Abstract
The invention provides a switching device. A switching device is constructed by including a wheel and two switches. The switching device has not only a rotary shaft of the wheel but also another rotary shaft. The rotary shaft of the wheel is provided with a rotary encoder. As shown by an arrow, by rotating the wheel about the rotary shaft with a finger or the like, a predetermined item is selected. By inclining the wheel about the another rotary shaft as shown by an arrow, the switches can be turned on/off. With the configuration, the switching operation can be performed with reliability.
