Abstract

"IMPROVEMENTS IN THE ELECTRICAL SWITCHING MECHANISMS SIGNALING", characterized by constituting such mechanisms by the assembly of a base body adapted for coupling in its place of sustentation, on which base body are presented mounted contacts, two of which are contiguous and they are electrically connected to each other and connected to the connection cable from the power supply; while laterally to these two contacts two others are arranged to be connected with the respective connection cables of the signaling circuits; the aforementioned base body also has a lever mounted on a powered, insulating material, able to oscillate at will, which lever has at its inner end to the base body, a cavity suitable to house inside an electrically conductive part subjected permanently to the action of an elastic means, also located inside the aforesaid cavity, and tending with its action to impel the electrically conductive part towards the outside, with the particularity that the aforementioned actuating lever has with respect to the base body, three relative positions, one central and two others, the left one and the other right, so that the electrically conductive piece of which said lever is driven due to its change of position, left-center-right, it establishes the closing of the respective signaling circuits to which the aforementioned contacts are connected as well as the opening thereof in the position Central n.
