Abstract

"IMPROVEMENTS IN THE ELECTRICAL MECHANISMS SIGNALING SWITCHES", characterized by providing the base body with such mechanisms, with insulating plates acting as a platform, one of which has assembled a series of assemblies in the form of terminals constituted by electrically conductive pieces, to be connected three of them with the respective connection cables of certain circuits of the mechanism, while another is connected to the circuit cable corresponding to a secondary power source, whose parts are provided with flexible sheets, also electrically conductive, fixed opportunely to the respective pieces, while in its opposite part to that of its fixing such sheets are provided with a contact, with the particularity that said flexible sheets are arranged around a metal piece connected to a cable of the circuit corresponding to the main power source whose metal piece ca is integral to the insulating plate in question presenting itself for this metal piece, located in a seat cavity that for this purpose has said plate, whose metal piece has determined on its surface a series of embossments that give rise to the body of the same to a path susceptible of being traversed by the internal end to such a base body of a driven lever articulated to said base body, so that said path determines that said lever can only adopt, with respect to the repeated base body, three positions relative to one central and two others, the one left and the other right, so that the aforementioned internal end of said lever that is electrically conductive, due to its change of left-center-right position, establishes the closure of the circuits to which correspond two of the aforementioned pieces of high electrical conductivity carriers of the flexible sheets, as well as the opening thereof in the to the central position, with the particularity that part of the aforementioned actuating lever, when operated in a predetermined direction, is capable of being retracted at will relative to the rest of such lever, so that the part in question in its retraction it establishes the electrical contact between the electrically conductive part connected to the secondary power source mentioned above and the third part of those connected to said circuits, whose contact between both parts is established through their respective flexible sheets.
