Abstract
Dispositvo perfeccionado de disparo para relés térmicos, que incorporando una horquilla de accionamiento basculante mandada por un empujador que actúa sobre un resorte de tracción que conecta un punto medio de la horquilla a un punto fijo de la carcasa del dispositivo; caracterizado esencialmente porque la horquilla por su extremo libre basculante conecta, con capacidad de articulación con una barra deslizante portacontactos que está guiada longitudinal y transversalmente en cuya barra se han previsto contactos de trabajo de doble ruptura que están continuamente presionados por un resorte que por su extremo libre se apoya en un piso fijo respecto a la barra, de modo que la presión que ejerce sobre los contactos es independiente de la presión que ejerce sobre la barra en su posición operante o de armado de contacto habiéndose previsto un contacto de reposo, también de doble ruptura que es independiente del contacto de trabajo y actúa inversamente a él.
