Patent ID: 7671288

Claim:
A switch apparatus for horn device of a vehicle, comprising: an inflator housing installed in a steering wheel of the vehicle, and configured to accommodate an airbag inflator, wherein the inflator housing and the airbag inflator are insulated therebetween; a terminal unit provided in the inflator housing, and configured to include a first contact element electrically connected to the inflator accommodated in the inflator housing and a second contact element electrically connected to the inflator housing; a switching plate electrically connected to the horn device and installed to be spaced apart from the inflator housing, the switching plate being biased from the inflator housing by using insulated elastic member so that the switching plate makes electrical contact with the inflator housing in case that external pressure applied to the inflator housing is sufficiently enough to surmount an elastic force of the insulated elastic member, thereby operating the horn device; and a connector unit coupled to the terminal unit, the connector unit having inflator wires and a horn wire inserted into one end of the connector unit and provided therein with a first connection element for connecting the inflator wires to the first contact element of the terminal unit and a second connection element for connecting the horn wire to the second contact element of the terminal unit so that the horn wire and the inflator housing are electrically connected each other.
