The photo to the left is of an intercome system type thingy......like my definition?? These are found in most German homes. When someone rings your doorbell, you can pick up this phone and talk to them. And if it works right, you can push a button and the front door will make a buzz sound which lets the person know you have unlocked the door so they may come in. Usually the door will stay locked. After they come in and shut the door, it will lock again on its own. Of course, mine does not work. The door is either locked or unlocked.
The photo to the right is of a lightswitch. Hmmm....interesting :)
Usually the ones for the bathrooms are outside of the room next to the door. Other rooms, the switch is usually located in the room.
