CFL's have tiny switching powersupplies in the base of the la(m)p to drive the tube. The first thing the switcher does is rectify the line to DC to power the rest of the circuit. Because the manufacturer is trying to cram a lot into a tiny lamp base, they sometimes leave out precharge and power factor correction circuits. Because of this cheap CFLs have the line feeding a bridge rectifier into a capacitor bank directy. This means that when the capacitors are empty, they will look like a short to the line until they charge (I = c dv/dt c is constant, dv/dt is a function of line voltage and the charge on the capacitor). This instant of high current draw is the same instant the contacts on the switch are closing, causing the spark.

Inductance of Circuit can cause spark aswell.
In the CFL Circuit, is also an Auto-transformer of sorts, to transform the High Frequency, AC into a High Voltage to cause the tube to reach strike voltage, and then maintain a limit on the current, becasue as the ions in the tube collide and react with each other, they release electrons. As those electrons are converted into photons by the reaction, there is the replenishment of the electrons by the source ac current.
When an Inductor, has its current, the magnetic field wants to keep on going, but now, across the contacts is a high resistance, and the instantaneous impedance is several megohms, but with the trailing current of the tube still running, a slight charge is available to reflect back into the circuit.

This causes a high-voltage to be impressed across the two contacts of the switch, and causes the contacts to pit, as the high voltage is dissipated into the pole (or ground mount) transformer secondary windings.
This can cause harmonics to be reflected back into the primary but the duration is very short. One or two cycles (16.6 - 33.2 mSec) or less.
Yes, if they replace the switch at the wall.
Say the wire attached to a wall plug is not screwed tightly onto the terminal. If you plug something like a heater into that outlet, the current flow across that loose terminal will get it warm and as time goes on even hot, even hot enough to start the wall on fire.
Yes, it is possible to punch a hole in a wall, especially if the wall is made of drywall or plaster. However, punching a hole in a wall can cause damage and may require repair. It is not recommended to intentionally punch a hole in a wall.
A pull-string or pull-chain switch IS a light switch. Some other types of light switches are called wall switches and cord switches.For more information see the answers to the Related questions shown below.
If "your wall" is in North America then the answer is 60 Hertz (Hz) or 60 cycles per second in the form of a sine wave.
The different types of fan wall switches available in the market include single-pole switches, dual-pole switches, variable speed switches, and remote control switches.
The different types of wall light switches available for home lighting control include toggle switches, rocker switches, dimmer switches, and smart switches.
The different types of electrical wall switches available for home use include toggle switches, rocker switches, dimmer switches, and smart switches. Each type offers unique features and functions to control the lighting and electrical devices in a home.
There are three main types of fan light control switches available in the market: pull chain switches, remote control switches, and wall-mounted switches. Pull chain switches are operated by manually pulling a chain to adjust the fan speed and light settings. Remote control switches allow for wireless operation of the fan and light settings from a distance. Wall-mounted switches are installed on the wall and provide a convenient way to control the fan and light settings with the push of a button.
The different options available for controlling a ceiling fan using wall controls include basic on/off switches, speed control switches, and switches with remote control capabilities.
How did you want to switch on the bulbs? If there isn't a separate circuit already running from the switch, through the wall, and to the chandelier, then you'd have buy pull chain switches. The chandelier would have to have holes drilled to mount the switches. The load wire from the house would be wired to the load side of each switch. Then two bulbs to one switch and three bulbs to the other switch. All the neutrals would tie together to the neutral from the house. I would HIGHLY recommend just purchasing a dimmer switch from your local hardware or home center. You could easily change the switch in the wall to a dimmer switch and have a lot more control over the illumination, and it wouldn't look like you have burned out light bulbs in your fixture. You can rewire a 5-bulb light for a 3-2 switch in a couple of other ways. Remove the light from the ceiling, open the lamp wiring and divide the selected 3 and 3-light sets. All of the neutral wires stay together (usually wired to the screw shell of the lamp holders). Add a 3-way switch in the fixture (e.g., off, 3-on, 5-on, or off, 2-on, 5-on) or bring each group of 3 and 2 hot wires out to separate wall switches. Switch 1 is 2 bulbs, switch 2 is the other 3 bulbs, and switch 1 and 2 together is all 5 bulbs. Or you can put all or some of them on dimmers.
An electrical supply store carries items such as light bulbs, extension cords, wall switches, fans, wiring supplies, as well as light fixtures. One could also find various tools as well.
Harbor Breeze fans offer a variety of switch options, including pull chain switches, remote control switches, and wall-mounted switches. These switches allow users to control the fan's speed, direction, and lighting features.
Fluorescent light bulbs have an inner wall coated with phosphor powder. This coating converts the ultraviolet light produced by the bulb into visible light when it strikes the phosphor.
A unit with several small rocker-type switches that plugs into a dual in-line package (DIP) on a printed circuit board.
Flush type switches have buttons that are flush with the surface of the switch housing, while surface type switches have buttons that protrude from the housing. Flush type switches are preferred for clean and modern aesthetics, while surface type switches offer better tactile feedback and are easier to locate by touch.
Yes, if they replace the switch at the wall.
