In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a perspective view illustrating a switch device according to an embodiment of the present invention, FIG. 2 is an exploded perspective view illustrating a switch device according to an embodiment of the present invention, FIG. 3 is a cross- And the second switch is installed in the operation guide of the push button module in the switch device.

1 to 3, a switch device according to an embodiment of the present invention includes a circuit board 110, a holder housing 120, a guide housing 130, and an operation button module 140.

The circuit board 110 is provided with a first switch 113 and a second switch 115. At this time, the first switch 113 is mounted on one side of the circuit board 110 and the second switch 115 is mounted on the other side of the circuit board 110. The first switch 113 and the second switch 115 may be mounted on one side of the circuit board 110. The first switch 113 and the second switch 115 are connected to a wiring pattern (not shown) of the circuit board 110.

A tact switch for transmitting a driving signal to the wiring pattern of the circuit board 110 as the first switch 113 is pressed can be applied. The tact switch is contracted as it is pressed and restored to its original state as the pressing force is released. Since the tact switch is applied to the circuit board 110, the manufacturing cost of the switch device can be reduced.

The second switch 115 may be a contact switch that transmits a drive signal to the wiring pattern of the circuit board 110 when the operation button module 140 is contacted. The contact switch is a switch that is not contracted or deformed when the operation button module 140 is contacted. Contact portions 115a and 115b are formed on the second switch so as to detect that the operation button module 140 is contacted. The contact portions 115a and 115b include a first contact portion 115a and a second contact portion 115b.

The contact portions 115a and 115b of the second switch 155 are disposed inside the through hole portion 111. [ Accordingly, when the operation button module 140 is rotated while passing through the through-hole portion 111, the operation button module 140 can be brought into contact with the second switch 115.

The circuit board 110 is formed with a through hole 111 so that the operation button module 140 passes through the circuit board 110. The first switch 113 is disposed on one side of the circuit board 110 and the second switch 115 is operated The button module 140 is disposed at the periphery of the through-hole portion 111 so as to contact the operation button module 140 as the button module 140 is rotated. The first switch 113 is mounted on one side of the circuit board 110 and the second switch 115 is mounted on the other side of the circuit board 110. Since the first switch 113 and the second switch 115 are dispersedly mounted on one surface and the other surface of the circuit board 110, the installation area of the switch on the circuit board 110 can be reduced. The area of the circuit board 110 where the switch device is provided can be reduced, and the degree of integration of the circuit board 110 can be increased.

The circuit board 110 is formed with a number of through holes 111 corresponding to the number of switch devices to be mounted. For example, when two switching devices are provided on the circuit board 110, two through-hole portions 111 are formed in the circuit board 110.

The holder housing 120 is installed on one side of the circuit board 110. Both sides of the holder housing 120 are formed to be open. The holder housing 120 may be formed in a polygonal or cylindrical shape. The holder housing 120 is provided with one or more guide housings 130.

FIG. 4 is a perspective view illustrating a state where a guide housing and an operation guide are assembled in a switch device according to an embodiment of the present invention, FIG. 5 is a sectional view showing a switch device according to an embodiment of the present invention, FIG. 7 is a sectional view of a switch device according to an embodiment of the present invention. FIG. 7 is a cross-sectional view of a switch device according to an embodiment of the present invention. Sectional view showing a state of engagement of the switch.

4 to 7, the guide housing 130 is movably installed inside the holder housing 120, and presses the first switch 113 as it moves toward the circuit board 110 side. At this time, the guide housing 130 is installed in the holder housing 120 so as to be movable in a direction perpendicular to the circuit board 110. The first switch 113 is pressed as the operation button module 140 and the guide housing 130 are simultaneously moved toward the circuit board 110 so that the switch device can be operated as a push switch type.

A guide portion 132 is formed in the guide housing 130 so that the guide housing 130 can be moved to the holder housing 120. [ A plurality of guide portions 132 are formed on the outer surface of the guide housing 130. At this time, the guide part 132 protrudes from the outer surface of the guide housing 130, and the guide groove part 122 is formed in the holder housing 120 so that the guide part 132 slidably fits. The guide portion 132 is formed to be parallel to the direction perpendicular to the circuit board 110. Since the guide housing 130 is movably installed in the holder housing 120 by the guide portion 132, the guide housing 130 can be moved with almost no shaking.

