The switch knob (3), consisting of a rotary switch housing (2) coupled to the connector terminal (B) and a funnel-shaped transparent material seats the components inserted into the rotary switch housing (2) in order to be inserted in sequence. A funnel-shaped serration lens (4) having stepped serrations (4a, 4b) formed at the light inlet and the edge portion so as to be bent into the switch knob (3) to simultaneously bend the light emitted from the light source (8). ), A transparent lens 5 made of a transparent material surrounding the rotary switch housing 2, a handle made of a milky white translucent material forming an overall appearance while the transparent lens 5 is inserted to be illuminated through the transparent lens 5. And a push button 7 for operating the switch provided on the PCB on which the LED 8 is mounted by moving the switch knob 3 when it is pressed into the handle 6.

That is, the composite rotary switch 1 of the present invention, as shown in Figure 3, the rotary switch housing 2 is coupled to the connector terminal (B) is inserted into the PCB substrate and fixed, funnel-shaped serration lens When one end of the switch knob 3 having the same shape is inserted into the rotary switch housing 2 so that the 4 is inserted into the inside, the transparent lens 5 is inserted into the outer surface of the rotary switch housing 2 and the switch is When the transparent lens 5 is inserted into the insertion groove formed in the rim of the handle 6 provided with the push button 7, which is pressed to cover the knob 3, the overall composite rotary switch 1 Will be assembled.
