Abstract:
1. A haptic steering wheel switch apparatus comprising: A haptic wheel housing unit disposed on a steering wheel of a vehicle; A circuit board unit disposed in the haptic wheel housing unit, A haptic wheel device unit including a haptic wheel device actuator establishing an electrical connection with the circuit board unit and including a haptic shaft, a haptic knob connected to the haptic shaft and exposedly disposed on one surface of the haptic wheel housing unit, and a haptic wheel device sensing unit for detecting a rotating state of the haptic shaft, The haptic knob is rotatable on a plane formed by the steering wheel of the vehicle and is allowed to be pressed and movable in a vertical direction that is perpendicular to the plane, The haptic shaft is connected with the haptic knob, wherein, when the haptic knob rotates about a rotational axis, the haptic shaft rotates about the same rotational axis, According to a movement of the haptic knob in said vertical direction, the haptic wheel device actuator moves in said vertical direction, A button switch unit provided outside the haptic knob, the button switch unit operating vertically and independently of the haptic knob, Wherein the button switch unit further comprises a button light source unit disposed on the circuit board unit, and the button guide is formed of a light guide material, Wherein the button light source unit comprises a first wavelength light source for outputting a first wavelength light and a second wavelength light source for outputting a second wavelength light of a wavelength band different from a wavelength band of the first wavelength light, and the button switch unit further comprises a button optical filter unit for selectively passing the first wavelength light or the second wavelength light and indicating a variable symbol by changing an output region of light depending on an operation of the button light source unit.
