The head portion 241 may be configured such that light passing through the optical path is switched by interposing the light reflecting means and the outer peripheral surface of the head portion 241 is formed in a polygonal shape so that light can pass through only a certain region. On the other hand, the through-hole formed in the base of the third seating part 254 is located at a position opposite to the second signal generating part 270.

When the LED 282 of the light emitting means 280 irradiates light, the light passes through the optical path of the shaft portion 242 of the light guide portion 240 and is turned by the head portion 241, When the user rotates the wheel knob 230, the light is reflected by the plurality of light receiving means 271 and 272 of the second signal generator 270 according to a specific order A signal is generated.

The structure in which the signal is inputted by the rotation of the wheel knob 230 is implemented by the non-contact type structure including the light emitting means 280 and the light receiving means 271 and 272. In the structure in which the wheel knob assembly is depressed So that it is possible to smoothly implement the operation. Therefore, it is meaningful to simultaneously construct the second signal by generating the first signal by the descent by the hinge connection part and by using the light emission and the light reception by the rotational motion.

The composite switch 100 according to the present embodiment includes a rotation function for transmitting non-contact sensing through the inner space of the wheel knob 230 in which the light generated by the light emitting means 280 is rotated, The holder 250 coupled to the first wheel 230 contacts the first signal generator 290 on the main PCB 260 to directly transmit a signal so that the flow of the wheel knob assembly is suppressed and the downward movement of the wheel knob 230 And can be configured with a simple structure in which stable operation is improved.

In addition, a non-contact sensing can be performed by forming a transmission structure inside the wheel knob 230 to send light to the opposite side. A reaction force is applied to the inner side of the wheel knob 230 to utilize the cam 210 The click feeling can be obtained.
