the outer side surface of the stress part 22 is a spherical curved surface; a swing cavity 111 is arranged at the bottom of the swing rod 11, and the force-bearing part 22 rotates in the swing cavity 111;

the elastic piece 12 pushes the marble 13 to abut against the pressure head 2, and the pressure head 2 is suitable for driving the contact piece component 3 to switch between a closed state and an open state when the swing rod 11 swings.

The utility model discloses a moving plate that multiple spot position supported supports tight structure and is applied to panel switch, moving plate that multiple spot position supported supports tight structure and sets up in panel switch's casing 4, elastic component 12, pellet shot from a slingshot 13 and pressure head 2 compress tightly each part of contact subassembly 3, user's accessible presses panel 5 of panel switch, make panel 5 take place the pivot, by the swing of panel 5 drive pendulum rod 11, pendulum rod 11 stirs the swing of pressure head 2 at the wobbling in-process, and then realize making contact subassembly 3 switch between closed state and off-state. The direction of the force transmitted to the swing assembly 1 and the elastic element 12 by the panel 5 in the process of pivoting is along the axial direction of the swing rod 11, because the traditional moving plate abutting structure is that the bottom of the elastic element 12 directly abuts against the swing assembly, and the swing rod 11 drives the contact plate assembly 3 to act, because the contact area between the elastic element 12 and the contact plate assembly is extremely small and only two points contact, in the process that the swing rod 11 drives the contact plate assembly 3 through swinging, the spring can be distorted and cannot compress the swing assembly, and when the swinging angle of the swing rod 11 is small, the spring can easily generate the force opposite to the action direction of the swing assembly 1, so that the product is extremely unstable in the use process.

The utility model is provided with the pressure head 2 and the marble 13, as an optional implementation mode, the marble 13 can be in a quadrangular structure, a cylindrical structure or other polygonal structures, wherein the elastic element 12 is connected with the marble 13, the contact piece component 3 is connected with the pressure head 2, the pressure head 2 is connected with the marble 13 through the groove 131 and the force-bearing part 22 in a rotating fit way, because the groove 131 is of a V-shaped structure, the groove 131 is in multi-point contact with the force-receiving portion 22, when the swing rod swings to different directions, the pressure of the two surfaces of the groove 131 to the force receiving portion 22 is the same, because the swing rod forms a certain included angle with the horizontal plane when swinging to two extreme positions, the groove 131 applies a pressure with a certain angle with the vertical direction to the force-bearing part 22 through the groove 131, so that the force-bearing part 22 can be pressed, and the included angle formed by the force-bearing part 22 and the horizontal plane can be maintained. And because the groove 131 is in multi-point contact with the force-receiving portion 22, the process of pressing the pressure head 2 by the marble 13 is more stable. As one embodiment, the elastic member 12 is a spring, and the guide rod 131 can limit the bottom of the elastic member 12, so that the elastic member 12 always abuts against the top of the marble 13, and the elastic member 12 is not easily twisted during the swinging process of the swing rod 11.
