Spring Contacts for Doors

Simple energy transfer from the door frame into the door itself. Door contacts are embedded in both the frame and the door. Upon closing the door, the spring contacts connect, and create an electrical circuit with the lock or the magnet. The areas of door contacts are large enough to enable a reliable energy transfer even in case of the door being moved within the frame or in case of imprecise assembly. Window security. The security loop is broken with the window being opened. State of danger.
