ABSTRACT:
Control system including radio receiver circuit for a power-driven operator for garage doors and the like comprising an operator control circuit having a regulated DC voltage source operating as a power supply for an electronic flip-flop device responsive to successively applied input signals to establish circuits of opposite direction through a reversible electric motor; i.e., one actuation causes the motor to run in one direction and the next actuation causes it to run in the opposite direction. The operator is subject to actuation by both a hard-wired push-button and a radio receiver which is responsive to signals from a remote transmitter. The power supply for the flip-flop is also the power supply for the receiver; however, the receiver is packaged separately from the operator and power supply and is readily disconnected for independent maintenance and repair.
