Abstract: A motor control circuit for preventing automatic restarting of an electric motor following an interruption of electric current flow therethrough. An electric motor incorporates winding means and a series automatic reset thermal overload protector. Current flow to the motor is normally controlled by current supply switch means in series with the motor across electric power input terminals. A first relay device is switched by external actuation of a normally open start switch to switch the current supply switch means to its conductive state for starting the motor. A second relay device connected across a pair of motor terminals is energizable in response to current flow through the motor. A restart prevention switch connects in series with the current supply switch and motor across the electric power terminals.
