Keyless Nickel lamp sockets have a nickel plated shell and cap with set screw. Standard nickel lamp sockets are tapped to fit standard lamp pipe. Use keyless nickel lamp sockets with a cord switch or wall switch to turn on or off. Keyless lamp sockets can be used on wall sconces, chandeliers or lamps.
Before making any changes to electrical fixtures and lamps:
Disconnect plug/wire from the electrical source.
Turning lamp off will not protect you from electric shock.
If you are unsure how to safely proceed contact a licensed electrician.
