Abstract

Aparato telefónico mejorado, caracterizado por el hecho de constar de dos campos magnéticos que ejercen acción simple o complementaria sobre un interruptor de ampolla, de tal manera que uno de los imanes está vinculado a la base o soporte a distancia prefijada del interruptor de ampolla para que no interferirse ningún otro campo campo magnético su acción sea suficiente para cerrar los circuitos y permitir la conversación, pero que al acercarle a una distancia crítica y prefijada de antemano, otro campo magnético materializado por un imán dispuesto en el microauricular del aparato, el campo de este segundo imán anula el campo del primero y dominándolo, actúa, sobre los terminales del interruptor de ampolla abriendo los circuitos y desactivando la corriente.
