The present invention provides a seat belt contactless switch for a vehicle, which outputs an airbag control signal, tension, and operation signal depending on whether the seat belt is worn or not by operating a power supply self-holding circuit to supply or cut off the constant power to a circuit part with the tongue fastening or disconnection trigger signal of a switch circuit part by a fastening power or disconnection power signal generated according to the flow direction of electromagnetic induced current generated by a cylindrical bar magnetic body reciprocating in an internal combustion space of an induction coil as the tongue attached to the seat belt attaches and detaches from a buckle.
본 발명은 안전벨트에 부착된 텅이 버클에 착, 탈함에 따라, 원통형 막대자성체가 유도코일부의 내연공간을 왕복함으로써 발생되는 전자기유도 전류의 흐름방향에 따라 발생한 체결전원 또는 탈거전원 신호에 의해, 스위치회로부의 텅 체결 또는 탈거트리거 신호로 회로부에 상시전원을 공급 또는 차단하기 위해 전원자기유지회로 동작시켜, 안전벨트 착용여부에 따라 에어백 제어신호와 텐션 및 동작신호를 출력하는 차량용 안전벨트 비접촉식 스위치를 제공한다.
