LOAD FACILITY SETTING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a load facility setting device that assures easier manufacture and reduction in cost. SOLUTION: A used device on/off selecting circuit 22 and a circuit 23 for setting the number of units to be used most frequently are connected to a power supply circuit 21. To the power supply circuit 21, a step on-signal generating circuit 26 and a step off-signal generating circuit 27 are connected and an excessive on-operation invalidate a control relay circuit 28 is also connected to the generating circuit 27. The structure can be simplified by alternately incorporating the relays to this relay circuit 28.
