An oil pressure switch for a vehicle is provided to prevent corrosion and abnormal operation of an oil pressure warning lamp by boring air passage holes through the inside of the switch. An oil pressure switch for a vehicle, includes a sealing ring(21), a film(22), an operating member(23), a fixed contact plate(24) and a movable contact plate(25), a spring(26), a terminal(27), and a lower body(30) which are sequentially arranged in an operating chamber(20). The operating member operates by the film. The fixed contact plate and the movable contact plate have lower portions equipped with the operating member. The spring provides elastic force to the movable contact plate. The terminal is connected to the spring. The lower body has a center with a terminal hole(28). The switch has an inside through which air passage holes(1) are formed to make the internal pressure of the operating chamber same with atmospheric pressure.
