It is made up of four quick connection keys -2-, two by two, on sides of the base -1- in a V shape, lateral cylindrical pins -17- being situated on semicylindrical seats -18- that the base -1- has in the sides of respective location housings -3- of each key -2-, swinging there from the horizontal position prior to placement until the initial vertical position of the electrical wire -19-connection, said key -2- being in this vertical position, until the bottom of the cylindrical hollow -20-, situated on its external face -21-. This key -2- is forkshaped at its internal face -2-, forming an upper aperture -23-, wherein is situated the front face of the corresponding knife contact -4- and -4a-, whose face is equipped with an aperture -4b-, which upon initiating the displacement of the key -2- towards inside the base, penetrates inside the aperture -23-cutting through both sides of the insulation of the wire -19- of the aperture - 4b-, making contact with its core, and trapping it. In its initial stable position, the key -2- has two buffers, next to its edge, wherefrom a stub -24- is located inside a slot -25- of the base -1- and one stub -26- outside of the edge thereof. It also has another stub -27-, rested on a spring -28- of the base -1-, situated below the lower face of its lateral walls and is positioned, finally, behind said spring -28- by clipping. The base -1- has four teeth -13-, two by two, to situate the contacts -4- and -4a-, fitted into internal slots -14- of the cover -12-, base and cover remaining held shut and the mechanism closed. According to the switch and push button, it only needs requires three knife contacts, a moving contact -8-, which in its "non contact" position rests on a buffer -29- of the base -1-, comes into contact with the third -4a-. It has a light emitting device -30-, above the swinging element -11- equipped with contacts -31- which penetrate through apertures -16a- in the cover -12-. |
