Good question, I have 3 in a circut, 2 at 120V, and one at 14V. Already replaced the outlet thinking that was bad, same result. More than likely there are defective connections somewhere in the wiring. Possibly under a wire nut. It could be all or none of the above. All depends where you put your volt meter to do the reading. With the light switch in the off position when you measure across the switch you will get line voltage of 120 volt, but when you turn on the light, it will read the voltage drop of the switch, should be 0 volts unless the connection is bad or if it is a dimmer switch then the voltage will be all over the place. from: bmetong
A switch in a circuit will quickly allow you to break the circuit, without changing the wiring. For example, a light switch. By turning a light switch off, you are breaking the circuit and, thus, turning the light off.
That is called a 4 way light switch circuit. On each end of the circuit you install a 3way switch and in the middle you install a 4 way switch.Answer using British TerminologyIn the UK, 'three-way' switches are called 'two-way' switches (more logical, if you think about it!), and the 'four-way' switch is called an 'intermediate' switch.
Send power to the 1st switch and then send the power from that switch when it is in the on position to the second switch. Then send power to the light from the second switch. That way both switches will have to be in the on position for the light to be on.
That is called 4 way intermediate switch wiring. Click the link to watch a video I have posted showing how to wire just such a circuit.
There is a relay switch in the circuit which switches the light on & off when you activate the turn signal.
All circuits including those with switches will have a breaker protecting the circuit. To find, turn on the light controlled by the switch and then turn off breakers one-by-one until light goes out.
A single-pole switch is an on/off switch that switches a single wire such as the circuit to your overhead light. A double pole switch is also an on/off switch that switches two wires. You would use this to switch as 240 volt circuit (which requires two hot wires) or if you had two circuit you wanted to switch at the same time. I've used them when I had two large light circuits that required two breakers that I wanted to switch with one switch.
An AND circuit is a circuit that takes two or more inputs, and generates an output that is the boolean AND function of those inputs. Two light switches in series, for instance, is an AND circuit because both switches have to be on for the light to be on. If the switches were wired in parallel to each other, and then in series with the light, that would be an OR circuit.
The "sw" is electrical terminology for the word "switch". A single pole switch is one that opens the circuit when in the off position and closes the circuit when in the on position. Individual switches that turn on light fixtures in your home are in the classification of single pole switches.
If your wiring it up for a light switch, then you will need 2 3 way switches, this will allow you to turn on and off lights from 2 locations
In a light switch factory......
Answering the LITERAL question, generally slide switches are soldered into a circuit. But to answer the question of what a 3 conductor slide switch can do for a circuit: A slide switch can allow the circuit designer to select between two choices, perhaps causing a switch to illuminate either the white light or the blue light. Since some slide switches only allow the two options, that would be all THAT slide switch could do. But other slide switches have other abilities, for them a center position allows the circuit designer to select between the two lights OR, but putting the switch in the center position, both lights would be off. Other slide switches include an internal resistor that allows for a fading effect, allowing for a light to be ON, OFF or some varying state between.
When a light switch is opened the circuit is broken and the light goes out.
When the light switch is turned on and a light bulb is connected in the circuit a current will flow through the circuit. Likewise when the switch is opened, the current will stop flowing in the circuit.
3-Way switch. Google "3-way switch" for wiring diagram.
First answer: No. Second answer: Yes. A light bulb is a resistance. Current flows across a tungsten filament, heating it to produce light. However, if there was some other resistance wired into a closed circuit, a screw type bulb could be used as a switch. You unscrew it to throw open the circuit, effectively turning off whatever else was wired in the line. Screw it back in to switch it on. So yes, you could use a light bulb as a switch. Some switches have LED (light emitting diodes) built into them so they light up when the switch is closed, and turn off when the switch is open. And some switches are wired just the opposite, so the LED is on when the switch is off. This makes these types of switches easier to find in the dark.
A 3 way wall switch is used in a circuit for two switches that can turn a light fixture on or off from two different locations. Both switches must be 3 way switches. For more information see the answers to the Related Questions shown below.
The switch completes the circuit, it is no longer interrupted, thus creating electrical current through the switch area. A power grid is just a giant circuit with many resistors and switches. The switch is an interrupting device in which the power of a grid flow by a certain area instead of through it.
Its means there is no continuity between point Ato point B. Ex. A light switch : When the switch is off it opens the circuit and electricity does not get to the light, when the switch is on the circuit is closed and the light will turn on.
When you turn on a light switch you do not have an open circuit.
A pull-string or pull-chain switch IS a light switch. Some other types of light switches are called wall switches and cord switches.For more information see the answers to the Related questions shown below.
This is called a 3-way circuit. It uses special switches and wiring to control a load from more than one location.
It is dependant on whether the switches are in wired in a parallel or series configuration. If the switches are wires in parallel then both switches would have to be off to turn the light bulb off. Either switch could turn the light bulb on. If the switches are wired in series then both switches would have to be on to turn the light bulb on. Either switch could turn the light bulb off.
A switch simply opens a circuit, stopping the flow of electricity. For example: a simple circuit would be two wires from a battery, one of which goes to a switch, and the other goes to a light bulb. A third wire goes from the other side of the switch to the other conductor of the light bulb. With the switch closed the circuit is complete and the light goes on. Open the switch and the circuit is broken and the light goes off.
One 1,000 watt light will push a typical circuit breaker close to its limit. Six such lights will require wiring and circuit breakers to handle the load. Figure one circuit breaker per light. That means not only six switches but six switches, each on a different circuit breaker. Don't overload the wiring or it could cause a fire.
