A structure of a horn switch is provided to minimize friction between a movable terminal and a driving terminal by forming an uneven groove on a surface of a contact point plate. A screw groove(3) is formed on a top of a hub core(1). A horn plate(11) has a movable terminal(12), and is fixed in a top part of a bolt(31) inserted in the screw groove. An insulator(14) is fixed in a coupling part of the horn plate and the bolt. An elastic spring(32) is installed in a bottom of the insulator, and maintains an optimal interval between the horn plate and the hub core. A contact point plate(21) supports a bottom of the elastic spring. A fixing terminal(22) corresponding to the movable terminal is formed in one end of the contact point plate. The contact point plate is adhered to a top surface of the hub core.
