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

Who invented the three way light switch?

William J. Newton is credited with inventing the three-way light switch in 1916. The design allows for a light fixture to be controlled from two different locations.


What can a three-way switch be compared to?

A three-way switch can be compared to a traffic intersection where multiple roads meet. Just as a three-way switch allows control of a light fixture from three separate locations, a traffic intersection allows vehicles to be directed from multiple directions. Both systems involve managing the flow of traffic or electricity from various entry points.


How do you connect a 3 wire fixture to a 2 wire fixture that are connected to the same switch what do you connect the red wire to?

A three wire fixture most likely is one that has two separate loads within it. An example is a ceiling fan with a light fixture. If the three wire is used to separately switch the two loads you have to make a decision as to which load you want to work with the two wire fixture. Once that decision has been made connect the two wire fixture in parallel with the your selected load on the three wire fixture. On these types of installations the three wire fixture is usually controlled by two separate switches in a two gang box. The red and black wires of the three wire terminates on the bottom of either switch. The white wire is connected to the incoming neutral. The top of the switches are paralleled together with the "hot" feeder from the distribution source.


Intermediate switch layout?

An intermediate switch layout involves two switches controlling a single light fixture. One switch is typically located at each end of a corridor or staircase, allowing the light to be turned on or off from either location. This layout requires a three-core and earth cable to connect the switches and the light fixture.


What is another name for a three-way switch?

Another name for a three-way switch is a "double pole switch." This type of switch allows for controlling a single light or fixture from two different locations, making it useful for hallways or large rooms with multiple entrances. The term "three-way" refers to the fact that it has three terminals for connecting wires.

How does a 3 wire dimmer switch function in a lighting system?

A 3-wire dimmer switch works by controlling the flow of electricity to the light fixture. It has three wires - one for power, one for the light fixture, and one for ground. When the switch is adjusted, it regulates the amount of electricity sent to the light, allowing you to adjust the brightness.


How does a 3 way dimmer light switch work to control the brightness of a light fixture in a room?

A 3-way dimmer light switch works by adjusting the amount of electricity flowing to the light fixture. This allows you to control the brightness of the light by increasing or decreasing the voltage. The switch has three terminals that connect to the power source, the light fixture, and another switch. By toggling the switch up or down, you can adjust the brightness of the light in the room.


What is the 3 switch wiring diagram for controlling a single light fixture?

A 3 switch wiring diagram for controlling a single light fixture involves three switches that can turn the light on or off from different locations. The wiring setup includes connecting the switches in a specific way to control the flow of electricity to the light fixture.


How does a three-way switch function in a lighting circuit to control a single light fixture from two different locations?

A three-way switch in a lighting circuit allows you to control a single light fixture from two different locations. The switch has three terminals that are connected to the power source and the light fixture. By flipping the switch up or down at either location, you can turn the light on or off. The switches work together to alternate the flow of electricity, allowing you to control the light from multiple spots.


Can you provide a three-way switch diagram for wiring a light fixture?

A three-way switch diagram for wiring a light fixture shows two switches controlling one light. The diagram includes the light fixture, two three-way switches, and the wiring connections between them.


How does a three wire light switch function in a typical electrical circuit?

A three-wire light switch functions by controlling the flow of electricity in a circuit using three wires: a hot wire, a switched wire, and a neutral wire. When the switch is turned on, it connects the hot wire to the switched wire, allowing electricity to flow to the light fixture. When the switch is turned off, the connection is broken, cutting off the electricity flow and turning off the light.


Can you provide me with three way switch diagrams for better understanding of the wiring configuration?

A three-way switch setup involves two switches controlling one light fixture. Here are three common diagrams to help you understand the wiring configuration: Standard Three-Way Switch Diagram: This diagram shows two switches connected to a light fixture with a traveler wire running between them. Three-Way Switch with Power Source at Light Fixture: In this setup, the power source connects to the light fixture, and two switches control the light. Three-Way Switch with Power Source at One Switch: Here, the power source connects to one of the switches, and the other switch controls the light fixture. These diagrams can help you visualize how the switches, wires, and light fixture are connected in a three-way switch configuration.


How does a 3-way light switch work to control the lighting in a room?

A 3-way light switch works by allowing you to control a light fixture from two different locations. The switch has three terminals, with one terminal connected to the power source and the other two connected to the light fixture. By flipping the switch up or down, you can change the flow of electricity and turn the light on or off from either location.


How does a three-way switch work in a lighting circuit?

A three-way switch in a lighting circuit allows you to control a single light fixture from two different locations. It uses two switches to alternate the flow of electricity, allowing you to turn the light on or off from either switch.


How can I install a 3-way switch for a light fixture with the light in the middle?

To install a 3-way switch for a light fixture with the light in the middle, you will need to connect the switches and the light fixture using three-way wiring. This involves running a three-wire cable between the switches and the light fixture, and properly connecting the wires to the switches and the light fixture. It's important to follow the wiring diagram for 3-way switches to ensure the switches work correctly to control the light fixture from two different locations.


How do three way switches work in a lighting circuit?

Three-way switches work in a lighting circuit by allowing you to control a single light fixture from two different locations. When one switch is flipped, it changes the flow of electricity to the light, turning it on or off. The second switch then works in conjunction with the first switch to control the light.


How does a three-way switch work to control the lighting in a room?

A three-way switch is a type of electrical switch that allows you to control a light fixture from two different locations. It works by using two switches that are connected to the same light fixture. When one switch is turned on, it sends power to the light fixture, and when the other switch is turned on, it breaks the circuit and turns off the light. This allows you to turn the light on or off from either switch, providing convenience and flexibility in controlling the lighting in a room.
