Universal integrated device for controlling gas-burner rings of a cooking surface including a gas tap and a catenary element

A bushing configured to be installed on a device for controlling the gas-burner rings of a cooking surface, said device comprising:

• a gas tap equipped with a control knob;
• a catenary element operable to ignite the gas-burner rings, the catenary element comprising a microswitch selectively actuated by a contrast element carried axially by a mobile element of the gas tap, wherein said contrast element comprises said bushing fittable directly, via snap action, on said mobile element of the gas tap, the bushing comprising:
• a mounting sleeve configured to mount said bushing on said mobile element, and
• a circular flange, any angular portion of said flange being configured to bear upon said microswitch to actuate said microswitch as a result of an axial motion of the mobile element;
• a radially internal annular detent and a radial slit that interrupts the continuity of the flange;
• and
• a pair of radially opposed internal circumferential slots disposed in an angular position corresponding to an angular position of the slit that interrupt the continuity of the detent;
• wherein said mobile element further comprises an annular seat disposed on an external side surface of the mobile element and the detent is configured to lockingly engage the annular seat.
