Switch lever for vehicle

1. A switch lever for vehicle, comprising:

a hollow first lever arm connected to and rotatable by a first knob, the first lever arm having a first protrusion extended and tilted from an end of the first lever arm;

a second lever arm, coaxially aligned within the first lever arm, connected to and rotatable by a second knob, the second lever arm having a second protrusion extended and tilted from an end of the second lever arm;

a guide member having first and second guide grooves; a first contact terminal connected to the first protrusion and positioned in the first guide groove, wherein the first contact terminal is movable along the first guide groove when the first knob rotates;

a second contact terminal connected to the second protrusion and positioned in the second guide groove, wherein the second contact terminal is movable along the second guide groove when the second knob rotates; and

a single insulation part having a fixed terminal thereon, the fixed terminal being capable of contacting with at least one of the first and second contact terminals to generate an electric signal when said at least one of the first and second contact terminals moves.

2. A switch lever for a vehicle comprising:

a plurality of knobs that perform a rotation manipulation in order to turn on, or turn on or off a headlight or a fog light of a vehicle, or to adjust a wiping interval of a windshield wiper of the vehicle;

a pair of lever arms that are disposed within and rotate with the knobs according to a rotation of the knobs;

a pair of contact terminals each that is installed at an end part of one side of the lever arms to move according to a rotation of the lever arms;

a guide member having guide grooves, wherein each contact terminal is positioned in each guide groove and linearly moves along each guide groove: according to the rotation of the lever arms; and

a single insulation part having a fixed terminal disposed thereon, wherein the fixed terminal contacts with each of the contact terminals to generate an operation signal when each contact terminal linearly moves along each guide groove; wherein

the pair of lever arms comprise a hollow first lever arm and a second lever arm which is coaxially aligned within the first lever arm.

3. The switch lever for a vehicle of claim 2 , wherein the fixed terminal is formed at an upper part of the single insulation part.

4. The switch lever for a vehicle of claim 1 , wherein a hollow lever holder is installed within a lever body, and the pair of lever arms penetrate the inside of the lever holder, wherein the knobs are fixed to the lever body.

5. The switch lever for a vehicle of claim 4 , wherein a coupling part is bent along a tilt line for forming a predetermined angle relative to a length direction of the lever holder at the end part side of the lever holder adjacent to the protruding part of the lever arm.

6. The switch lever for a vehicle of claim 1 , wherein the pair of lever arms further comprises:

the first lever arm forms a cylindrical body extended to a predetermined length, in which a coupling part for coupling one knob is formed at an end part of one side of the first lever arm, and in which a protruding part for coupling one contact terminal is formed at an end part of the other side thereof; and

the second lever arm forms a cylindrical body extended to a predetermined length that can house by penetrating the first lever arm to the inside thereof and in which a coupling part for coupling another knob is formed at an end part of one side of the second lever arm, and in which a protruding part for coupling the remaining contact terminal is formed at an end part of the other side thereof.

7. The switch lever for a vehicle of claim 6 , wherein the protruding part is formed in a spherical shape or a hemispherical shape.

8. The switch lever for a vehicle of claim 6 , wherein the protruding part is bent along a tilt line for forming a predetermined angle relative to a length direction of the lever arm from one end of the each lever arm.

9. The switch lever for a vehicle of claim 6 , wherein a ring-shaped arm holder for preventing interference due to a contact between the first lever arm and the second lever arm is mounted at an end part of the protruding part side of the first lever arm.
