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.
[Similar to a spark coil in an automobile (pre electronic ignition)]
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.
surface type switches is a switches in the wall while flush type switches is connected in the outlet of appliances. this is the best answer for that!
dip switches are like wall switches. the term dip is dual inline package. that refers to how they look like microchips with lever thingies on them.
one power source two diffrent switches

A 3 way wall switch is used in a circuit for two switches that can turn a light fixture on or off from two different locations. Both switches must be 3 way switches. For more information see the answers to the Related Questions shown below.
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.
Yes, if they replace the switch at the wall.
