ABSTRACT:
Lamp-socket with built-in switch, wherein the switch can to be driven by a knob, a cord, a chain or a lever associated with a type “ratchet” mechanism which allows to close and to open the lamp power supply connection contacts. On transversal plane defined in the back end of its frontal side, the lamp-socket has a perpendicular connection bridge where the switching mechanism is laterally engaged, this is confined according with the projection of the gap defined by the lamp-socket frontal side perimeter and by the height of the bridge upper transversal edge. The switching mechanism, according to the possible embodiments, is conformed by a “ratchet sleeve” associated with a cam or “lever creek” in order to actuate it by a cord or a chain, or by a revolving bushing actuated by a knob or a “L” shaped lever. The switching mechanism is generally small shaped and, as a result of being laterally engaged on the connection bridge, it occupies a space so as it allows the lamp-socket to be substantially as height and to have a diameter as any conventional lamp-socket.