A pressing rod 133 is formed in the guide housing 130 so as to press the first switch 113 when the guide housing 130 is moved toward the circuit board 110. The pressing rod 133 is elongated to be parallel to the moving direction of the guide housing 130. When the pressing rod 133 presses the first switch 113, a signal generated by the first switch 113 is transmitted along the circuit wiring. When the external force acting on the guide housing 130 is released, as the restoring force of the first switch 133 acts on the pressing rod 133, the guide housing 130 is raised to the original position. The pressing rod 133 may be formed in various shapes.

The operation button module 140 is rotatably installed in the guide housing 130 and is moved toward the circuit board 110 together with the guide housing 130. At this time, the operation button module 140 is seesawably installed in the guide housing 130.

The operation button module 140 includes a button portion 141 and an operation guide 144. The button portion 141 is disposed on one side of the holder housing 120. The operation guide 144 is coupled to the button portion 141 and is rotatably coupled to the guide housing 130. When the operation guide 144 is moved toward the through hole portion 111 side together with the guide housing 130, the second switch 115 is separated from the second switch 115 and contacts the second switch 115 when the operation guide 144 is rotated by the guide housing 130 . Accordingly, a plurality of switches can be operated as the operation button module 140 is driven by the push switch type and the tumbler type.

Since the through hole portion 111 is formed in the circuit board 110 and the operation button module 140 is installed to pass through the through hole portion 111, the other side of the circuit board 110 Lt; RTI ID = 0.0 > 115 < / RTI > Therefore, it is not necessary to provide a separate structure on the other side of the circuit board 110 so that the second switch 115 can be operated. Therefore, the structure of the switch device is simplified, and the size of the switch device can be reduced.

The operation guide 144 includes a rotation part 145 and a guide plate 147. The rotation part 145 is rotatably coupled to the guide housing 130. The guide plate 147 is extended from the rotation part 145 to pass through the through hole part 111 and the guide slot 148 is formed so as to be spaced apart from the second switch 115 when moved to the through hole part 111 side. Accordingly, when the operation button module 140 is moved toward the through hole portion 111, the second switch 115 does not contact the operation guide 144. [

A first contact rib 147a and a second contact rib 147b are formed at the ends of the operation guide 144 so as to contact the contact portions 115a and 115b of the second switch 115 on both sides of the guide slot 148 . When the operation button module 140 is rotated to one side, the first contact rib 147a contacts the first contact portion 115a of the second switch 115. [ When the operation button module 140 is rotated to the other side, the second contact rib 147b contacts the second contact portion 115b of the second switch 115. [

A hinge hole 137 is formed on both sides of the rotation part 145 and a hinge hole 146 is formed on both sides of the guide housing 130 so that the hinge part 137 of the rotation part 145 is inserted. The guide plate 147 is formed to be parallel to the moving direction of the guide housing 130. The guide slot 148 is formed to be parallel to the moving direction of the operation guide 144. The second switch 115 is not brought into contact with the operation guide 144 even if the operation guide 144 is moved toward the through hole portion 111 because the guide slot 148 is formed to be parallel to the moving direction of the operation guide 144 .

When the button portion 141 is pressed sideways, the operation guide 144 is laterally rotated about the hinge portion 137. The contact portions 115a and 115b of the second switch 115 are relatively moved along the guide slot 148 when the operation guide 144 is moved toward the circuit board 110 side. Therefore, it is possible to prevent the second switch 115 from being operated even when the operation guide 144 is pressed.

The switch device further includes a flow prevention part 150 disposed between the operation button module 140 and the guide housing 130 and supporting the operation button module 140 by an elastic force. At this time, the operation button module 140 and the guide housing 130 are spaced apart from each other by a predetermined distance. Since the flow prevention portion 150 supports the operation button module 140 by the elastic force, the operation button module 140 is fixed in position so as not to shake. Therefore, it is possible to prevent the operation button module 140 from swaying sideways when the operation button module 140 is pressed toward the circuit board 110 side.

