[0002] As one of the most commonly used switches in a vehicle, the automotive glass lift switch has a high usage frequency. Therefore, particularly high requirements are imposed on its stability. Problems such as the looseness of the button, the improper pressing of the conductive rubber sheet, and water ingress may all cause the lift switch to malfunction. Moreover, in order to save costs, the switch is required to be miniaturized. Based on the above requirements, a single-window automotive switch structure with a compact structure and high stability is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an automotive window control switch that can achieve miniaturization while ensuring the stability of the switch.

The conductive rubber sheet is provided with an upward-lifting conductive rubber column and a downward-pressing conductive rubber column. A first ejector pin acting on the upward-lifting conductive rubber column and a second ejector pin acting on the downward-pressing conductive rubber column are disposed in the housing. The first ejector pin and the second ejector pin are arranged side by side and are both in a sheet structure. A first pressing block acting on the upward-lifting conductive rubber column is disposed at the bottom of the first ejector pin, and a second pressing block acting on the downward-pressing conductive rubber column is disposed at the bottom of the second ejector pin. A first pressing rib acting on the first ejector pin and a second pressing rib acting on the second ejector pin are disposed in the button. The first pressing rib and the second pressing rib are arranged in a staggered manner.

[0005] To prevent the first ejector pin and the second ejector pin from shifting or skewing, two ejector pin limiting plates are disposed in the housing. The first ejector pin and the second ejector pin are respectively placed in the inner cavities formed by the ejector pin limiting plates and the housing.

[0006] To prevent water from entering the interior of the switch, an upwardly protruding button mounting frame is provided on the upper surface of the housing. A pin shaft is disposed on the inner wall of the mounting frame, and a mounting hole adapted to the pin shaft is disposed on the inner wall of the button; a drainage groove is provided on one side of the mounting frame.

[0007] To further improve the reliability of circuit contact conduction, two upward-lifting conductive rubber columns are arranged side by side, and two downward-pressing conductive rubber columns are also arranged side by side. Grooves are provided at the tops of the upward-lifting conductive rubber columns and the downward-pressing conductive rubber columns, and protrusions adapted to the grooves are disposed at the bottoms of the first pressing block and the second pressing block.

[0008] To improve the waterproof performance of the circuit board, a limit frame adapted to the circuit board is provided inside the base, and circuit board limit posts are provided inside the limit frame. Notches adapted to the circuit board limit posts are provided on the circuit board. The width of the conductive rubber sheet is adapted to the limit frame. The conductive rubber sheet is pressed on the upper edge of the limit frame and is tightly sealed by clamping the conductive rubber sheet through the housing and the base.

[0009] Advantages of the present utility model: The present utility model realizes the conduction of the circuit through the cooperation of the first top post, the second top post, the upward pressing conductive rubber post and the downward pressing conductive rubber post. This structure occupies a small space and has good structural stability. The mounting frame and the drainage groove on the housing can prevent water from entering the switch, thereby improving the waterproof performance of the switch and avoiding failure due to internal water ingress. At the same time, the mounting and fixing structure of the limit frame and the conductive rubber sheet can further improve the waterproof performance of the circuit board, thereby improving the stability of the switch. The top post limiting plate on the housing can ensure that the top post will not be skewed during long-term use, thereby ensuring the reliability of the pressing conduction. The first rib and the second rib in the button are arranged in a staggered manner, which can improve the uniformity of the force on the button and can also improve the strength of the button, thereby ensuring the service life of the button.
