How does a 4-way electrical switch work?

A four-way switch is similar to a three-way, except it has four terminals (plus a ground terminal) and controls one fixture from three locations. This type of switch must be combined between two three-way switches to form a circuit. While more uncommon, this is a good option for large rooms with several entrances.

Does a 4-way switch have input and output?

4-way switches can be quickly identified by the 4 screw terminals (in addition to the green/gnd screw terminal). Two of the terminals are brass and labeled "input", the other two are black and labeled "output". It is very important to pay attention to these as shown in the 4-way switch diagram.

What are the terminals on a 4-way switch?

4-way switches have four terminals on them: two for traveller wires coming in, and two for traveller wires going out. The device will usually indicate which two terminals are for “incoming” and “outgoing” wires.

How do you test a 4-way switch?

Test a 4-Way Switch Turn off power to the switches at the circuit breaker and using a tester, make sure power is off. Remove all of the switches so you can access the switch terminals. The wire connections do not have to be removed. Using a continuity tester, check continuity between terminals as shown.

Why does light switch have 4 wires?

Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving. The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires.

4-way switches are generally used for controlling the light from three or more switches or locations (co uld be each floor of the stairs, for example). These switches are employed in circuits along with the linked 3-way switches.

Where should the wires be on a 3 way switch?

The wires from the first 3-way switch should be connected to the brass terminal (doesn’t make a difference which one to which side) and the second 3-way switch should be connected to the dark set of terminal screws.

What format are schematics and wiring diagrams in?

Here are the above diagrams in PDF format ( schematics & wiring ).

How many screws does a 3 way switch have?

If you compare this switch to other variations, the 3-way switch will have four screws (or terminals) and the 2-way (casual/normally used “single-pole” switch) will have only three screws (or terminals).

What is the best way to test if a switch is connected to a terminal?

In order to figure out which terminals are linked, you can use an ohmmeter (or multimeter) for testing.

What is 14-2 wire?

In the picture given above, a 14-2 cable (2 wires with the ground) is being used and it is running from the light fixtures to the three-way switch. A Three-wire cable with the ground (or 14-3 cable) is employed to take power to the 4 way switch and another 14-3 cable is used for connecting the last 3-way switch where the circuit ends.

What color wire goes to the brass screws?

Once you take out the wires from the cable and start connecting them, you may end up with red (traveler) wire going to the brass-colored screws (or terminals) and black (hot) wire to the black (or dark) colored screws (or terminals).

How many wires are needed for a 4 way switch?

A 4 way switch must be wired between two 3 way switches as shown in the diagrams on this page. A 4 way switch has five terminals: one ground and 4 circuit terminals divided into two matching pairs called travelers. Each pair of traveler terminals should be wired to the traveler wires from one of the 3 way switches in the circuit. The travelers from one 3 way can be wired to either terminal in a pair, but don't mix up the pairs on the 4 way or the circuit won't work properly.

What are the black and red wires on a 4 way switch?

The black and red wires running between the switches are used to connect the travelers on each switch. Take note that the traveler wires from SW1 are connected to the T1 pair on the 4 way switch and the travelers going to SW2 are connected to the T2 pair.

What are the wires on a light switch?

The red and white wires from SW 1 are used as the travelers, at the light box they are spliced to the red and white running to the 4 way switch. The white wire is marked black on both ends to label it as hot. The black wire running to the 4 way is connected to the hot on the fixture and at the switch box it's spliced to the black wire running to the common on SW2. The red and white wires running to SW2 are used as travelers and again, the white is marked black on the ends.

How to check if a 4 way switch is a neutral?

Also, confirm that each pair of travelers on a 4 way are only connected to one switch per pair. Check that the neutral from the source is only connected to the neutral terminal at the load. A neutral wire will never be connected to standard 3 way and 4 way switches, although some smart switches and timers may make use of a neutral wire to operate the device. If you believe your circuit is wired correctly and the lights still don't work, one or more of the switches may be defective. You can test the switches using the procedure described below.

What is the common terminal on a 3 way switch?

The common terminal on the 3 way switch at the end of the circuit connects to the black wire running to the hot terminal on the light. Take note that the traveler wires from SW1 are connected to the T1 pair on the 4 way switch and the travelers going to SW2 are connected to the T2 pair. Each pair of traveler terminals on ...

How to test a 3 way switch?

To test a 3 way switch, connect one meter probe to the common terminal and the other to one of the travelers. Flip the switch toggle one way and then the other. If the meter shows continuity with the toggle in one direction and not the other, move the probe from that traveler terminal to the other one and test again. If you find the second traveler shows continuity with the toggle in one direction and not the other, the switch is probably functioning properly. If, however, you don't find any continuity or constant continuity no matter where the probe is or how you flip the toggle, the switch is likely defective and should be replaced.

What is a 3 wire dimmer?

Three-wire cable runs between all the switches and 2-wire cable runs to the light. To make this circuit work, a 3 way dimmer can be used in place of one, or both of the standard 3 way switches. In fact, a dimmer can be used this way in place of any of the 3 way switches on this page.

What is a three way switch?

A three-way switch connects traveler wires from that switch to one side of the four-way switch, while the other side is connected to the other three-way switch, and the three-way switch is then connected to a light. When connected properly, a simple flip of any of the switches will turn on the light.

How many terminals are there in a four way switch?

There are four terminals that provide two sets of toggle positions on a four-way switch. Each set of terminals is one of the toggle positions. When the switch is in the up position, the current can flow through two terminals. In the down position, the current flows through the other two terminals. Many times, four-way switches will come ...

How to tell which terminals go together?

To find out which terminals go together, you can use an ohm meter to test the terminals and the toggle positions, or take a quick look at the manufacturer's instructions, which should outline the pairings. Each set of terminals will connect to the traveler wires from each of the three-way switches. When connected properly, you'll be able to turn lights on from either of the three-way switches or the four-way switch. In the event that you need to switch lighting from more than three locations, simply add additional four-way switches between the two three-way switches.

How many switches do you need for a living room?
