Reply to "Garage door shut off"

Hi Does200
Inquiring minds want to know when the door is down what state is the switch in?
Because right now you have one switch and then another switch which means one is open and one is closed. With the door up. The switch lets call it to the rear is not going to be used unless the first one fails.
My guess to the first question is the switch goes from open to closed when it hits the door.(it must pick up a relay in the unit) If it was the other way around the door would not stop until both switches were accuated.

Sorry I did not respond sooner do to work commitment in Georgia.15 hour days yuck.
