2. Description of the Related Art For example, as a switch device used in a window regulator of an automobile, there is a switch device composed of two sets of a main switch device provided on a driver's seat side and a sub switch device provided on a door side. Generally, when these switch devices are operated, the motor for raising and lowering the window is energized and rotates forward or backward, and the window moves up or down. Further, these switch devices are provided with a light emitting diode for illuminating an operation knob, and are supplied with power when the vehicle is in use and are always lit.

In general, this type of conventional switch device is generally formed by insert-molding a plurality of power-supply-side and load-side terminals on a base, similar to an auxiliary terminal for supplying power to a light-emitting diode.
