Abstract

Un contactor electromagnético, que comprende: un armazón superior (20) que tiene un punto de contacto fijo (22) y un raíl de guiado (25); una barra transversal (30) que comprende una porción de deslizamiento (110) que se desliza sobre el raíl de guiado (25), una porción de guiado (100) situada dentro del raíl de guiado (25), un punto de contacto móvil (32) que entra en contacto y se separa con respecto al punto de contacto fijo (22) al tiempo que se desliza a lo largo del raíl de guiado (25), y un núcleo móvil (36); y un armazón inferior (10) que comprende un núcleo fijo (12) dispuesto adyacente al núcleo móvil (36), una bobina de excitación (14) que magnetiza el núcleo fijo (12) mediante una fuerza electromotriz, y un resorte de retorno (34) que ejerce una fuerza elástica sobre la barra transversal (30), en el que la porción de deslizamiento (110) está configurada por separado de la barra transversal (30), y un material que forma la porción de deslizamiento (110) tiene un coeficiente de rozamiento contra el raíl de guiado (25) menor que el de la barra transversal (30), caracterizado por que la porción de deslizamiento (110) tiene una forma de capuchón que cubre un extremo de la porción de guiado (100), y en el que sobre la superficie de la porción de deslizamiento (110) están formados una pluralidad de orificios fijos (112) para evitar que la porción de deslizamiento (110) salga fuera de la porción de guiado (100), y a través de los orificios fijos (112) están insertados una pluralidad de salientes fijos (104).
