There is also this bar shown in the photo near the end of the door travel track that I was thinking may be some electrical shut off on the other end of that bar as the metal door traveler hits it. So as the wife set the door in motion with the garage door switch, I hit this bar hard with a hammer to see if it would stop the door moving, but no, the door kept moving. This metal bar does slide in and out though on the tack, and as shown is sitting in the end position. But there is nothing to attach it to when sliding it around up and down the track, as it just slides freely by hand.
That metal tab is a physical safety spacer to keep the traveler from crushing the light box. If the traveler overruns the switch, it will just stop and the motor will turn against the clutch until it times out or reverses.
You could use that as a foundation for a safety device of your own. Cut a length of wood, such as a 2x2 or similar, long enough to brace against the metal tab and stop the traveler from going too far. Zip tie it to the track to keep it in place. If the traveler goes too far, it will impact the wood and either trip the reverser, or stop and let the motor turn against the clutch.
All these are great ideas, like the extra switch idea and this wood spacer/stopper idea. But wouldn't the force of the traveler wreck something if it hits some mechanical stop? I figure to lift the door there is some pretty strong force doing that and the traveler too.
I see some mention an upper force and a downward force adjustment too, but I don't see anything to adjust. Is that some force adjustment on the motor area to adjust in case the door hits something? My remote and wall switch don't have any adjustments.
