The device that holds a light bulb is called a keyed lampholder or a pull chain lampholder. These have the switch built into the base of the holder and have switch that looks like a key or a pull chain to operate the switch. Wire the continuous "hot' wire to the brass screw on the lamp holder (the other side of the switch is attached to the light socket at the factory). The neutral white wire will go onto the silver screw terminal. See related link below for some examples. There also pull-chain and other "canopy" switches that you could, in theory, install in an existing light fixture. However, it would almost certainly violate any UL or other safety listing on that fixture, perhaps causing problems with your inspector or insurance.
You have both a mechanical and electrical issue. From a mechanical standpoint you need the switch mounted securely in the fixture. The switch will have two black wires or two terminals. You need to insert the switch in series with the black wire going to the fixture. Let's say that the black wire from a supply is connected to the black wire in the fixture with a wirenut. Undo the two wires and connect each wire to a wire on the switch.
The most likely cause is a fault in the switch. Replace the switch and the problem will most likely disappear.
To install a new fixture to replace the one that was removed reconnect the two hot wires together and then reconnect the two neutral wires together. Place the two wires from the new fixture to the corresponding wire colours that you just spliced together. This wiring should be down stream from the light switch. When the switch is turned on the new fixture should light. If this is not the scenario of your question then more information needs to be given.

It just holds the bulb, does not have a switch in the fixture.
No, a switch is used to control the circuit voltage that is applied to the fixture for turning the fixture on and off. The starter in the fluorescent fixture is used to start the current flowing through the filaments in the fixture's tubes. After a specific time, the starter heats up the circuit is opened and the current then flows through the fluorescent tubes.
A three way switch can be used as a single switch. Replacing this switch will not allow you to switch a fixture from two locations unless there is a three wire cable going to the second box.
The light is wired the same as any voltage fixture. Bring the source voltage to the fixture and connect it to the two fixture wires. If you want to control the off-on of the fixture take the source voltage to a switch first and then out of the switch to the light fixture.
If the question is, can I wire a switch to an existing light fixture (and I must assume that it's something like a pull-chain light fixture), the answer is yes.If the question is, "how do I wire a switch to an existing light fixture that has no external switch", the answer is, "in series".The attached web site gives simple instructions on how to wire a basic light switch to an existing light.See sources and related links below
