Abstract
PURPOSE: To obtain the effect equal to the case with separate load unit with common power supply switch, by turing on and off the power supply of the first and second load unit when the control set is not operative and one load unit when this set is operative.
CONSTITUTION: The first and second load units 2 and 3 have one common power switch 1 and the relays 4 and 5 controlling the turning on and off of the power supply of the units 2 and 3, and the control unit controlling the current flowing to the relays 4 and 5 switchingly with transistor Tr6 and 7 is provided. That is, when this control set is inoperative, the power supply of the units 2 and 3 is simultaneously turned on and off with the operation of the switch 1. Further, when the control set is operative, the power supply of one load unit at least is turned on and off with the operation of the power switch. Thus, the power switch in common use with the units 2 and 3 can show the equal effect as separate power switch to each load unit.
