Abstract

Switch, characterized by comprising a body, electrical contacts with open and close position, a driven element movable with respect to the body to pass the contacts from the open to the closed position, elastic means able to exert a force on the driven element which closes the contacts and an intermediate element intended to support at least a part of said force so that, while the intermediate element is in service the elastic members can not close the contacts. Said intermediate element is capable of being deformed under the manual application of pressure on the surface of the switch, the pressure acting in the direction in which the intermediate element would move under the action of the elastic means, so that, once deformed, said element intermediate is no longer able to withstand the force, nor part of it, and allows the elastic means to close the contacts remaining deformed after ceasing to apply pressure.
