A solid state control system for controlling activation signals to circuit breaker electro-mechanical close coils is disclosed. The system employs a novel arrangement of a silicon controlled rectifier (SCR) and other electronic components, such as a FET, to provide "anti-pump." The system locks out continuous close signals until after the close signal has been removed and then reapplied.
