The bottom surface of the base 110 is provided with a plate-shaped elastic member 130 having a predetermined elastic restoring force, the second through hole 131 is formed in the center of the elastic member 130. Although the shape of the elastic member 130 is shown in a disk shape in the figure, the present invention is not limited to the shape.

One region in the plate-shaped interior of the elastic member 130 is cut to form a first elastic arm portion 132 protruding toward the base 110 side, and another region in the plate-shaped interior of the same elastic member 130 is cut and first. A second elastic arm 133 protruding in the opposite direction to the elastic arm 132 is formed. The first elastic arm 132 and the second elastic arm 133 are preferably formed in a symmetrical position with respect to the second through hole 131, but the present invention is not limited thereto.

The first elastic arm 132 is formed in a convex shape protruding toward the base 110, and this convex shape corresponds to the shape of the valley 114 of the click feeling generating unit 115 of the base 110 described above.

The second elastic arm 133 includes one or more contact parts 134 that are bent toward the circuit board 200, and the contact parts 134 are electrically connected to the plurality of circuit wires 151 formed on the circuit board 150. Can be contacted.

In the present embodiment, since the elastic member 130 itself is formed of a conductive metal plate, the first elastic arm part 132 and the second elastic arm part 133 formed by cutting the conductive metal plate are also conductive. Therefore, since the contact portion 134 of the second elastic arm portion 133 is also conductive, it can be electrically connected to the circuit wiring 151.

Of course, the present invention is not limited thereto. Although the elastic member 130 itself is non-conductive, the entire elastic member 130 may be plated with a conductive material. Alternatively, only the first and second elastic arm parts 132 and 133 may be plated with a conductive material separately, and at least the second elastic arm part 133 may be plated with various modifications.

Various modifications are possible, such as using a bolt and nut coupling method by forming the formed nut.

The operation of the rotary mode switching device 100 configured as described above will be briefly described.

When the user rotates the handle member 120 in one direction to change a predetermined mode of the digital device (not shown), the elastic member 130 rotates together with the rotation of the handle member 120.

As the handle member 120 rotates, the convex first elastic arm part 132 formed on one side of the elastic member 130 also rotates together, such that the first elastic arm part 132 clicks on the base 110. It moves along the sense generator 115.

When the convex first elastic arm portion 132 is disposed at the position of the valley 114 of the click feeling generation unit 115, the first elastic arm portion 132 may stably maintain the stationary state.

When the convex shape of the first elastic arm portion 132 is moved to the position of the peak 113 of the click feeling generating portion 115 by the rotation of the handle member 120, an interval at which the first elastic arm portion 132 is located is located. Since it becomes narrow, the 1st elastic arm part 132 will be in the pressed state. At this time, if the convex shape of the first elastic arm portion 132 is moved to the position of the next bone of the click feeling generating portion 115 by continuing the movement of the first elastic arm portion 132, the first elastic arm portion by the elastic restoring force 132 is restored to the original shape by the restoring force to maintain a stable stationary state again, and the user can obtain a feeling of click.

In addition, the second elastic arm 133 formed on the other side of the elastic member 130 also rotates along with the rotation of the handle member 120, thereby moving on the circuit board 150.

Each time the contact portion 134 of the second elastic arm portion 133 contacts the plurality of circuit wires 151 of the circuit board 150 by movement, the mode is switched.

That is, as the handle member 120 rotates, the elastic member 130 rotates together, and the first elastic arm part 132 formed on one side of the elastic member 130 is in contact with the bottom surface of the base 110. Whenever a click feeling occurs while moving along the peak 113 and the valley 114 of the generator 112, the second elastic arm 133 formed on the other side of the elastic member 130 may be formed on the circuit board 150. Mode switching occurs while repeating contact and disconnection with the circuit wiring 151 while moving in contact with the upper surface. At this time, it is preferable that one mode is switched every time a feeling of click occurs.

According to the rotary mode switching device and the digital device including the same according to the present invention, the first elastic arm portion for generating a click feeling and the second elastic arm portion for the mode switching signal are formed by cutting on the same elastic member on the plate This reduces the number of parts, which simplifies the manufacturing process. In addition, it enables the production of thin products due to the reduced number of parts.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true scope of protection of the present invention should be defined by the technical spirit of the appended claims.
