PURPOSE: To make it easy to handle by providing a selector switch on the landing side of a specific floor and connecting it in series with a car call button circuit of a specific floor in a car so as to save labor to operate the selector switch in the car. CONSTITUTION: When a selector switch A is set at override position, a specific floor cannot be served because, even if a car call button for a specific floor is pressed, the switch becomes ineffective, the specific floor cannot be served. When the selector switch A is set at operation position, the specific floor can be served because the car call button for the specific floor becomes effective. By this, the floor operation in a car can be switched over on the landing side. Thus, because the floor operation in the car and landing call can be switched over simultaneously on the landing side, it becomes unnecessary to switch over the override of the landing call button for the specific floor in the car while riding on the car. Also, because the service on the floor is difficult to produce in sleeping time, easiness in sleeping is not disturbed. |
