Control circuit for a motor-operated switch

A motor control circuit for controlling operation of a motor for making or breaking one or more pairs of contacts of a power switching device such as a circuit breaker, said motor control circuit comprising:

• a logic circuit responsive to "on" and "off" control input signals and an enable signal for producing an active logic signal state when one of said control signals and said enable signal both are present, and for producing an inactive logic signal state either when neither one of said control signals is present or when said enable signal is not present;
• and
• a switching control signal producing circuit responsive to said active state of said logic signal for producing a switching control signal for operating said motor for a predetermined time interval sufficient to perform one of opening and closing of said one or more pairs of contacts.
