Abstract

PURPOSE:To obtain 2n times of control conditions, by extending the switch functions, through the combination of the sequence of closing of n-sets of switches for one power switch and switch circuit. CONSTITUTION:When a power switch PW is closed, DC voltages V and V' are produced, and V' is fed to the terminal (m) of the control circuit 10. On the other hand, the voltage V is given to the delay circuit 3 from the terminal (l) of the switch circuit, and after time T, a voltage (P) is produced and given to FFs4, 6. When n-sets of switches S1-Sn are on, the inverter 8 changes from 0 to positive potential, FFs4, 5- are triggered with the increment, and output signal is obtained at the terminals A1-An. When the power switch PW is on after the switches S1- Sn are on, an output signal is obtained at the terminals B1-Bn. Thus, with the sequence of closing of the power switch SW and n-sets of switches, the switch function is extended and 2n-sets of control condition can be obtained.
