The present invention relates to a composite switch, and more particularly, to integrate a plurality of switches having a different operation form, and to simplify the structure by allowing the interior light source to simultaneously illuminate the design plate and the dial knob of the switch unit. It is about a switch.

In general, the vehicle is equipped with an air conditioner to give a comfortable feeling to the passenger by automatically adjusting the temperature and humidity of the vehicle interior air according to various changes of the surroundings and the environment of the air.

Such an air conditioner is to install and control various control switches related to the air conditioner on the control panel installed on the dash panel that the driver can easily adjust while driving.

In addition, as well as the above air conditioning apparatus, electronic devices used in homes and automobiles have been diversified and multifunctionalized. Especially, the efficient layout of various electronic devices is important around the driver's seat with limited space, and various arrangement methods have been proposed.

One of the items that is important when designing the layout is the identification of various switches that operate each electronic device, in particular the identification of the function indications of the switches.

The function display of the most common switch is to display a fixed function on the surface of the switch's operation knob. In some cases, the function cannot be displayed directly on the operation knob or the operation knob is small. .

BRIEF DESCRIPTION OF THE DRAWINGS It is an example which shows the layout of a switch as mentioned above, and is a front view which shows the control switch unit of the control panel in which the control switch which controls the air conditioner (air conditioner) of a motor vehicle is provided.

As a push switch of the said control switch unit 1, the air blower selection switch 2 of the air conditioner, the rear window defogger switch 3, the air circulation / mixing switch 4, the air conditioner switch 5, and the economy air conditioner switch 6 ), An auto mode switch 9 for automatically selecting an air blower or a flow rate selection, a release switch 10 for an auto mode, and the like are disposed.

On the other hand, as a dial switch, the temperature setting switch 7 for temperature setting, the air volume selection switch 8, etc. for selection of air volume are arrange | positioned.

Such a switch has a built-in lighting device so as to provide good identification even at night driving.

For example, the push switch turns on / off the indicator 30 on the switch knob as each of the push switches is turned ON / OFF while the design plate 20 showing the function formed on the switch knob surface is illuminated.

In addition, the dial switch has a selection target scale (temperature or air volume, etc.) disposed around it, and an indicator (guidance) 31 indicating the selection target scale is disposed on the dial knob and is illuminated.

As described above, the design plate 20 and the indicator 30 indicating the function of the switch are illuminated, thereby ensuring good identification and contributing to improvement of operability.

However, there is a problem in that the control switches of the control switch unit 1 are very unsuitable for space utilization.

In order to solve the above problems, a composite switch incorporating a push switch and a dial switch has already been developed, which is briefly described with reference to FIG. 2 as an example.

Push switch 110 having a light source 124 for illuminating the design plate formed on the surface of the switch knob 111, the inside of the hollow switch knob 111 that can be pushed down, and around the switch knob 111 A light source 124 rotating with the freely rotatable knob 120 and the dial knob 120 and illuminating an indicator 121 indicating the degree of rotation of the dial knob 120 relative to the design plate. It characterized by including a dial switch unit having.

Therefore, the design plate of the switch knob 111 is almost uniformly illuminated on the front surface without affecting other members by the light source 124 provided inside the hollow switch knob 111, and the indicator 112 is separately Is illuminated by the light source 124.

In addition, the indicator 121 of the dial knob 120 is illuminated by the light source 124 which rotates together with the dial knob 120 which is freely provided at the switch knob 111.

However, the composite switch 100 requires two separate light sources 124 to illuminate the design plate and the indicator 112 of the push switch 110, and the indicator 121 of the dial knob 120. As one light source 124 is separately required to illuminate), a separate light source 124 must be provided for each part to be illuminated.

In addition, since the respective light sources 124 have to be independently illuminated for each part, the internal structure becomes complicated as a blocker must be formed for each light source 124 in the composite switch 100 so as to prevent leakage. In addition, the manufacturing process also increases, there is a problem that the productivity is lowered.
