How to connect 4-way light 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.

How do you hook up 4 lights to one switch?

You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a "home run" configuration.

How does a 4 way light 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.

What does in and out mean 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.

Is there a common terminal on a 4 way switch?

A 3-way switch has three terminals and can control a fixture from two locations. Like these, a 4-way device has a ground terminal, but can control one fixture from at least three different locations. There are four terminals connecting to wires serving your lighting.

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.

How do you wire a 4 wire switch to a 3 wire?

Connect the ground wire of the 3-wire cable to the ground wire of the 4-wire cable. Connect the black wire of the 3-wire circuit to either the red or the black wire of the 4-wire circuit. The red and black wires are the"hot" wires. Either wire can be used to power a circuit.

Can I use a 3 way switch for a 4 way?

Sure, a 4-way is essentially two 3-ways in one device. Usually a 4 way switch has 2 (IN) screws and 2 (OUT) screws. Using one of the (IN) terminals is the same as the common terminal on a 3 way.

How can you tell if a switch is 4-way?

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.

Why are there 4 wires on my light switch?

A regular switch with two wires is called a “switch”. If two switches can control the same light, they are called “three-way switches” (go figure) and they need three wires. If you want to have more than two switches control the light, you use switches that have four wires (“four-way switches”, IIRC).

How do you test a 4-way light switch?

Four-way switch: Clip the wire of the continuity tester to one of the darker screw terminals, then touch the other wire to the lighter, brass-colored terminal on the same side of the switch. Flip the toggle lever back and forth: The test should show continuity when the lever is in one position, but not both.

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 many Poles is 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 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 are the pair terminals of a four way switch?

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.

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.

What is the difference between a 3 way and 4 way switch?

For example, with a 3-way switch (such as the TM873W ) one light load could be controlled from up to two different locations. Whereas a 4-way switch (such as the TM874W) allows for control of one light load from up to three different locations.

Why would you use a double pole switch?

The double pole diverter switch is used to divert two current lines to another pair of lines; its applications are in household appliances as well as in domestic and industrial electrical installations.

What are the 4 types of light switches?

Most of the common types of switches come in different styles, such as toggle, rocker, slider, or push-button. The style usually does not affect the switch function and electrical wiring, though it can make the selection process confusing.
