4-way toggle switch diagram

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.

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 a 4-way switch is wired?

Typical 4-Way Switch Wiring, NM Cable Switch 1 pair of traveler terminals connects to the top or bottom pair of traveler terminals on switch 2 . The other pair of switch 2 travelers connect the traveler terminals of switch 3. The switch 3 common terminal connects to the load (lights).

How many 4-way switches can you put in a circuit?

There is no limit to the number of 4-way switches that can be used to control lighting as long as the electrical wiring has been installed appropriately, and it isn't that difficult.

How many switches are in a 4 way switch?

Conventional 4-Way Switch Wiring Using 3 Switches 4-way switches have four terminals each with two pairs of travelers (one pair usually black and and the other pair brass color). A three switch configuration will have two 3-way switches, one on each end and one 4-way switche in the middle.

How many 4 way switches are required to control a light from five locations?

Just connect three 4-way switches in the middle of the two, 3-way switches as shown in the wiring diagam. The circuit is capable of controlling the light bulb from five different locations.

What is in and out on a 4 way switch?

The 4-way terminals are labeled “In” and “Out” (two of each). The mechanics of this switch are simple, in that they either switch the travellers straight through, or criss-cross them. To add more than three locations for one set of lights, you would just insert more 4-way switches in between the two 3-ways.

Does in and out matter on 4 way switch?

They are easier to understand than three-way switches. They have two terminals at each end of the switch body and connect to the travelers in-line between the three-way switches, in-coming at one end of the switch body, out-going at the other end. It doesn't matter which way the four-way switches face.

Is black wire input or 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".

How do you install a 4-way switch?

In this application where two 3way switches already exist, a 4way switch may be added by simply installing two 2-wire with ground cables of the same wire gauge as the circuit wiring from either of the 3way light switches to the location of the new 4way switch.

Why is there 4 wires in my light switch?

The black is the "hot" wire, the white is the neutral, and the copper is the ground. When you put a switch in a circuit you now have 6 wires - three coming in and three going out. Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving.

How many wires enter the switch box at the 4-way switch location?

There are four wires that are terminated (fastened to) a 4-way switch, plus the green or bare ground wire. In nearly every case, these wires will enter the wall box in two separate cables.

When should you use a 4 way switch?

Four-way switches are used to control lighting from three or more locations. Four-way switches are used in combination with 3-way switches. There are four terminals that provide two sets of toggle positions on a 4-way switch.

Is a double pole switch the same as a 4 way switch?

Double pole light switches, also known as a four-way switch, are two single pole switches put together. Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit.

Do I need a 3-way or 4 way switch?

38 Three and four-way switching As a rule, we must always install 3-way switches in pairs, and then as many 4-way switches as necessary. For example, if a light is to be controlled from four different locations we would need two 3-way switches and two 4-way switches.

How do you troubleshoot 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.

Can you put a dimmer on a 4-way switch?

Anyway, in a 4-way circuit (or more-way), you can replace either 3-way on/off switch (which will either be the first or last switch) with a 3-way dimmer. But it must be a 3-way dimmer, not a basic dimmer.

Can you replace a 4-way switch with a 3-way switch?

The two traveling wires can be swapped either way with no bad effect. If you want to abandon the other 3-way, you cannot remove or cover the box. You must remove the switch, rewire the circuitry, and install an approved cover plate.

Which switch must be closed in order to power the light bulb?

Switches in Parallel Switch S1 OR Switch S2 (or both of them) must be closed to light the lamp.

What kind of switch controls lights from two locations?

Three-way switches are commonly used to control one light fixture from two different locations. For example, a long hallway or stairway might use a three-way switch at each end so that lights can be turned on when approaching one end of the hall or stairway, then shut off from the other end.
