Mailbox indicator comprises transmitter inside mailbox switched on when mail touches radiating arms, connected without wires to receiver in house

摘要

The indicator consists of a transmitter (1) activated by a series of radiating arms (2) on the inside base of the mailbox. The arms are slightly curved and are moved by the weight of a single letter, even an empty envelope. The transmitter is connected without wires to a receiver in the house, e.g. using a coded signal like that used by a TV remote control, setting off a sound, vibration or light indicator, which can be in the form of a decorative object that can be moved from place to place.
