Abstract

PURPOSE:To enable the center to grasp the status of terminals, by adopting the switch circuit which can not be returned for several seconds after switching. CONSTITUTION:When the power supply of terminal units are OFF, the switch 2 is not turned to OFF direcrion. When the switch 2 is rotated to turn on, the interlock switch 11 by a relay is closed to finish the power supply application operation. The application of power supply is informed to the center and when the answer returns, the depression of the transmission request key on the keyboard is made effective to turn on the switch 3. Thus, the rotation toward ON is suppressed for the switch 3 and the switch can be turned to OFF direction only. After this period, even when the switch 2 is turned to OFF, since the switch 10 is ON, the power supply is not disconnected and the switch 2 can not be turned to ON direction.
