The invention discloses a motor vehicle backup lamp switch with high durability, and belongs to the field of automobile switch devices. The switch comprises a shell, a lug plate is mounted on the upper end face of the shell, a wire inlet seat and a wire outlet seat are electrically connected to the lower end of the lug plate, contact pieces are arranged below the wire inlet seat and the wire outlet seat, and a pushing part is mounted in the shell. A contact blade is installed below the pushing part, and the lower end of the contact blade is fixedly connected with a contact. According to the invention, the wiring sheet and the contact sheet adopt riveted silver contacts, so that the problem of conductive ablation carbon deposition is fully solved. By adopting a split structure, foreign matters in a reversing lamp switch shell and an automobile transmission are effectively prevented from entering to cause the reversing switch to be normally turned on or not turned on to fail, and transmission oil contamination is prevented from polluting a contact to accelerate carbonization and seriously affect the service life of the reversing lamp switch and personal safety; and the connecting part and the pushing part are separately machined and assembled, so that the manufacturing difficulty of parts can be reduced, the yield can be improved, and the manufacturing cost is reduced.
本发明公开了一种耐久性高的机动车倒车灯开关,属于汽车开关装置领域,包括壳体,壳体的上端面安装有接线片,接线片的下端电性连接有进线座和出线座,进线座和出线座的下方设置有接触片,壳体的内部安装有推动部分,推动部分的下方安装有触头片,触头片的下端固定连接有触头,本发明将接线片和接触片采用铆接银触点,充分解决导电烧蚀积炭问题;采用分体式结构,有效避免倒车灯开关壳体与汽车变速器里的异物进入从而引起倒车开关出现常亮和不亮而失效、变速器油污对触点的污染从而加速碳化和严重影响倒车灯开关使用寿命和人身安全;将接通部分与推动部分采用分体加工组装,能够降低零件制造难度,有利于提高产量,降低制造成本。
