PURPOSE: A hazard switch system of a vehicle flickering at a collision is provided to give a signal to peripheral vehicles and to prevent an additional traffic accident by making an air bag expand and a hazard lamp operate at a vehicle collision. CONSTITUTION: A hazard switch system of a vehicle flickering at a collision includes a collision sensor(20) used for an air bag system; an ECU(Electronic Control Unit,30) for an air bag used to the air bag system; a hazard switch(40) operated by the ECU for the air bag; and a hazard lamp(41) operated by the hazard switch. A signal of the collision sensor is input to the ECU for the air bag. The collision sensor comprises a housing; an inertial mass part arranged to the inside of the housing; a lock combined to a slant surface or a groove of the inertial mass part according to the forward and backward movement of the inertial mass part; a spring elastically supporting the lock; a movable contact point formed to the front end of the inertial mass part; and a fixed contact point installed to the housing to be combined to the movable contact point when the groove of the inertial mass part and the lock are combined.
