Description of the Related Art As the above-mentioned switch device, as shown in, for example, Japanese Utility Model Publication No. 1-17057, a switch body, a slider for activating the switch body, a neutral return mechanism, etc. There is known a structure in which related parts of (3) are incorporated, a shaft body protruding from a slider is projected to the outside of the case, and an operation knob is fitted and connected to the shaft body.

[0003]

However, in the above-mentioned conventional device, when different types of built-in switch bodies are used in the switch devices of different models, the heights of the switch bodies are different, and therefore the same case is used. If the sliders of the same construction are used, the slider and the actuator of the built-in switch cannot be interlocked and coupled, and therefore, different forms for each switch device, namely,
Cases having different height dimensions had to be manufactured and used. Further, it is conceivable to change the slider structure, but in that case, the operation knob and the like had to be changed accordingly. As a result, the manufacturing efficiency is poor and the cost of the product is increased.

An object of the present invention is to make it possible to share a case when manufacturing a switch device of another model having a different built-in switch body, thereby improving manufacturing efficiency and reducing costs.

[0005]

In order to achieve the above object, the present invention has the following constitution.

The switch body actuator housed in the case and the operation knob arranged outside the case are
A switch device interlockingly connected via a slider mounted through a case, wherein the slider is an external slider provided outside the case, and the switch body provided inside the case. And an internal slider interlockingly connected to the actuator, wherein the external slider and the internal slider are engaged and connected through an operation hole of the case, and the operation knob is connected to the external slider. .

[0007]

When manufacturing various types of switch devices having different switch main bodies, only the inner slider can be made different depending on the height of the switch main body. This allows the case to be shared.
