A switch control system of the present invention comprises a plurality of channels each comprising an individual input terminal and a flip-flop, and a clock pulse generator for generating clocks in response to an individual selection signal applied to any one of the channels. The said individual selection signal is written and stored in the flip-flop of the corresponding channel as a function of the clocks for bringing the channel in an active state. A switch control system of a preferred embodiment is also capable of being controlled with a common selection signal applied to a common input terminal as well as the individual selection signals to be applied individually to the respective individual input terminals by means of a ring counter connection formed between the respective flip-flops. In accordance with another embodiment a chain of pulses is applied in a remote control manner to the common input terminal and the first portion of the chain pulses is used to forcibly return the system in an initial condition in which a predetermined flip-flop is in an active state, while the remaining portion of the chain pulses is used to shift the active state in the flip-flops connected in a ring counter manner depending upon the number of chain pulses as determined by manual individual selection. |
