The present invention according to claim 1 selects a function by touching a function switch displayed on a touch panel, and further presses the function switch to turn on the function to determine the function. In the touch panel composite switch, the function switch selected before the predetermined time when the touch panel is turned on is set as an effective selection switch.

Therefore, when the function switch displayed on the touch panel is touched to select the function and then the function switch is further pushed to determine the function, the finger is displaced from the selected function switch. Even when the function switch is touched, the function switch selected before the predetermined time when the function is determined is set as the effective selection switch. Therefore, the function switch selected first can be reliably determined. As a result, by enabling a reliable touch operation, it is possible to improve the suitability for mounting on a vehicle.

According to a second aspect of the present invention, there is provided a touch panel composite switch for selecting a function by touching a function switch displayed on the touch panel, and further pressing the function switch to turn on the switch to determine the function. When a plurality of function switches are touched within a predetermined time before being turned on, the function switch having the longest contact time among the plurality of function switches is set as an effective selection switch.

Therefore, when the function switch displayed on the touch panel is touched to select the function and then the function switch is further pushed to determine the function, the finger is displaced from the selected function switch. Even when the function switch is touched, the function switch having the longest contact time among the plurality of contacted function switches is set as the effective selection switch. Therefore, it is possible to surely determine the function switch that is intentionally selected. As a result, by enabling a reliable touch operation, it is possible to improve the suitability for mounting on a vehicle.
