That is, as shown in FIG. 9, the push switch actuation terminal 3223 has a push switch actuation terminal center 3223a, a push switch actuation terminal connection part 3223b, and a push switch actuation terminal extension 3223c. . Push switch enable terminal center 3223a and push switch enable terminal extension 3223c are connected to respective ends of push switch enable terminal connection 3223b. The push switch movable terminal center 3223a is implemented in a ring type, and the push switch movable terminal connection part 3223b is disposed on the outer circumference of the push switch movable terminal center 3223a. The push switch actuation terminal connection part 3223b is formed radially extending from the outer circumference of the push switch actuation terminal center 3223a, that is, the other end of the push switch actuation terminal connection part 3223b is the push switch actuation terminal extension part 3223c. Connected with The push switch movable terminal extension part 3223c has one end connected to an end of the push switch movable terminal connecting part 3223b and the other end formed as a free end, and the push switch movable terminal center 3223a is in a plane parallel to the printed circuit board 200. The spiral type toward the outer side and toward the push switch fixing terminal 3225 when viewed in the longitudinal direction of the rotary shaft 3120.

That is, the push switch movable terminal extension part 3223c is connected to the end of the push switch movable terminal connection part 3223b to have a structure extending in a spiral type toward the outside, thereby implementing a predetermined stable push switching function. That is, when the push knob 3210 is pressed by the user, the push knob 3210 makes a relative vertical movement with respect to the rotary knob 3110, and the push switch movable part 3221 disposed under the push knob 3210. The push knob 3210 and the push switch movable part 3221 together form a downward movement toward the lower printed circuit board 200. At this time, the push switch movable terminal extension part 3223c disposed on the lower surface of the push knob 3210 may transmit a pressing force through a connection with the push switch movable terminal connection part 3223b to form a downward movement state. The push switch movable terminal extension portion 3223c and the push switch fixing terminal 3225 in which the contact state is released in a normal state, that is, without an external force applied, form a contact state with each other to generate a change in a predetermined electrical signal.

In this case, the push switch 3220 further includes a push switch elastic portion 3227, and the push switch elastic portion 3227 has one end of the push switch movable terminal 3223, more specifically, of the push switch movable terminal center 3223a. The lower end is supported by the lower end and the other end is supported by the rotary shaft 3120, more specifically, the lower end of the rotary shaft base center 3123a of the rotary shaft base 3123 and one end surface of the rotary shaft base bridge 3123b. Accordingly, the push switch elastic part 3227 serves to elastically support the push switch actuating terminal 3223, so that when the external force applied to the push knob 3210 is removed by the user, the push switch actuating terminal 3223 is removed. By returning to the original position, the state of contact with the push switch fixing terminal 3225 is released to thereby form the original state of the electrical signal.

On the other hand, the rotary switch unit 3100 of the switch composite 300 of the present invention may further include a configuration for preventing the slip between the rotary knob 3110 and the rotary shaft 3120 to achieve a smooth rotary rotation operation. That is, as shown in FIGS. 3 and 6, a rotary knob shaft connection part 3119 extending toward the rotary shaft 3120 is disposed at the lower end of the rotary knob 3110, and a rotary knob shaft connection part is disposed on the rotary shaft 3120. A shaft accommodating portion 3122 is formed to accommodate the 3119, the shaft accommodating portion 3122 is formed in a hollow type at one end of the rotary shaft body 3121, and the rotary knob shaft connecting portion 3119 is the shaft accommodating portion 3122. Is accommodated in). In this case, a component for preventing relative rotation may be further provided between the rotary knob shaft connection part 3119 and the shaft accommodating part 3122. That is, the connecting portion guide 3118 is disposed on the outer circumference of the rotary knob shaft connecting portion 3119, and the connecting portion guide 3118 of the rotary knob shaft connecting portion 3119 is located inside the shaft receiving portion 3122 of the rotary shaft 3120. The rotary shaft body guide 3127 is disposed at a corresponding position, and the connection guide 3118 and the rotary shaft body guide 3127 are engaged with each other. In this embodiment, the connection guide 3118 has a protrusion structure and the rotary shaft body guide 3127 has a recess structure, which forms an interlocking structure, thereby ultimately rotating relative between the rotary knob 3110 and the rotary shaft 3120. Can be prevented.

In addition, a vertical stopper 3126 is disposed inside the shaft accommodating portion 3122 of the rotary shaft 3120. The vertical stopper 3126 protrudes from the inner surface of the shaft receiving portion 3122 formed in the hollow type on the rotary shaft 3120. The vertical stopper 3126 formed in the protruding shape of the rotary knob shaft connection portion 3119 The rotary knob 3110 is pressed against the other components by limiting the vertical movement of the rotary knob 3110 by preventing the excessive entry of the rotary knob shaft connection 3119 into the shaft receiving portion 3122 in contact with the lower end thereof. The interference of may be prevented from occurring.

The above embodiments are examples for describing the present invention, but the present invention is not limited thereto. For example, a separate optical display unit for outputting light according to the individual switching operation included in the composite switch unit according to the present invention may be further provided. Various configurations are possible in the range of forming a complex switching structure to enable the.
