The plug body 31 includes: an operation lever 43 which is attachable/detachable to/from the base member 30 and operated in power supply cutoff; and a conduction member 41 which is electrically conducted with the terminals 36a and 36b while being fitted to the base member 30. The display 32 that functions as notification means is connected to a notification circuit 33. When operating the operation lever 43 for a power supply cutoff operation, if contactors 25 and 28 of the power supply circuit 20 are still turned on and the power supply circuit 20 is in a closed state, attention is called by the display 32.</p> |
