Presuming the switch worked at one point and just stopped working it is likely that the switch has failed in a normally closed position. The only other possibility is that somehow you have a wire problem whereby the hot side of supply is connected to the load side of the switch. This could be caused by an exposed wire in the switch receptacle. Suggest you turn off power at breaker and replace switch as a start. When you have the switch removed from the receptacle, with wires still connected see if switch works. If it does it could still be bad, but examine the wires around switch and see if you have any exposed wire that could be touching the load side of the switch (Side connected to the light).
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.
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.
To control a light with a switch, the switch has to be connected in series with the light fixture.
Check stop light switch for misadjustment or defect
To operate a light switch, you simply flip the switch up to turn the light on and flip it down to turn the light off.
Check the brake light switch.
well most people say turn off the light but you could say switch of the light.
your on off switch may be bad, get it checked.
To operate a light switch, simply flip the switch up to turn the light on, and flip it down to turn the light off.
The brake light switch might not be connected properly. Remove the brake light switch for 10 seconds and replace it to its original position.
Check the brake light switch down on the brake pedal.
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.
A bad relay switch will cause the windshield wipers to not turn off. Replace the relay switch and the windshield wipers should turn off.
To use your light switch, simply flip it up to turn the light on, and flip it down to turn the light off.
To operate a toggle light switch, simply flip the switch up to turn the light on and flip it down to turn the light off.
