1. A snap hinge with damped closure, comprising: a first articulated quadrilateral and a second articulated quadrilateral each defined by pivot points and which share a first lever and a second lever; a coupling plate connected to a first element and the first articulated quadrilateral; a fixing plate connected to a second element and the second articulated quadrilateral, the hinge being movable alternately between an open configuration and a closed configuration, wherein the plates have different arrangements with respect to each other, at least one damping element that is interposed between the second quadrilateral and the fixing plate or between the first quadrilateral and the coupling plate for damped transition from the open configuration to the closed configuration or vice versa, wherein the second articulated quadrilateral comprises a first arm that is articulated to the fixing plate and to an end of the first lever, the at least one damping element being interposed between the fixing plate and the first arm, wherein the at least one damping element comprises a main body in which a stem is slidable axially, the main body having a first end rotatable with the fixing plate and the stem having a second end movable with respect to the first end and is rotatable with the first arm, the at least one damping element movable alternately between a compression position, in which the first and second ends are mutually closer and the hinge is in the open configuration, and an extension position, in which the first and second ends are mutually spaced and the hinge is in the closed configuration, wherein the first arm comprises a first pivot point that is hinged to the fixing plate, a second pivot point that is hinged to one end of the first lever and a first fulcrum that is hinged to the second end, the first pivot and the second pivot delimiting one side of the second quadrilateral and the first fulcrum being arranged outside the second quadrilateral.
