Trying to come up with a circuit to control a door actuator using a latching relay to open or close the door using a single momentary pulse trigger switch. Each time the trigger is pressed the door will move Forward or backwards. Next pulse will interrupt the signal and stop the motor. Another pulse will reverse the actuator. The ends are stopped by limit switches which in turn will reset the direction. All forward and reverse motions are done by reversing the motor polarity.
