ABSTRACT:
An electrical relay control circuit for a plurality of controlled devices such as electric motors in which the current for actuation of the relays is regulated so that only a predetermined and precise amount of current will be available for operation of the relay coils and that current will be sufficient for actuation of only one relay thereby restricting operation to one controlled device at any one time.
