The present invention relates to a door switch for a vehicle which confirms whether a door is opened or closed in a non-contact structure of detecting change in magnetic resistance. The door switch for a vehicle according to the present invention comprises: a conductive coil supporter which is installed at a vehicle body portion facing a door of a vehicle; an excitation coil and a detection coil which are individually wound on the coil supporter; and a detector which is electrically connected to the detection coil to detect voltage induced in the detection coil. The coil supporter includes a first coil winding portion which is disposed such that one end thereof is directed to the inner surface of the door, a second coil winding portion which is separated from the first coil winding portion and is disposed such that one end thereof is directed to the inner surface of the door, and a connection portion which connects the first coil winding portion to the second coil winding portion. The excitation coil is wound around the first coil winding portion of the coil supporter to generate magnetic flux flowing along the coil supporter by receiving power, and the detection coil is wound on the second coil winding portion of the coil supporter to induce voltage by magnetic flux flowing along the coil supporter.

    본 발명은 자기 저항 변화를 감지하는 비접촉식 구조로 도어의 개폐 여부를 확인할 수 있는 차량용 도어 스위치에 관한 것이다. 본 발명의 차량용 도어 스위치는, 차량의 도어와 마주하는 차체 부분에 설치되는 전도성의 코일 지지체와, 코일 지지체에 각각 권취되는 여자 코일 및 감지 코일과, 감지 코일에 유도되는 전압을 검출하기 위해 감지 코일과 전기적으로 연결되는 검출기를 포함한다. 코일 지지체는 한쪽 끝단이 도어의 내측면을 향하도록 배치되는 제 1 코일 권취부와, 제 1 코일 권취부와 이격되어 한쪽 끝단이 도어의 내측면을 향하도록 배치되는 제 2 코일 권취부와, 제 1 코일 권취부와 제 2 코일 권취부를 연결하는 연결부를 갖는다. 여자 코일은 전원을 공급받아 코일 지지체를 따라 흐르는 자속을 생성하도록 코일 지지체의 제 1 코일 권취부에 권취되고, 감지 코일은 코일 지지체를 따라 흐르는 자속에 의해 전압이 유도되도록 코일 지지체의 제 2 코일 권취부에 권취된다.
