Answer for USA, Canada and countries running a 60 Hz supply service.
A point to remember is every switch has a hot wire connected to it even if the switch is turned off. Electricians almost never use a switch to isolate the power when working in a circuit. Go back to the electrical distribution panel and turn off the breaker, This will cut the voltage to the switch completely. In a second senerio you could have run into a three wire circuit where there is a common neutral and two hot wires to produce two 120 volt circuits. If you open the neutrals that are wire nutted in the back of the switch junction box one of them will have voltage on it from the other circuit. Touch it and any ground and you will get a shock. This is the main reason that all splices in junction boxes should have pig tails on them. Pig tailing splices allows a device to be changed out without opening the cluster of neutrals and hot wires. Remember to practice safety and shut off the breaker before starting the job.
There is probably faulty circuitry behind the switch, and the electricity escapes into the switch, shocking you.
No, but they represent a shock hazard.
because its much safer to switch the hot wire then the neutral wire because if you are working on a light fixture for example and the switch is off if you ground yourself out to the neutral you become the load or return. a neutral shock can me more dangerous at times
go to the Help option in Matlab. It will not help at all.
A photocontrol uses light to activate the switch. When the sensor does not detect light the circuit is broken and the switch is deactivated.
It depend on where the switch is located in the circuit.
yes because it can shock or explode
It may be static electricity, or more possibly... an ungrounded light switch.
No, but they represent a shock hazard.
You can't feel a shock because there is a insulator which insulates the flow of electricity. That's why you can't feel a shock when you turn off a switch.
You cannot die from the normal shock that you get when you rub the floor and then touch a light switch, etc. The amount of electrical current that is sent through your body is harmless and will do no permanent damage to you or your organs. The shock you have to worry about is the one you would receive from getting struck by lightning.
It is the brakes light switch
where is brake light switch
To control a light with a switch, the switch has to be connected in series with the light fixture.
When installing a remote light switch one must first turn the power off. This will prevent shock or electrocution. Next, unscrew the plate currently on the wall and remove the switch and wire the new one with remote. Next remove the light from the ceiling and install the remote sensor. Place light cover back over light and turn power back on. Program and test remote control to ensure wiring was correctly installed.
Light switch was created in 1884.
i think that the light switch is shorting out are the auto light switch shorting for the thumb switch
turn head light switch till it clicks and theses your dome light switch...
