Abstract

PURPOSE: To rise the utilization efficiency of display board by permitting the mounting of a display plate with a magnet onto the surface of display board by embedding a magnetic substance into non-magnetic display board and also by providing a switch responsible through the magnetic substance to the back side of the display board.
CONSTITUTION: The surface of the system display board 1 is formed of the non- magnetic plate 30 the inside of which is buried with the magnetic substances 31 and 32 to form magnetic path and the back side of which is provided with the lead switch 33 through the magnetic substances 31 and 32. Accordingly, when the display plate 20 with the magnet 21 is attached to the display board 1, a magnetic path is formed through the magnetic substances 31 and 32 and thereby the contacts 33 and 34 become ON, permitting the taking-out of electric signal to the outside. Thus, it is possible to raise the utilization efficiency of the display board by using the output signal of the lead switch 33 as the operational interlock condition of apparatus when making display during earthing.
