AI Technical Summary
Existing automotive button structures suffer from high costs due to the accumulation of tolerances in multiple components, making it difficult to control gaps, and ordinary rocker buttons have limited functionality.
It adopts a faceplate button switch structure, including a faceplate and a housing. The faceplate is installed through a rib groove and a snap-fit structure. It has an internal top post and a positioning post that cooperate with an elastic reset ball to achieve one-sided fixation and the other side tilting, reducing the number of parts and adopting a one-piece molding design.
It simplifies the number of parts, reduces costs, enables multi-directional tilting, improves quality control efficiency, and facilitates its adoption in different vehicle models.

Abstract
Claims
1. A faceplate push-button switch structure, comprising a faceplate (101) and a housing (104), wherein a PCB board assembly (107) is fixedly mounted inside the housing (104) and a plurality of push rods (105) are slidably mounted thereon, characterized in that, The faceplate (101) is mounted on the housing (104). One end of the faceplate (101) is a free pressing end. Each side of the free pressing end has a separate top post (101a), and the top post (101a) is located inside the faceplate (101). Each side of the free pressing end is laser-engraved with a character part (101y), and the character part (101y) is located outside the faceplate (101). After applying external pressure to the side of the free pressing end, the top post (101a) can contact the top rod (105), thereby enabling the micro switch (107a) of the PCB board assembly to be turned on. The faceplate (101) has an opening (101x) in the middle to accommodate the roller assembly (102).
2. The structure of the surface cover button switch according to claim 1, characterized in that, Each side of the other end of the face cover (101) has a separate positioning post (101b), and the positioning post (101b) is located inside the face cover (101).
