Is it acceptable to daisy chain light fixtures on the same switch?

Answer 1

=== === The answer given below is ONLY for USA, Canada and countries using similar 120 Volt, 60 Hz mains power supply systems. The answer given below is NOT for Europe or anywhere else

using 230 Volt, 50 Hz mains power supplies. == Yes. Switch off the power at the panel then wire the light fixtures in parallel with each other but be careful not to exceed the current ratings of the switch or the breaker protecting the circuit. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work AND

always use an electrician's test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized. It is absolutely critical that you de-energize the circuit you are going to work on before you attempt anymodifications. And you must use the correct equipment and use it correctly to insure the circuit you are going to open up is de-energized. Additionally, you must insure that the fixtures you may wish to add will not load the circuit beyond standard maximums for that given leg of the power distribution system in the structure. There are limits on a circuit based on what fixtures are on it, the wire size, the length of the run(s), and the rating of the circuit breaker that combine to set limits on what can and should be run on that circuit. If the "math" behind evaluating the ratings and of what is already on a circuit and what you might wish to add are beyond your calculation, this is a clear indication that you should not be attempting any kind of modification to an electrical system. As a reminder, people are killed every year in fires that began in electrical systems where work was done incorrectly or to less than workman like standards. And the property losses are horrendous. Do not become a statistic by setting aside your common sense and good judgment. Some people can design rockets, and some can perform neurosurgery. And some can't. No fault, no foul. Resist the urge to "experiment" with any work of this type. If you're not an electrician or do not understand the principles that apply, it's not a personal shortcoming or a character flaw. Refer work to those who do have the knowledge, skill and ability to do the work you need done. If you are insistent, you can work something out with an electrical professional to do the labor installing the fixtures and leave the wiring to the pro.

Answer 2

I presume you mean control one light from two or more switching positions.

IF SO, then in wikipedia.org/multiway switching will give you a pointer.

Remember, mains currents are dangerous. Please take care to understand what you do.

Light fixtures are not daisy chained wired. Light fixtures are wired in parallel. If the fixtures were wired in series that they would act as Christmas tree lights, when one burns out, they would all go out.
