are you talking about electronic manufacturer or alarm manufacturer...

cause it was never the case with electronic manufacturer....

and alarm one had to cope with people like you so they went bananas about
telling witch state a contact should be named at...

in this industry normal sate is when the switch is at the ready state..so
when the door contact is close to its magnet...

much easily said then all the bs you post....
