BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunction switch device for use in navigation or audio systems, and more particularly, to a multifunction switch device for quickly and conveniently operating various functions with one switch.

In general, the multi-function switch device is applied to a navigation system or an audio system of a vehicle, and is made to enable multiple switch operations with a single switch device.

Such a multi-function switch device is composed of a set of joystick switch, push switch, rotary switch and the like.

1 is a cross-sectional view showing a conventional multifunction switch device, through which looks at the conventional multifunction switch device.

First, the push switch operation will be described. When the push / joystick knob 1 located at the top is pushed in the vertical direction, the first shaft 5 located at the center of the switch case 3 descends while the second shaft ( 7) will be pressed. At this time, the push contact 9 is in contact with the switch terminal provided on the PCB 11 by the displacement of the second shaft 7, the ON operation of the push switch is made.

Next, the joystick switch operation will be described. When the push / joystick knob 1 is moved in eight directions such as the front, back, left, right, and diagonal directions with respect to the center, the first shaft 5 The joystick lever 13 arranged in a double axial structure around the inclined direction moves in the same direction as the push / joystick knob, and at this time, the push unit 15 extending from the joystick lever 13 in four directions is pushed ( While pressing 17), a switch operation is made while pressing one of four push contacts 17 or two push contacts 17 at the same time.

That is, when the push / joystick knob 1 is moved in the up, down, left, and right directions, two push contacts 17 are simultaneously pressed, and the push / joystick knob 1 is moved in the diagonal direction. In this case, the switch operation is made while pressing one push contact 17.

Meanwhile, a detent mechanism 19 is provided around the upper side of the joystick lever 13 to perform a positioning function and a return function when the joystick switch is operated.

Next, the rotary switch operation will be described. When the rotary knob 21 located below the push / joystick knob 1 is rotated, the rotary rotary bodies 23 rotate together along the rotary knob 21. Switch operation is made by changing the rotary switch 25.

Conventional multifunction switch device as described above is made to be able to operate a variety of switches in a joystick method, a push method, a rotary method and the like.

The switch circuit is changed in electrical contact with the provided switch circuit.

In this case, when the push / joystick knob 50 is moved in the up, down, left, and right directions, two switch pointers 96 located on both sides of the push / joystick knob 50 are simultaneously pressed, and the push / joystick knob 50 is pressed. When moving in the diagonal direction, the switch operation is made while pressing one switch pointer 96.

In addition, the push / joystick knob 50 moves in eight directions, and the detent mechanism 75 provided around the shaft 70 guides the correct movement direction of the push / joystick knob 50. When the user removes the force applied to the push / joystick knob 50, the shaft 70 returns to its original position by the interaction of the detent pin 77 and the detent plate 78.

Next, the rotary switch operation will be described.

When the rotary knob 60 is rotated, the rotary body 64 rotates along the rotary knob 60 while the mutual positions of the switching units 64a and 65 are changed to perform the rotary switch operation. At this time, since the positioning means 65 consisting of the spring 67 and the ball 66 gives a sense of theft, the switch is operated at the correct position.

The multi-function switch device according to the present invention configured and acted as described above has an advantage that the internal structure for transmitting the operating force of the push / joystick knob is made simpler since the shaft transmitting the operating force of the push / joystick knob is integrated into one. have.

In addition, the present invention is configured to press the pusher through the push lever separated from the shaft, so that the switch operation is performed more accurately without using a metal material for maintaining rigidity as in the prior art, the advantage of improving the reliability of the switch operation There is this.
