Abstract

Un dispositivo electromagnético de señal que comprenda un electroimán, un circuito de excitación para dicho imán, una armadura que se desplaza entre una posición normal y otra atraída, medios para hacer funcionar la señal en una de las indicadas posiciones de la armadura, medios magnéticamente susceptibles fijos a a citada armadura, y un imán permanente colocado de forma que coopere magnéticamente con los medios susceptibles indicados en una de las indicadas posiciones de la armadura.An electromagnetic signal device comprising an electromagnet, an excitation circuit for said magnet, an armature that moves between a normal position and another attracted, means to operate the signal in one of the indicated positions of the armature, magnetically susceptible means fixed to said armature, and a permanent magnet positioned so that it cooperates magnetically with the susceptible means indicated in one of the indicated positions of the armature.
