A disconnector on Wikipedia (441-14-05) is a kind of power=switch capable to open circuits when a negligible current have to be broken. It provides a sufficient protection to high voltages when open but mustn't be operated when the power circuit is loaded.
Such a disconnector can often be found in power=substations due to its needs of an off loaded circuit to be operated.
