Description

The multifunctional composite switch is a manipulation device for interlocking with a UI (User interface) so that a graphic object can be selected.

The multifunctional composite switch recognizes the input signal by pressing, rotating, or tilting it back and forth. The input signal causes the pointing segment of the display screen to move. The pointing segment selects a selectable graphical object on the display screen and outputs an operation command.

FIG. 1 is a cross-sectional view of a conventional multifunctional composite switch. Referring to FIG. 1, a conventional multifunctional composite switch is briefly described.

First, when the push / operate switch 1 is pushed in the vertical direction, the first shaft 5 located at the center portion of the switch case 3 is lowered while the second shaft 7 The push switch 9 is brought into contact with the switch terminal provided on the PCB 11 by the displacement of the second shaft 7 and the push switch is turned ON.

In the case of the joystick switch operation, when the push / joystick knob 1 is moved in any one of the four directions in the front and rear left and right directions, the joystick lever 13 assembled around the outer periphery of the first shaft 5 moves in the corresponding direction And the pushing portion 15 extending in four directions in the joystick lever 13 presses two of the four push contacts 17 simultaneously to perform the switch operation.

The rotary switch operation is realized by rotating the rotary knob 21 disposed outside the push / joystick knob 1. [ That is, when the rotary knob 21 is rotated clockwise or counterclockwise, the rotary rotary body 23 rotates together with the rotary knob 21 to rotate the rotary rotary body 23 in accordance with the displacement of the end of the rotary rotary body 23, (25) is operated.

Reference numeral 19 denotes a detent mechanism which is provided around the upper part of the joystick lever 13 and which functions to generate a positioning function and operation feeling at the time of operation of the joystick switch and to return the same.

Such a conventional multifunctional composite switch allows various functions displayed through a display screen to be selected and executed by various operations through a single switch, thereby providing convenience of operation, Since it plays a role of preventing the concentration of power from being dispersed in advance, there is a considerable effect in achieving safe driving.

However, since the above-described conventional composite switch is a contact-type structure in which a switch connection is realized by a force transmitted to a switch through a lever or a shaft when an operation force is inputted, the structure is considerably complicated and a plurality of contact switches are required There is a problem in that it is disadvantageous in terms of mass production and cost and there is a limit in reducing the weight of the switch.

In addition, since the push contact 9 for implementing the push switch operation is provided on the in-case PCB 11 far from the knob 1, malfunction may occur in the push switch operation, 21 are rotated integrally with each other, there is a structural problem that it is difficult to apply illumination to the dial knob.
