PURPOSE:To reduce the number of switches, by which control objects of respective devices are selected, to make it possible to control selectively them simply and rapidly, by providing select switches and master switches as prescribed. CONSTITUTION:Select switches 1G-NG are provided correspondingly to plural devices. Place switching master switches 51A and 51B which switch, for example, the center and the field, master switches 61A and 61B for control method which switch, for example, manual operations and automatic operations, master switches 71A and 71B for control system which switch, for example, a variable speed and a fixed speed, master switches 81A and 81B which switch the control on operation and the control off operation, etc., are provided. Respective master switches are provided commonly to select switches 1G-NG. Consequently, it is unnecessary to provide a select switch for every control object of each device, so that the number of switches can be reduced. As the result, devices can be selectively controlled simply and rapidly. |
