1. THE SWITCH IS BAD 2.THE SWITCH WAS RECENTLY REPLACED AND WIRED INCORRECTLY (POSSIBLE IF THERE ARE MULTIPLE CABLES IN BOX 3.THE CABLE IS SHORTED (UNLIKELY, BUT I'VE SEEN IT) 4.YOU'RE TURNING OFF THE WRONG SWITCH-HA

How do you wire a motion security light from the box to the light?
You wire a security light like any other light. The sensor is generally part of the light and provides an "auxiliary" switch to detect movement and switch on the light, usually only after dark.The regular light switch for the security light should be left "on" at all times and labeled or enclosed to prevent being accidentally turned off. The sensor will not work, and the light will not go on, if the regular light switch it not on.Many modern units allow you to "lock" the motion sensor on by using the regular light switch to turn off the circuit and quickly turn it on again. This makes the light stay on until morning, when the photocell will turn it off and reset the lock, even without any motion detected.
What effect would occur if the intermediate switch s3 were replace by a double pole switch?
You seem to be referring about a 3 way lighting circuit. If the cross over switch is replaced with a double pole switch, depending on how the switch was wired into the circuit, the load lamp would either stay on or not light at all. A circuit in a three way configuration has two traveler legs between the two switches The intermediate switch in the circuit just switches the two traveler legs from open to close depending on the position of the other two switched. Google, three way switching, they have many diagrams to work from.
Practical application of passing electricity though a gas?
The most practical application is fluorescence. By passing electricity through a gas, you "excite" the electrons in the atom. Atoms "prefer" to stay at lower levels of energy. In order for the atom to lower its energy, it gives out light in photons. Because of this phenomenon, we can make neon signs, fluorescent light bulbs and even find the chemical make up of different objects using spectroscopy. A typical person probably has seen a neon sign at a bar and nowadays we have stopped using incandescent light bulbs and moved to the more efficient CFLs. (CFLs are about 4 times more energy efficient than light bulbs.) Mercury is the most prominent element in CFL bulbs and when excited, the atoms give off photons of light that are red, green and blue. The mixing of these colors give us white light. Mercury also gives off photons in the ultraviolet spectrum, which is invisible. The light bulb has a special coating that takes the energy of the UV photon and gives off a different photon in the visible light spectrum. This is why CFLs seem to have a blue tint to them.
What is saturation and active region in a transistor?
The output current of a transistor is controlled by the current in the 'base' input: Increasing the control current will increase the output current in a more or less linear fashion. In the saturation region, this is no longer true: The transistor is nearing the limits of how much current it can conduct, so increasing the control current further has little or no effect. When using a transistor as an amplifier, you want to stay away from the saturation region as it would distort the signal you are amplifying. When using a transistor as an on/off switch, as in digital circuits, being in the saturated region is 'on' and a normal mode of operation.
What did Thomas Edison discover about electricity?
Edison pushed hard for DC power as a main stay for power generation. Tesla was the inventor of AC generators. Edison learned, over the years, how much better AC was over DC. He admited this many years later, as being his greatest shortcoming in vision.
Why does my highbeam indicator light stay on and my headlights will not shut off without disconnecting the battery even though I replaced the dash switch on a 99 Dodge Dakota?
the problem is in your high beam switch. there is a short in it and it needs to be replaced
On a 1987 4runner you can only flash your brights they wont stay on even though the indicator light on the instrument panel says there on?
If the head light switch is in the OFF position, you can flash your brights by pulling the (left side handle) head light switch towards you. As long as you hold the handle the lights will stay on. If the light switch is in the ON position, the brights will STAY ON if the handle is pushed away from you. You can still flash the brights by pulling the handle towards you. If the high-beam (blue light on dash) indicator is illuminated, the brights are on - unless there is a malfunction in your unit.
In A140 Mercedes car you fitted a new reverse switch but reverse light stay on even in neatural?
Hi, did you ever find out why your A140 reverse light always stay on even in other gears, I have the same issue, i have checked the bulbs, replaced the reverse light switch and still have them always on..
Why would both of your brake lights stay on even though you are not hitting the brake petal?
Brake light switch stuck or out of adjustment. It is either located on the brake pedal somewhere or it may be a pressure switch located on or near the master cylinder.
Why does a light stay on after switch is turned off?
Either the switch is broken or it doesn't go to that light.
What cause the brake light to stay on?
SWITCH
My brake lights stay on even when the car is off The 3rd brake light is out. Brake light switch moves and the fuses seem fine. I have to dc the battery as pulling fuses didn't turn lights out.?
You probably have a faulty brake light switch
When pressing highlight low light comes on but does not stay on I have to hold the switch to keep it on. What am I doing wrong?
When I press my highlight the low light comes on but does not stay on and I have to hold the switch to keep it on.
Why do brake lights stay on?
Probably a brake light switch.
Why does the parking light stay on when you turn the car off?
because the lights are not controlled by the ignition switch; they are controlled by a separate light switch.
Why would the clock light stay on in my 1996 Beretta even after the car switch is off?
It should be on a delay and shut off after 10-20 minutes.
Why does the brake lights constantly stay on for a Nissan Pulsar lx?
It is because the brake light switch under the brake pedal is faulty. usually replacing this will solve the problem. it is designed in such a way that when the brake pedal is depressed the switch completes a circuit and the lights come on. the fault occurs when the switch closes the circuit even though the pedal is not depressed. hope this helps.
