    • A push-lock switch for an automotive vehicle is provided to solve problem generated in the separate control unit since locking is operated according to the current applied at the magnetism portion and in self-return is performed in unlocking. In a push-lock switch(100) for an automotive vehicle, a magnetism portion(210) installed inside of the locking body which is connected to the inner side of the switch and supplies a current with power on at the same time. A holder(220) ascends and descends through a penetration hole formed in the upper of locking body and ascends up the penetration hole in supplying to the magnetism portion and descends down the penetration hole in cutting off the current. A locking unit(200) includes the protrusion pin(230) of which one side is installed the upper of the locking body and the other end is extended to the holder while being installed at the upper side of the locking body. A cover housing(300) accommodated in the locking unit guides the smooth operation of the locking unit.
