Before beginning the process of replacing the switch, try another bulb.
Before working on a lamp, disconnect it from the power source. Remove the light bulb from the socket.
Squeeze and pull the top of the lamp socket to remove it from its base. If it resists, use a screwdriver to pry it from the base. Once it is apart, use pliers to cut the wires.
The switch is located in the socket and should now be loose. Remove it, and replace it with a new switch. Reattach the wires, and reassemble the socket. Replace the light bulb, and test the lamp.
If replacing the switch does not repair the lamp, the socket is likely bad. Unplug the lamp, and remove the light bulb again. Remove the socket from its base. Loosen the set screw in the narrow part of the socket base. Turn the base to unscrew it from the lamp. Replace the old socket with a new one. Reassemble the lamp, and test again.
