Switch device of car {SWITCH APPARATUS FOR AN AUTOMOBILE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device for an automobile, and more particularly to a switch device for an automobile in which a drainage structure is formed.

In general, various switch devices are installed in an interior of a vehicle, and the types of switches are variously classified according to the operation method of a knob provided in a switch signal input unit. And a push switch device for generating a different switch signal according to the present invention, and the knob being rotated in one direction about a rotation center of which the knob is disposed horizontally to generate a first switch signal, and being rotated in another direction to generate a second switch signal. Typical examples are a switch device and a rotary switch device in which the knob is rotated about a rotation axis to generate different switch signals according to the rotation angle of the knob.

The rotary switch device may be classified into a dial switch device, a joystick switch device, a scroll switch device, and the like according to the shape of the knob.

In addition, although the above-described switch devices have been a mechanical input method in which a user applies a predetermined force to a switch method, a recent development of a touch type switch device operated according to a user's touch input has been actively developed. .

The touch switch device includes a capacitive touch pad configured to be touched by a user with a finger, and the capacitive touch pad is touched by the user to input a touch signal.

On the other hand, the switch devices are a PCB (printed circuit board) which is a part which is directly manipulated by a user's finger, a switch body in which the knob is installed, and a switch signal installed in the switch body to generate a switch signal according to the manipulation of the knob. ).

However, when moisture is introduced into the switch body, the PCB, which is a electrical component, may cause malfunction and failure by the introduced moisture.

Accordingly, the switch devices have a drainage structure such that moisture introduced into the switch body is discharged into the switch body without passing through the PCB. However, in the conventional drainage structure, drainage holes and inclined ribs are formed in the switch body so that water introduced into the switch body is drained out of the circumference of the PCB, thereby increasing the size of the switch body. there was.

In particular, when a plurality of switch devices are integrally installed in one switch body, since space is restricted for installing the plurality of switch devices in the switch body, space for securing the drainage structure is insufficient. There was also.

In addition, a mood ring that emits light by a light source provided in the PCB is installed at an outer circumference of the knob, so that the user can easily recognize the position of the knob through the light emitted by the light with soft light. Emotion can be improved.

However, in the switch device according to the related art, since the drainage structure is not formed in the mood ring itself, there is a problem that moisture flows into the PCB through the mood ring.

The problem to be solved by the present invention is to provide a switch device for an automobile in which the drain ring structure is formed in the mood ring itself.
