Abstract
En un indicador telefónico, una placa de montaje, dos núcleos fijados a dicha placa de montaje, una bobina arrollada sobre cada uno de dichos núcleos, un imán permanente conectado un extremo de los citados núcleos, una chapita señal sujeta por la citada placa de montaje, la citada señal siendo adaptada a ser retenida en una posición por el indicado imán permanente y medios necesarios para el movimiento de la citada señal desde la indicada posición a otra después de la neutralización de la citada fuerza magnética permanente por una corriente que pase a través de las bobinas dichas.In a telephone indicator, a mounting plate, two cores fixed to said mounting plate, a coil wound on each of said cores, a permanent magnet connected to one end of said cores, a signal plate held by said mounting plate , said signal being adapted to be retained in one position by said permanent magnet and necessary means for the movement of said signal from said position to another after neutralization of said permanent magnetic force by a current passing through of the said coils.
