Abstract
The present invention is a safety feature in an automatic garage door operator. In the prior art a single momentary contact push button, either directly connected to the automatic garage door operator or connected via a radio transmitter, is used to control door operation. In accordance with the present invention, closing the garage door requires continuous actuation of the momentary contact push button from the time the operation is begun until the door is fully closed. Any interruption in this continuous operation causes the automatic garage door operator to reverse and fully open the door. Thus continuous attention of the operator is required, thus enhancing safety because of the attention of the operator.
