Abstract

PURPOSE:To reduce a control line between both main and subcontrol devices to half, by giving a difference to the voltage of a control signal which is used for the main and subcontrol devices. CONSTITUTION:A subcontrol device B1 is coupled with a main control device A1 with one control line J so that the output voltage Vb of a switch element driving transistor TrT4 of the subcontrol device B1 is inputted to a switch TrTi by having relation of Va<Vb to output voltage Va of an FF circuit F, and relation of Vb> Vt>Va to start voltage of the switch TrTi. For instance, in case when an operation switch Sa of the main control device A1 has been pushed, an output of the FF circuit becomes H, other Trs T2-T4 except a switch TrT1 are turned on, and a switch element G of an instrument unit C1 to be controlled is turned on. The voltage Va of a connecting point N in this case is in the condition of Va<Vt, therefore, the switch TrT1 is not turned on, and such a malfunction as the second pulse enters the FF circuit F and returns to the origin is not caused.
