Pull chain light fixture, in many homes, especially older ones; the overhead lamps installed are often controlled by a switch pull chain. A simple switch can in a way which simply turns on or off, or it could be a three-way model. Both are relatively inexpensive and also easy to install. If the pull chain switch is giving you problems, there are several likely causes.
Related to pull chain light fixture, the first is three-way switch. If your option is a three-way model, it is designed to control a three-way bulb. These lamps contain two separate strands that want to illuminate individually or together to create the three levels of light. So your problem can not be the key at all. Replace the existing lamp and the switch gradually turns into all three light settings, the old bulb was the culprit. If the lamp lights, but soon begins to flash, the problem could probably be a wire nut loose inside the fixture housing or under the roof canopy. Turn off the power at the circuit breaker panel or fuse box and inspect the wire nuts for a comfortable fit. If someone has already started working itself loose, tighten it or replace it. Restore power and test the results. If the flicker disappears, you have successfully addressed the problem. If oscillation continues, the next likely suspect is the light socket. The contact can be used. Purchase and install a replacement. If the oscillation stops, you took care of the situation. If all these actions do not correct the problem, the solution is left is to replace the switch. Replacements can be purchased at home improvement centers or hardware stores. If you must replace the pull chain switch, always choose one that received a “UL” (Underwriters Laboratories) certification.
Then the second is a position of the switch. If your machine is equipped with a switch of a conventional two-wire position, check the bulb, wire nut and light socket. If the switch becomes the problem, you can fix the equipment and update the device with the installation of a three-way switch. Both units are similar in size and will have the same amount of time to install. How do you isolate the problem with your unit current draw if the problems above happen? The solution is just read explanation above. Finally, that’s all about pull chain light fixture that can I share this time thank you very much.