The flow prevention unit 150 includes an elastic member 151 supported on the guide housing 130 and an elastic member 151 coupled to the operation button module 140 to push the operation button module 140, And a push cap 153 for transmitting the elastic force of the push cap 151. Since the elastic member 151 exerts an elastic force to push the operation button module 140, the operation button module 140 can be held in place and flow can be prevented. In addition, when the external force applied to the operation button module 140 is removed, the operation button module 140 can be returned to the original position by the elastic force of the elastic member 151.

The light irradiation part 117 is mounted on one side of the circuit board 110 so as to irradiate light as the first switch 113 and the second switch 115 are operated. The light guide part 135 is formed in the guide housing 130 so that the light of the light applying part 117 can be irradiated to the upper side of the operation button module 140. A light emitting device (LED) may be applied to the light irradiating unit 117. The operation guide 144 of the operation button module 140 for pressing the second switch 115 is arranged so as to pass through the through hole portion 111 because the second switch 115 is mounted on the other side of the circuit board 110 do. Therefore, it is possible to secure a sufficient space for forming the light path portion 135 inside the guide housing 130.

The operation button module 140 is formed with a display portion 142 to be illuminated by the light irradiated from the light irradiation portion 117. Accordingly, as the switches 113 and 115 are operated, the display unit 142 can be illuminated with the corresponding pattern. The selected function can be recognized as the pattern of the display unit 142 is illuminated.

The switch device further includes a display unit 170 connected to the circuit board 110 and displaying driving information as the first switch 113 and the second switch 115 are pressed. Since the driving information of the apparatus is displayed on the display unit 170, the user can accurately recognize the driving state of the apparatus.

Operation of the switch device according to an embodiment of the present invention will now be described.

FIG. 8 is a cross-sectional view illustrating a state in which the operation button module of the switch device according to the embodiment of the present invention is rotated to one side and contacts the second switch, FIG. 9 is a cross- FIG. 10 is a perspective view illustrating a state in which the operation button module is rotated to one side and is in contact with the second switch. FIG. 10 is a perspective view of the switch device according to the embodiment of the present invention, 11 is a perspective view illustrating a state in which the operation button module is in contact with the second switch as the operation button module is rotated to the other side in the switch device according to the embodiment of the present invention.

8 to 11, when the button part 141 is rotated to one side, the rotation part 145 of the operation guide 144 is rotated in one direction about the hinge part 137 in the guide housing 130. [ As the operation guide 144 is rotated, the guide plate 147 of the operation guide 144 is inclined. At this time, the first contact portion 115a of the guide plate 147 is brought into contact with the first contact portion 115a of the second switch 115. When the rotation part 145 of the operation guide 144 is rotated to the other side around the hinge part 137, the second contact part 115b of the guide plate 147 contacts the second contact part 115b of the second switch . When the operation button module 140 is rotated, since the operation guide 144 is rotated with the second switch 115, the switch device can be operated as a tumbler switch type.

When the second switch 115 is operated, power is supplied to the light irradiation unit 117 by the control unit of the circuit board 110. The light irradiated from the light irradiating portion 117 reaches the display portion 142 through the light path portion 135 (see Fig. 10). Therefore, since the display section 142 is illuminated, the selected function can be confirmed.

12 is a cross-sectional view illustrating a state in which the first switch is pressed as the operation button module is moved to the circuit board side in the switch device according to the embodiment of the present invention.

12, when the button portion 141 is pressed toward the circuit board 110, the operation guide 144 and the guide housing 130 are moved toward the circuit board 110 by the pressing force of the button portion 141 . The pressing rod 133 of the guide housing 130 presses the first switch 113 of the circuit board 110 as the guide housing 130 moves toward the circuit board 110. [ At this time, since the guide slot 148 is formed in the guide plate 147 of the operation guide 144, the operation guide 144 is separated from the second switch 115 even if the operation guide 144 is lowered together with the guide housing 130. Therefore, since the operation guide 144 does not contact the second switch 115, it is possible to prevent the first switch 113 and the second switch 115 from operating at the same time. When the button portion 141 is moved toward the circuit board 110 side, the operation guide 144 presses the first switch 113, so that the switch device can be operated as a push switch type.

When the first switch 113 is pressed, power is supplied to the light irradiation unit 117 by the control unit of the circuit board 110. The light irradiated from the light irradiating portion 117 reaches the display portion 142 through the light path portion 135. Therefore, since the display section 142 is illuminated, the selected function can be confirmed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.
