Abstract
Perfeccionamientos en los interruptores al vacío, del tipo que comprende una envoltura en la que se ha practicado el vacío y que tiene en su interior dos elementos de contacto fijos que tienen un espacio eléctricamente aislante entre ellos, y una bobina electromagnética que funciona para producir un campo magnético en la zona del espacio entre los elementos de contacto, estando el campo magnético substancialmente de modo paralelo con respecto a la anchura del espacio, caracterizado porque los terminales de la bobina están conectados respectivamente a dos discos eléctricamente aislante, estando montado un conjunto que comprende el disco aislante y los dos discos metálicos en cada lado del mismo dentro del espacio entre los dos elementos de contacto fijos, estando puenteados los elementos de contacto en el estado cerrado del interruptor por un tercer elemento de contacto móvil con forma de U del interruptor.
