Patent ID: 7161101

Claim:
Lamp-socket with built-in switch mechanism, wherein the switch mechanism is operated by a knob, a cord, a chain or a layer associated with a ratchet mechanism to close and to open power supply connection contacts of the lamp by means of corresponding terminals, the lamp-socket having, at a back side thereof, a connection bridge perpendicularly and centrally extending behind a lamp-socket tubular front part defining a lamp receiving cavity, said bridge being defined by a pair of lateral walls having lateral edges that are next to a contour of the lamp-socket front part and respective transversal upper edges defining a back end of the bridge, wherein the switch mechanism is connected in a lateral plane of the lamp-socket connection bridge and behind the lamp-socket tubular front part, the switch mechanism being arranged within a gap defined by a perimeter of the lamp-socket front part and by the connection bridge, and wherein the switch mechanism includes a ratchet sleeve having a front side to which a lever is connected for actuating the switch mechanism, the sleeve having a back side connected to a spiral electrical bridge in operative relation with a pair of contacts defining connection paths fixed on a lateral face of the connection bridge of the lamp-socket, the paths being extended according to respective annular steps formed on a sidewall of the connection bridge.
