreme position, and then solves the problem that the button has virtual position.

In fig. 3 as an example, the "extreme position" means: the push button 1 and the toggle member 2 are rotated to positions at the maximum angle from the vertical direction, that is, the push button 1 and the toggle member 2 can be rotated to the leftmost and rightmost positions.

For example, the state shown in fig. 3 is an initial state of the rocker switch, if the left end of the button 1 is pressed at this time, the button 1 drives the toggle member 2 to rotate, the toggle member 2 drives the rocker 5 to synchronously rotate, and the rocker 5 toggles the spring 4 and the rocker 3 to rotate in the rotating process; until the movable contact 51 is attached to the left fixed contact 71, and the right end of the wane 3 is attached to the top wall of the installation cavity; at this moment, the button 1 is released, if the button 1 still does not rotate to the limit position, the spring 4 drives the rocker 3 to continue rotating, the right end of the rocker 3 abuts against the upper side wall of the mounting cavity 21 and pushes the toggle piece 2 to drive the button 1 to rotate to the limit position together, and therefore the problem of button virtual position is solved.

In some embodiments, referring to fig. 5, the side wall of the mounting cavity 21 adjacent to the push button 1 (the upper side wall of the mounting cavity 21 in fig. 5) is a first side wall 22: referring to fig. 3 and 6, the seesaw 3 includes: a rocker body 3 a; a rotating projection 3b, the rotating projection 3b being located on a side of the rocker body 3a close to the first side wall 22; the rotating protrusion 3b is rotatably connected to the first sidewall 22, and both ends (both ends of the rocker body 3a) of the rocker body 3a away from the rotating protrusion (3b) can abut against or be separated from the first sidewall 22. In this embodiment, the rocker body 3a is rotatably connected to the top wall (the first side wall 22) of the mounting cavity 21, the rocker 3 has a simple structure, and the rocker 3 and the toggle member 2 are convenient to assemble.

It should be noted that, in other embodiments, rotating shafts may be further disposed on two opposite sides of the rocker body 3a (for example, front and rear sides of the rocker body 3a in fig. 6), mounting holes matched with the rotating shafts are opened on two front and rear side walls of the mounting cavity 21, and the rotating connection between the rocker 3 and the toggle member 2 is realized through the cooperation of the rotating shafts and the mounting holes, but the structure of the rocker 3 is relatively complex in this manner, and the assembly difficulty of the rocker 3 and the toggle member 2 is high.

In some embodiments, referring to fig. 3, 5 and 6, the first sidewall 22 is provided with a rotation groove 221, a surface (upper surface) of the rotation protrusion 3b adjacent to the first sidewall 22 is arc-shaped, the rotation protrusion 3b is rotatably installed in the rotation groove 221, and the height of the rotation protrusion 3b is greater than the depth of the rotation groove 221. The pivoting groove 221 is used to restrict the rocker 3 from sliding relative to the toggle member 2 (in fig. 3, the rocker 3 is restricted from sliding in the horizontal direction). The height of the rotating protrusion 3b is greater than the depth of the rotating groove 221, so that a certain gap is formed between the rocker body 3a and the first sidewall 22, and the rocker 3 can rotate relative to the toggle member 2. If the height of the rotation protrusion 3b is smaller than or equal to the depth of the rotation groove 221, the surface of the rocker body 3a close to the first side wall will abut against the first side wall 22, and the rocker 3 cannot rotate relative to the toggle member 2.

Note that the "height of the rotating projection 3 b" means: the dimension of the rotating projection 3b in the direction perpendicular to the rocker body 3a, i.e., the dimension of the rotating projection 3b in the vertical direction in fig. 6; the "depth of the rotation groove 221" means: the dimension of the rotation groove 221 in the direction perpendicular to the first side wall 22, i.e., the dimension of the rotation groove 221 in the vertical direction in fig. 5.

Compared with the rotating groove 221 directly formed on the first sidewall 22 and recessed in the surface of the first sidewall 22, in the present embodiment, when the distance between the rocker body 3a and the first sidewall 22 is equal, the height of the rotating protrusion 3b can be reduced, the probability of deformation or fracture of the rotating protrusion 3b can be reduced, and the reliability of the rocker 3 can be improved. Wherein, the "distance between the rocker body 3a and the first sidewall 22" means: when the rocker body 3a is parallel to the first side wall 22, the distance between the two is large.

In some embodiments, referring to fig. 3 and 6, rocker 3 further comprises two abutment projections 3 c; the two abutting projections 3c are located at both ends of the rocker body 3a, respectively, and the abutting projections 3c are located on the side of the rocker body 3a close to the first side wall 22. The abutting protrusion 3c is used for abutting against the first side wall 22, and compared with the situation that the rocker body 3a is directly abutted against the first side wall 22, on one hand, the arrangement of the abutting protrusion 3c can reduce the swing amplitude of the rocker 3, so that the structure of the swing rod switch is more compact, and the occupied space of the swing rod switch is reduced; on the other hand, the abutment protrusion 3c may also prevent the rocker body 3a from directly colliding with the first sidewall 22, reducing wear of the rocker body 3 a.

In some embodiments, the surface of the abutment projection 3c adjacent to the first side wall 22 is arc-shaped, i.e. the surface of the abutment projection 3c against the first side wall 22 is arc-shaped. Even if the rocker 3 is worn or there is a machining error, the abutment projection 3c can be well abutted against the first side wall 22.

In some embodiments, the first side wall 22 is provided with a support rib 223 fitted with the abutment projection 3 c; in the process of pivoting the rocker 3, the abutment projection 3c abuts against the support rib 223. When the swing rod switch is shifted, the abutting protrusions 3c impact the first side wall 22, the supporting ribs 223 can strengthen the structural strength of the first side wall 22, the risk that the abutting protrusions 3c cannot abut against the first side wall 22 due to the fact that the pits appear on the first side wall 22 is reduced, and the reliability of the swing rod switch is improved.

In some embodiments, referring to fig. 3 and 6, the rocker 3 further comprises a docking post 3d, the docking post 3d is located on a side of the rocker body 3a away from the first side wall 22, and the docking post 3d is docked within the spring 4.
