The present invention relates to a button start-up switch for a vehicle with an improved installation structure of an antenna coil to improve an immobilizer function. The button start-up switch according to the present invention comprises: a housing which is provided with an installation groove therein; a circuit unit which includes a switch and is installed in the installation groove of the housing; a movable member which is installed to be movable in the housing to operate the switch of the circuit unit; a switch button which is connected to the movable member and is installed to be exposed out of the housing; a bobbin which is installed in the installation groove of the housing; and an antenna coil which is supported on the bobbin to be electrically connected to the circuit unit, and is wound at the center of the bobbin along the circumference of the bobbin to be separated from both ends of the bobbin at predetermined intervals. In the button start-up switch for a vehicle according to the present invention, the antenna coil is wound on the bobbin to be separated from both ends of the bobbin at predetermined intervals, it is possible to make the magnetic flux line distribution denser at the center of the bobbin, and it is possible to further expand a magnetic field signal of the antenna coil. |
