Abstract

Un dispositivo de control eléctrico perfeccionado que comprende una caja o envolvente y, dispuestos en ella, unos medios de contacto estacionario, un contacto móvil, una corredera dentro de la envolvente para llevar el contacto móvil a unas posiciones de apertura y de cierre de contactos respecto a dichos medios de contacto estacionario, un brazo de contacto móvil dispuesto en la corredera, siendo dicho brazo de contacto portador de dicho contacto móvil, unos medios de enganche en la corredera para retener la corredera en una de las citadas posiciones, estando la corredera solicitada por acción de resorte hacia la otra posición, unos medios de reposición manualmente accionables para mover la corredera llevándola a la posición de retenida o de enganche, una pluralidad de elementos bimetálicos que se deforman o desvían al paso de determinadas corrientes de sobrecarga, y una barra transversal dispuesta para ser activada por dichos elementos bimetálicos, al deformarse o desviarse éstos, con elfin de efectuar el desenganche de la corredera.
