PURPOSE:To confirm full open and full close easily and correctly with one indicator by connecting a controller to an input means, the indicator, a plurality of switches, and a plurality of detectors. CONSTITUTION:An input means 17 receives a signal and transmits its information to a controller 21. The controller 21 receives the signal and drives a plurality of switches 19 at a time. A plurality of electrically driven switching devices 16 are thus opened, closed, and stopped at a time. Detectors 20 connected to each of the electric switch bodies 16 detect the conditions of the switching devices 16 and, when they are fully opened or fully closed, transmit the information to the judgment part 22 of the controller 21. The judgment part 22 inspects whether or not all the detectors 20 detect full open or full close and, only when it judges that all the detectors do, drives an indicator 18 to indicate full open or full close. |
