PURPOSE: A multi-functional switch assembly of a vehicle is provided to detect precise steering wheel-angular velocity with a steering wheel-angular velocity sensor unit. CONSTITUTION: In a multi-functional switch assembly of a vehicle, a cancel cam(12) forming plural slit holes(12a), a return spring(17) separably combined to the upper part of the cancel cam, and a steering wheel-angular velocity sensor unit(16) detecting the rotational direction, rotational angle, and rotational speed of the slit hole and detecting the steering angle of a steering wheel are integrally assembled in a case composed of a lower case(21) and an upper cover(23) and combined to a securing portion of a body plate by plural screws. Thus, the cancel cam and the steering wheel-angular velocity sensor unit are prevented from being exposed to the room, and dust and foreign material are prevented from coming into the slit holes. Accordingly, the steering wheel-angular velocity sensor unit can detect a precise steering angle.
