A switch apparatus for the horn device of a vehicle includes an inflator housing and a terminal unit provided in the inflator housing and configured to include a first contact element connected to the inflator and a second contact element connected to the inflator housing. A switching plate is installed using elastic members, which are spaced apart and insulated from the inflator housing, so that the switching plate makes contact with the inflator housing if the inflator housing is pressed, thereby operating the horn. A connector unit is coupled to the terminal unit with inflator wires and a horn wire, and is provided therein with a first connection element and a second connection element so that the horn wire and the inflator housing are electrically connected to each other.

What is claimed is: 1. 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. 2. The switch apparatus as set forth in claim 1, wherein the terminal unit has a depression into which the connector unit is inserted, the first contact element of the terminal unit includes pins provided inside the terminal unit, and the first connection element of the connector unit includes clips embedded in the connector unit so that the first contact element is inserted thereto. 3. The switch apparatus as set forth in claim 1, wherein the terminal unit has a depression into which the connector unit is inserted, the first contact element of the terminal unit includes clips provided inside the terminal unit, and the first connection element of the connector unit includes pins embedded in the connector unit so that the second contact element is inserted thereto. 4. The switch apparatus as set forth in claim 1, wherein the terminal unit has a depression into which the connector unit is inserted, the second contact element of the terminal unit includes conductor panels electrically connected to the inflator housing, and the second connection element of the connector unit includes a clip configured to be connected on a first side thereof to the horn wire and to be extended along an outside of the first contact element to contact the conductor panels of the second contact element. 5. The switch apparatus as set forth in claim 4, wherein the second contact element is provided on both sides of the terminal unit, and the second connection element is provided on a second side thereof with opposite protrusions that come into contact with the second contact element. 6. The switch apparatus as set forth in claim 5, wherein the opposite protrusions are inclined downwards with a predetermined angle. 7. The switch apparatus as set forth in claim 6, wherein the opposite protrusions and the first contact element are aligned in a common axis when the connector unit and the terminal unit are coupled. 8. The switch apparatus as set forth in claim 1, wherein a housing plate is installed on the inflator housing and electrically connected therebetween, and the switching plate is electrically connected to the horn device and installed to be spaced apart from the housing plate, the switching plate being biased from the housing plate by using insulated elastic member so that the switching plate makes electrical contact with the housing plate in case that external pressure applied to the housing plate is sufficiently enough to surmount an elastic force of the insulated elastic member, thereby operating the horn device. 9. The switch apparatus as set forth in claim 8, wherein a central opening is formed in the housing plate, the terminal unit is provided in the inflator housing exposed through the central opening, and the switching plate is configured to correspond to and face the housing plate so that the switching plate does not interfere with the inflator wires and the horn wire. 10. The switch apparatus as set forth in claim 1, wherein the inflator wires and the horn wire are integrally formed. 11. The switch apparatus as set forth in claim 1, wherein the inflator wires and the horn wire are accommodated in a single cable and then inserted into the one end of the connector unit. 12. A passenger vehicle comprising the switch apparatus as set forth in claim 1. 13. A connector unit for horn device of a vehicle, comprising: a casing; inflator wires and a horn wire inserted into a first end of the casing; a first connection element and a second connection element respectively connected to the inflator wires and the horn wire; and wherein a second end of the casing is inserted into a inflator housing and the first connection element is connected to a airbag inflator accommodated in the inflator housing and a second connection element is extended to an outside of the casing so that the horn wire and the inflator housing electrically connected each other. 14. The connector unit as set forth in claim 13, wherein the first connection element of the connector unit includes clips embedded in the casing and the second connection element of the connector unit includes a clip configured to be connected on a first side thereof to the horn wire and to be extended along an outside of the casing. 15. The connector unit as set forth in claim 14, wherein the second connection element is provided on a second side thereof with opposite protrusions that come into contact with the inflator housing. 16. The connector unit as set forth in claim 15, wherein the opposite protrusions are inclined downwards with a predetermined angle. 17. The connector unit as set forth in claim 13, wherein the inflator wires and the horn wire are integrally formed. 18. The connector unit as set forth in claim 13, wherein the inflator wires and the horn wire are accommodated in a single cable and then inserted into the first end of the casing.
