摘要
PURPOSE: A normal state and a reverse state indication lamp are provided to prevent the malfunction of a signal by driving a indication lamp by being controlled to a current state of an indication relay. CONSTITUTION: A normal state indication lamp(200) is assembled in a protection case, is installed in a branch point of a railway line, and is driven in the normal state. A reverse state indication lamp(300) is assembled in the protection case, is installed in the branch point, and is driven in the reverse state. A current switch(201,301) opens and closes the driving current of the reverse state indication lamp and the normal state indication lamp. A drive current supplier(150) supplies a driving current to the normal and reverse state indication lamp through the driving current switch. The protection case protects the normal and the reverse state indication lamp from the wind and rain and the thunderstroke.
