A switch lever for a vehicle comprising: - a lever body having a plurality of knobs (6, 8) that perform a rotation manipulation in order to 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 lever holder disposed within the lever body; - a pair of lever arms (14, 16) that are disposed within the lever holder to be rotated according to a rotation of the knobs (6, 8); - a pair of contact terminals (28, 30) each of which is installed at an end part of one side of the lever arms (14, 16) to move according to a rotation of the lever arms (14, 16); - a guide member in which each of guide grooves (26, 26') for arriving and moving the contact terminals (28, 30) is formed; and - an insulation part that is provided with a fixed terminal, the fixed terminal is contacting with each of the contact terminals (28, 30) to generate an operation signal, wherein the lever arm (14, 16) comprises: - a first lever arm that forms a cylindrical body extended to a predetermined length, wherein a coupling part for coupling one knob is formed at an end part of one side of the first lever arm, and wherein a protruding part for coupling one contact terminal is formed at an end part of the other side thereof; and - a second lever arm that forms a cylindrical body extended to a predetermined length that can house by penetrating the first lever arm to the inside thereof, wherein a coupling part for coupling another knob is formed at an end part of one side of the second lever arm, and wherein a protruding part for coupling the remaining contact terminal is formed at an end part of the other side thereof, characterized in that - a plate-shaped ring arm holder for preventing interference due to a contact between the first lever arm and the second lever arm is fixed to a coupling part of the lever holder at an end part side of the lever holder adjacent to the protruding part of the lever arms (14, 16) and provided with a hole for penetrating one end portion of the first lever arm. - a lever body having a plurality of knobs (6, 8) that perform a rotation manipulation in order to 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;
