Not sure if the door switch is another component or not, but the player built doors seemed to not have the switches. Opening the door is easy enough, but closing it seems a bit more hassle with out the switch.

Would be nice to add it on and believe should be part of the door component rather than a separate item. Settlement limit seems a little tight as it is.
