The utility model discloses a simple and easy indicator board of loop service for cubical switchboard, including the pulse signal device, the output passing signal line electricity of pulse signal device be connected with can side of centre gripping mutual -inductor the signal press from both sides, still including pressing from both sides with the output of mutual -inductor secondary side terminal centre gripping complex, two outputs are pressed from both sides has a charging capacitor through the output line is parallelly connected, the charging capacitor is anodal to have concatenated unidirectional diode with corresponding between the output line, anodal and the microcontroller type of charging capacitor hold electric the connection, singlechip output electricity is connected with the alarm. The advantage effect is: it is rational in infrastructure, can directly perceivedly display the loop service condition, simple to operate dismantles fast, and status switching is simple in the power supply, can effectively avoid the logical electric phenomena's of live working or operation mistiming emergence, helps improving the operation security.
