The present invention relates to a contactless backup switch for a vehicle, opening and closing a backup lamp turned on to allow another person to recognize the backward movement of a vehicle when the vehicle is moving backward. The contactless backup switch for a vehicle comprises a body, a shaft, a diaphragm, a rod and a base. The body has a cylinder-shape and includes a shaft hole formed in the center thereof and a step pulley. The shaft is inserted into the shaft hole and has a shaft bracket positioned on a lower part thereof. The diaphragm is in close contact with a lower end of the shaft to be fixed. The rod is coupled to a lower part of the diaphragm, has a magnet positioned on a side surface thereof, and has a rod spring coupled to a lower part thereof. The base includes a main printed circuit board (PCB) and a magnetic sensing element, which are positioned inside, to be coupled to the body. A fault of a contact point due to impact caused when a backup lamp is opened and closed, fatigue accumulation or the like can be blocked, and a service period and durability of the backup switch can be remarkably improved. Moreover, the introduction of foreign substances into the backup switch is prevented. Furthermore, control speed is remarkably increased and operational feeling when performing switching can be noticeably reduced in comparison with a contact type-switch.

    본 발명은 차량의 후진 시 타인이 이를 인식할 수 있도록 점등되는 백업 램프를 개폐시키는 차량용 백업스위치에 관한 것으로 중앙에 샤프트 홀과 단차를 구비한 실린더 형상의 바디와 상기의 샤프트 홀에 삽입되며 하부에 샤프트 브라켓이 구비되는 샤프트와 상기의 샤프트 하단에 밀착 고정되는 다이어프램과 상기의 다이어프램 하부에 결합하며 측면에 자석이 구비되고 하부에 로드 스프링이 결합하는 로드와 내부에 메인 PCB와 자력감지소자가 구비되어 상기의 바디와 결합하는 베이스로 구성되는 차량용 무접점 백업스위치로서 백업 램프 개폐 시 충격이나 피로누적 등에 의한 접점 불량을 차단하고 백업스위치의 수명 및 내구성을 현저하게 향상시키는 효과가 있다. 또한, 백업스위치 내부로 유입되는 이물질을 차단하는 것은 물론, 제어 속도가 현저하게 빨라지며, 스위칭 시 접촉식 스위치와 대비하여 작동감을 현저하게 줄일 수 있는 효과가 있다.
