Abstract

Perfeccionamientos en interruptores de cierre y apertura manuales y de disparo térmico, que comprenden en una carcasa un órgano de accionamiento unido a un brazo de accionamiento que es móvil alrededor de un primer pivote fijo y cuya extremidad se une por una primera articulación a una primera extremidad de una biela para constituir una palanca acodada, uniéndose una segunda extremidad de la biela por una segunda articulación a una palanca de armado, cuya primera extremidad se apoya sobre un cerrojo desplazado rotativamente alrededor de un segundo pivote fijo, por el movimiento de las láminas bimetálicas de sobre intensidad, y cuya segunda extremidad coopera con una palanca de transmisión que se asocia a los contactos móviles, y que pivota alrededor de un tercer pivote, caracterizados porque el primer pivote y el segundo pivote están colocados cerca de la parte superior de la carcasa adyacente al órgano de accionamiento, mientras que el tercer pivote que es fijo está colocado en la parte inferior, porque los tres pivotes están sensiblemente colocados en los vértices de un triángulo rectángulo, y porque los segundos y tercer pivotes están colocados en una recta sensiblemente paralela a la dirección de desplazamiento del órgano de accionamiento y a la dirección de movimiento de los contactos móviles.
