The rotary detent 431 is fixed to the lower side of the rotary encoder 410 and more specifically to the lower side of the rotary encoder 410 from an outer peripheral surface As shown in Fig. The rotary detents 431 may be arranged at predetermined predetermined intervals. Although not shown in the present embodiment, a rotary stopper (not shown) for preventing excessive rotation of the rotary encoder may be further provided to form a rotation restricting region, And a structure may be employed in which the rotation reference of the rotary switch sensor is initialized when the power is turned off.

Meanwhile, when such a rotary detent portion is configured to be arranged in a radial direction, the rotary detent portion may additionally implement a push return function. That is, in this case, another embodiment of the present invention may be an example of converting the push switch portion into a more compact structure, but the structure in which the rotary switch portion and the push switch portion are integrated can be formed.

The push switch portion includes a push holder 610, a push switch 620, and a push return portion 630. In this embodiment, the push switch portion includes a push switch, a push movable portion, and a push detent, In the embodiment, the return function of the push return portion is performed by the rotary detent portion together with the push-down portion, the rotary encoder slit (projection) functions as the push moving portion, and the rotary switch performs the switching detection function of the push switch together .

That is, the push moving part is vertically movable with the rotary encoder to cause a change in the signal of the push switch disposed on the substrate when the switch shaft hinge of the switch shaft part is moved downward by pressing the rotary encoder, In this embodiment, the rotary encoder slit takes charge of the function of the push moving part, and the rotary switch takes charge of the function of the push switch.

The push detent 630a is formed on the lower side of the rotary encoder 410a at the upper end of the rotary detent 431a. The push detent 630a is layered with the rotary detent 431a in the longitudinal direction of the switch shaft portion 300 and in the radial direction from the center of the switch shaft portion 300. [ That is, the plane on which the push detent 630a is disposed and the plane on which the rotary detent 431a is disposed are different from each other when viewed on a plane in which the rotation shaft of the switch shaft portion 300 passes, and the push detent 630a So that the plane in which the rotary detent 431a is disposed is disposed toward the housing cover 110 side than the plane in which the rotary detent 431a is disposed.

In this embodiment, the rotary switch 420 can additionally perform the function of the push switch. When the switch shaft portion 300 is vertically pressed through the push operation, the position of the rotary encoder slit The change causes a signal change of the rotary switch which functions as a push switch. At this time, since the on / off period of the signal through the push operation is different from the change of the on / off period of the signal in the normal rotary operation, it may be configured to detect the input state of the push operation by distinguishing it. However, this is an embodiment of the present invention, and various configurations are possible in some cases. 20 to 23, the push-switch unit and the rotary switch unit are integrated. However, the rotary encoder slit 415 may include a push switch that generates a signal change of the push switch but is further provided with a push switch separate from the rotary switch And a structure in which a separate push switch and a separate push moving part other than the push detent may be provided separately from the rotary switch and the rotary encoder slit may be adopted.

With this configuration, when the switch shaft portion 300 is vertically pressed, the lower side of the rotary encoder 410a, which moves together, contacts the rotary detent ball 433a and the rotary detent 431a The rotary detent ball 433a is released from contact with the rotary detent 431a and forms a contact state with the push detent 630a. At this time, a detent boundary 631a is formed between the rotary detent 431a and the push detent 630a, so that the user can easily detect the switching to the push operation tactily. That is, the detent boundary 631a is disposed between the rotary detent 431a and the push detent 630a to form a curvature or protrusion different from that of the rotary detent 431a and the push detent 630a, so that when switching from a normal position to a pushing operation by vertical pressing It is possible to recognize the operator through the tactile change.

In the case of the push detent 630a, the lower end portion of the rotary encoder 410 has an inclined surface arrangement structure having a predetermined curvature so as to form a state in which the vertical depressing force is removed, It can be returned to the home position. The pushing movable portion for actuating the push switch is vertically movable with the rotary encoder when at least a portion thereof is disposed at the upper end of the rotary encoder 410 and the switch shaft hinge of the switch shaft portion pushes down the rotary encoder and moves downward. The rotary encoder slit 415 assumes a configuration that replaces the function of the pushing movable part and the function of the push switch that causes the change of the electrical signal by the push moving part is performed by the rotary switch together. That is, the push switch is disposed on the substrate 200 and generates a changed signal when the push moving portion 610a is vertically displaced. As described above, in this embodiment, the push switch is connected to the rotary switch sensor 420 Respectively. In some cases, if the push switch is provided separately from the push rotary switch sensor, a separate push switch movable part may be further provided.

Further, the end of the base rotary descent receiving portion guide 131a may be provided with a structure for preventing unnecessary interference with the rotary encoder, for example, in smooth operation when the pushing operation is performed. That is, the upper end of the base toward the center of the housing base 130 is removed by the inner end of the base rotary detent receiving portion guide 131a. The guide chamfering portion 134a is chamfered, And the upper end of the base rotary descent receiving portion guide 131a is removed through the through holes 134a and 134a so that at least a part of the upper surface of the rotary detent ball 433a is exposed, It is also possible to form a contactable state.

As shown in Figs. 22 and 23, when a vertical external force is applied to the switch shaft portion, the rotary encoder 420 is vertically movable, while at the same time, pushing detent The rotary detent ball 433a is vertically moved from the contact state with the rotary detent 431 through the pushing operation so that the rotary detent ball 433a is rotated by the rotary detent 431, And the contact state with the push detent 630a is formed. In this process, the contact state is changed over the detent boundary 631a, so that a predetermined detent feeling can be provided to the operator.
