Lighted module applicable to a pushbutton-type switch assembly, and a pushbutton-type switch assembly with a lighted module

A lighted module applicable to a pushbutton-type switch assembly, where said pushbutton-type switch assembly is of the type comprising a base body defining at one end a bezel adapted to receive a pushbutton of an actuator assembly and a stem adapted to pass through an aperture of a panel, said stem having an outer configuration adapted for joining said base body to said panel, said actuator assembly being mounted so as to be moved through said stem from an extended position to a retracted position against the thrust of an elastic element to operate an actuating element of a switch attached to said stem, said lighted module comprising:

• a receptacle inside of which a printed circuit board is installed, said printed circuit board having a circuit including at least one LED and connection means, said receptacle including at least one translucent or transparent portion, aperture or hole through which light is emitted from said LED towards a translucent or transparent portion of the base body, and
• at least one orifice through which said connection means is connected to an electric circuit, the receptacle and said printed circuit board comprising respective mutually aligned apertures and for insertion of the stem of the base body, so that the receptacle with the printed circuit board is jointly installed with the pushbutton-type switch assembly either internally or externally to the panel,
• wherein said circuit of the printed circuit board includes a number of LEDs distributed around said aperture on a first face of the printed circuit board, while said connection means comprises connection pins extending from a second face of the printed circuit board opposite said first face, and the receptacle comprises a box with a bottom wall to which the printed circuit board is attached and lateral walls adapted to conform at least part to the contour of the printed circuit board, said aperture of the receptacle being formed in said bottom wall.
