Abstract

Un dispositivo interruptor de circuitos perfeccionado que comprende contactos cooperantes, un conjunto de brazos de contacto que comprende brazos de contacto pivotantes conductores, primero y segundo que soportan a dicho contactos, un mecanismo de maniobra conectado al segundo brazo de contacto y operable para moverlo a posiciones de contactos abiertos y cerrados con respecto al primer brazo de contacto, medios pasivos posicionadores de brazo que limitan el desplazamiento de dicho primer brazo de contacto en dirección hacia dicho segundo brazo de contacto, un conjunto activo posicionador de brazo que comprende un miembro de apoyo que hace tope contra dicho primer brazo de contacto en le lado opuesto de dicho segundo brazo de contacto y medios de carga que solicitan a dicho miembro de apoyo a ir contra dicho primer brazo de contacto en dirección hacia el segundo brazo de contacto y medios conductores conectados a dichos brazos de contacto y que hacen posible que el interruptor de circuitos sea conectado en serie con un circuito eléctrico exterior a proteger, estando dispuestos dichos medios conductores de modo que la corriente circule a través de los brazos de contacto cerrados en direcciones opuestas y gente una fuerza electrodinámica mutuamente repulsiva entre ellos.
