Abstract
The invention discloses a delivery signal device for a mailbox. It comprises a catcher means (11) connected to the effort arm of a lever (15) which operates a magnetic switch (14). The magnetic switch (14) operates an electrical circuit (19) which then activates a warning system. In one embodiment as taught by the invention, the warning system employs a flashing LED light (30) and this is achieved with the assistance of an integrated electrical circuit (19). The size of the catcher means (11) can be flexibly designed to fit that of a mailbox. To provide equilibrium to the lever (15), a counter weight (13) is provided on the load arm of the lever (15) opposite the catcher means (11). The underside of the load arm of the lever (15) is further provided with a magnet means (14a) operating a normally closed reed switch (14b).
