Abstract: An electrical operator assembly for garage doors and the like includes a reversible electric motor, a belt member and means deflecting the belt member from a straight line path. When the door operated by the assembly encounters an obstruction, the belt member overcomes the deflecting pressure and operates reversing switch means to reverse the direction of operation of the electric motor. The control circuitry includes a multiposition relay adapted to reverse the direction of operation of the motor upon change of the contacts closed therein when a signal is received from the reversing switch which transmits its signal directly to the relay. In addition, a disabling switch is directly responsive to operation of the drive means after a preselected period of travel in one direction to disable the reversing switch and prevent its transmission of a signal to the motor when the door approaches the end of its preselected period of travel in that direction. The motor remains in closed circuit contact with the relay means during reversal of direction by the reversing switch.
