PURPOSE:To prevent an operation error of the operation switch, by confirming the operation switch to be operated, according to a selective signal which is output from the operation switch for controlling the apparatus to be controlled. CONSTITUTION:Apart from the function for providing a control signal to the apparatus to be controlled, the function for outputting a selective signal is added individually to the operation switches 3A, 3B. For instance, by gripping the lever 5a of the handle 5 provided to the selective switch body 4, the selective signal S1 is output, and the lamp 7Y provided corresponding to a desired apparatus to be controlled is turned on. By means of this display, it can be confirmed that said switch is the operation switch of the desired apparatus to be controlled. And, after confirmation, the control signal S2 is output by turning the handle 5. In this way, an operation error of the operation switch can be prevented. |
