Abstract

PURPOSE:To secure the 3-way switch function and thus to faciliate both alteration of the wiring and increment of the terminals by inverting the control signals to the terminal only when the state is changed for the control switch provided to the terminal. CONSTITUTION:The 1st address signal and the 2nd address signal corresponding to terminal B are transmitted from address signal writing circuit WRITE via timing signal generation circuit TIMING. At output signal generation circuit OUTGOING, an adjustment is given properly to the control signals given from instantaneous reading memory unit RAM4 and acompanying the same signal as the 2nd address signal, and the control signal is then transmitted to terminal B via input/output circuit CONTACT. On the other hand, only when the 1st and 2nd reception signals corresponding to the states of current and preceding control switches and to be supplied to exclusive negative logic sum circuit group MORELSE differ from each other, the signal produced by inverting the output of RAM5 is generated via NORELSE.
