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 for a vehicle 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 coil winding member which has a width smaller than the width of the switch button on the outside of the edge of the switch button; and an antenna coil which is wound on the coil winding member along the circumference thereof to be electrically connected to the circuit unit. In the button start-up switch for a vehicle according to the present invention, the antenna coil is not wound on the circumference of the switch button like an existing method, and is disposed in a form of being wound at a position separated from the edge of the switch button, and thus the antenna coil is less affected by electromagnetic shielding based on a thin metal film of the switch button. |
