Abstract

PURPOSE:To make it possible to transmit an emergency signal to the 3rd person other than a talk party simultaneously with an emergency call by sticking a permanent magnet to the dial to an emergency telephone set and by providing a reed switch near the dial. CONSTITUTION:At any position on dial 2 of the emergency telephone set, small piece 3 of a permanent magnet is stuck and at the position of the immovable part to which the magnetic force extends, the read switch circuit composed of reed switch 4 and signal lines 5 and 5', and terminals 6 and 6' connected to the switch is provided corresponding to the magnet. When an informers turns dial 2 with the hole of ''119'' (for fire station), for example, in order to send emergency information, permanent magnet 3 on dial 2 moves away from the corresponding position of reed switch 4 to cut off the magnetic force of the reed switch temporarily, and consequently the reed switch at the corresponding position is closed or opened, either flowing electric current to the reed switch circuit or cutting off electric current flowing. Through this switching, an emergency signal is sent out.
