The interface box is mounted directly behind the doorbell button in the wall on which the doorbell button is mounted. The interfaces box has an entrance aperture through which the doorbell wire enters the box, and a plastic neck on the front wall of the box through which the wire may be pulled out for making connection to the doorbell button. The plastic neck is sized for receiving the switch of a doorbell button of a standard size for protecting the electrical connection thereto.
