The purpose of a switch is to stop and start a current flow in a circuit. The stopping of a current flow in a circuit effects the load of the circuit by stopping its action. Resuming the current flow in a circuit also resumes the action of the load.
That depends on your meaning. Are you talking about turning off the breaker when you screw in a new lightbulb or fluorescent tube? That isn't necessary, but it is a good idea to turn off the switch. If you're talking about installing a new light fixture, yes, you should always turn off the breaker or remove the fuse. Many electricians, if they are sure of what they're doing, will simply make certain that the light switch is turned off.
Yes, you need to turn off the power when you change (replace) a light switch, since at least one of the terminals on the switch will always have power if the circuit is energized at the panel.
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.
I've seen it called "hallway wiring". The idea is the same in both cases . . . there's a switch at both ends, and either switch can turn the light on and off, regardless of the position of the other switch. That way, a single person can turn the light on at one end of the hallway or staircase, walk up the stairs or through the hallway, and turn the light off when he reaches the other end.
To control a light with a switch, the switch has to be connected in series with the light fixture.
a light switch
well most people say turn off the light but you could say switch of the light.
Yes. Simply turn on the ceiling fan while the light switch is in the "on" position. Adjust the spinning to the level of your choice. Now the fan will turn on and off when you switch the light on and off.
How do i turn the green light off from the webcam i cant switch it off
the switch is to control the light if this is turn on or turn off
There are such devices that, when clapping, can turn on or off.
your brake switch is either broken or out of alignment look above the brake pedal in your vehicle and make sure the switch is not hanging. The switch has to be closed to turn the lights off.
replace the head light switch. the coils in the switch get hot n turn off the lights.
there are a couple of settings you need to turn the light off at the light switch. it will then only come on if a door is open any time you want to use it ,you can switch it on or off at the light switch you can turn it off at the light switch on the dash it will then come on when you open a door any other time you want to use the cargo light you can switch it on or off at the light switch
On the turn signal indicator arm. Switch on the headlights, make sure the high beam is off, then pull out the rotating light switch.
If you are referring to the can light, there is a manual switch on the light that allows it to operate when the doors is closed or to automatically turn on when the door is open and then shut off when the door is closed. If the switch is in this position and the light is staying on, the switch in the door to tell it to turn off is probably not working.

Perhaps by unscrewing the bulb light.
