The three-way pull chain socket can be used to replace a worn or broken socket or to build an entirely new light fixture. This socket pairs with a three-way bulb to offer three light levels. The pull chain switch is well suited to floor or table fixtures and its brass finish lends a classic look and effectively withstands heat. Thanks to its straight bracket design, installation is easy. The 2-1/4 inch high socket has a tapped 1/8-IP bushing and uses medium-base bulbs.
